A magnetic shield 66 or anti-magnetic housing is provided for protecting the electronics from magnetic fields. More specifically, the magnetic drive arrangement 60 includes the magnetic coupling 64 attached to and contained within the drive shaft 62. Rotation of the drive shaft 62 provides the mechanical energy, i.e., force and torque, to drive the gear train drive 30, in that the drive shaft 62 is mechanically coupled to the gear drive train 30.

An electronics package 68 is provided within the register 20. The electronic package 68 includes the board 70 that has a microprocessor 72 which is electrically coupled to the batteries 50 and 52.

The register 20 includes an antenna 74 is electronically coupled to the microprocessor 72. As shown in FIG. 6, the antenna 74 includes an arc-shaped section 76 having a leg 78 depending therefrom and a bottom substantially circular section 80. Coaxial cable 82 is electrically coupled to the arc-shaped section 76 and the circular section 80 and electrically coupled to the microprocessor 72 as shown in phantom. This type of antenna is known as a PIFA antenna. The arc-shaped section 76 is the radiating plane and the circular section 80 is the ground plane. The leg 78 causes a short circuit between the radiating plane and the ground plane. The inner conductor of the coaxial cable 82 is electrically connected to the radiating plane and the outer conductor of the coaxial cable is connected to the ground plane.

More specifically, the antenna 74 includes a first electrically conductive sheet 80, a second electrically coupled conductive sheet 76 spaced a first distance apart X from the first metallic sheet 80, and an axially extending leg 78 electrically connected to the first electrically conductive sheet 80 and the second electrically conductive sheet 76. The axially extending leg 78 is likewise electrically conductive. Preferably, the first electrically conductive sheet 80, the second electrically conductive sheet 76, and the axially extending leg 78 are made of metal. More preferably, the first electrically conductive sheet 80, the second electrically conductive sheet 76 and the axially extending member 78 are made from a unitary sheet of metal. The first electrically conductive sheet 80 has a first arcuate-shaped outer edge 100 and the second electrically conductive sheet 76 has a second arcuate outer edge 102 wherein the axially extending member 78 extends from the first arcuate-shaped outer edge 100 to the second arcuate-shaped outer edge 102. The first arcuate-shaped outer edge 100 has a first radius R₁ extending from a first center point 104 and a second arcuate-shaped outer edge 102 has a second radius R₂ extending from a second center point 106. The first center point 104 and the second center point 106 are contained on a center line 108. The first electrically conductive sheet 80 and the second electrically conductive sheet 76 are contained in a first plane 109 and a second plane 110, respectively. The first electrically conductive sheet 80 has a first surface area 112 and a second electrically conductive sheet 76 has a second surface area 114, wherein the first surface area 112 is greater than the second surface area 114. Both the first electrically conductive sheet 80 and the second electrically conductive sheet 76 include cut-out sections 116. The cut-out sections 116 permit the antenna 74 to be accommodated by the meter register 20 by permitting other register components to be received by the cut-out sections 116. For example, the reed switches 54 and 56 are contained within one of the cut-out sections 116. As stated previously, the coaxial cable 82 is electrically coupled to the first electrically conductive sheet 80 and the second electrically conductive sheet 76. Preferably, the distance X is approximately equal to or a multiple of a wavelength distance to be transmitted from the antenna 74. Essentially, the axially extending leg 78 has a length equal to X. Although the antenna 74 shows substantially arcuate and circular sheets, the sheets can also be other shapes, such as rectangular or square, for example.

The metallic cup 24 is electrically coupled to the first electrically conductive sheet 80 and the second electrically conductive sheet 76. The cup 24 is an opened top structure having a cylindrically-shaped side wall 118 attached to a bottom wall 120. The bottom wall 120 slopes away from the opened top portion toward a central axis 122 passing through the cup 24. Preferably, a portion 124 of the bottom wall 120 is frusta-conical in shape. The bottom wall 120 includes a flat central portion 126 connected to an end 128 of the frusta-conical portion 124 that is adapted to receive the magnetic coupling 64. Preferably, the first electrically conductive sheet 80 includes tabs 130 extending therefrom used for contacting the metallic cup 24.

The first electrically conductive sheet 80 is spaced a second distance Y from the bottom wall 120, which is approximately equal to or a multiple of a wavelength to be transmitted by the antenna 74. A portion of the subassembly 26, which includes a mechanical portion 132 of the register 20, that includes the gear train drive 30 is received between the first conductive sheet 80 and the second conductive sheet 76. The electronic package 68 includes an electrical frequency generator 134 coupled to the first conductive sheet 80 via the coaxial cable 82.

The antenna 74 is coupled to the power source, i.e., the batteries 50 and 52, via the frequency generator 134. More specifically, the board 70 includes the frequency generator 134 which is electrically coupled to the first electrically coupled sheet 80.

This present arrangement results in a very compact sealed register 20 which has an internal antenna. The metallic cup 24 also acts as an amplifier for the antenna 74 and forms an antenna structure. The metallic cup 24 also amplifies the radio waves that are emitted from the antenna 74 so that they may be directed externally of the register 20 as shown in FIGS. 2, 3, and 11. Furthermore, it has been found that electrically coupling the register 20 to a metallic meter case, such as the body 12, further amplifies the signal.

Referring back to the meter register 20, the mechanical portion of the meter register includes a register body 136 having the rotatable shaft or drive shaft 62 coupled thereto. A drive gear 138 is attached to the drive shaft 62 and at least one follower gear 32 is rotatably attached to the register body 136 coupled to the drive gear 138. The antenna 74 is attached to the register body 136, which is sandwiched between the first electrically conductive sheet 80 and the second electrically conductive sheet 76. The odometer 40 is coupled to the drive gear 138 and at least one follower gear 32. The rotatable drive shaft 62 includes a magnetic member or coupling 64 attached to a first end and the indicator 29 which attaches to a second end. The register drive shaft 62 extends along the longitudinal axis 122 and the first electrically conductive sheet 80 is contained in the first plane 109 and the second electrically conductive sheet 76 is contained in a second plane 110, the longitudinal axis 122 being normal to the first plane 109 and the second plane 110.

Referring to FIG. 9, a sensing follower gear 32s is rotatably secured to the body 136 and coacts with the drive gear 138 via a gear train drive 30 or through direct coupling. The sensing follower gear 32s rotates about a sensing axis 140 and drives the magnet arrangement 34. The magnet arrangement 34 includes at least one sensing magnet 142 that coacts with the sensing follower gear 32s and is radially spaced from the sensing axis 140. When the sensing follower gear 32s rotates about the sensing axis 140, the sensing magnet 142 rotates about the sensing axis 140 in a rotating magnetic plane 144. The reed switches 54 and 56 are radially spaced. When the sensing magnet 142 and the reed switches 54 and 56 are radially aligned, the reed switches 54 and 56 are in a first state, and when the sensing magnet 142 is not radially aligned with the reed switches 54 and 56, the reed switches 54 and 56 are in a second state. Also, only one of the reed switches 54 and 56 will be in a first or second state depending on the position of the sensing magnet 142 relative to the reed switches 54 and 56.

A rotational direction of the sensing follower gear 32s can therefore be determined by monitoring the sequence of the first state and second state of the reed switches 54 and 56 as shown in FIG. 10. The reed switches 54 and 56 are electrically coupled to the microprocessor 72 which can determine the rotational direction of the magnet arrangement 34, which in turn can determine the rotational direction of the measuring chamber 14. In this manner, one can determine if a reverse flow or forward flow condition is occurring through the meter 10 as shown in FIG. 10, since one can determine the direction of rotation of the driveshaft 62. More particularly, as can be seen in FIGS. 8-10, the magnet 142 rotates about the sensing axis 140. Each reed switch 54 and 56 is activated depending on the proximity of the magnet 142 to the reed switches 54 and 56. The magnet 142 rotates about a circular path PA. The path PA can be divided into four segments: αβ, βγ, γδ, and δα when the magnet 142 is in the segment αβ, the reed switch 54 is in the first state or activated state designated as one (1) in FIG. 10, and the reed switch 56 is in a second state or deactivated state and designated as zero (0) in FIG. 10. When the magnet 142 is in the segment by βγ, the reed switches 54 and 56 are in the first state or activated state and designated as one's (1) in FIG. 10. When the magnet 142 is in the segment γδ, the reed switch 54 is in the second state or deactivated state designated as zero (0) in FIG. 10 and the reed switch 56 is in the first state or activated state designated as one (1) in FIG. 10. Finally, if the magnet 142 is in the segment δα, both reed switches 54 and 56 are in the deactivated state or second state designated as zero's (0) in FIG. 10. Depending on the sequence of the magnet position and the state of the reed switches 54 and 56, the direction of rotation can be determined.

Also, a magnetically activated switch or reed switch 148 can be provided with the register 20 and coupled to the microprocessor 72. The reed switch 148 is electrically coupled to the microprocessor 72 wherein when a magnetic field activates the magnetically activated switch 148 for a fixed period of time, the register 20 and/or antenna 74 emits a signal that indicates the register has been tampered with.

Preferably, the face cap 22 and metallic cup 24 form the internal seal chamber C via an elastomeric sealing member wherein the sealed chamber receives the register body 12. Preferably, the internal chamber C is at a pressure below atmospheric pressure and, more preferably, at a pressure minus 9 atmospheres. Hence, the microprocessor 72 and antenna 74 are maintained in the evacuated internal chamber C.

In various cases, the meter, particularly the water meter 10, is contained in a pit 150, as shown in FIG. 14, positioned in the ground. In this arrangement, the radio wave signals of the antenna 74 cannot radiate a great distance due to the properties of the pit 150. Further, in some instances, the pit 150 may fill with water 152 further hampering the transmission capability of the antenna 74. In such instances, an auxiliary antenna 154 is provided. As shown in FIG. 15, the auxiliary antenna 154 includes a circular metallic ring 156 that is adapted to be glued or fixedly attached to the face cap 22. A first pit electrically conductive sheet 158 and a second pit electrically conductive sheet 160 are provided. An electric insulator is provided between the two sheets 158 and 160, hence, sheets 158 and 160 are spaced apart. An electrically conductive wire or cable 162 attaches the circular metallic ring 156 to the first pit electrically conductive sheet or radiating plane 158 and the second pit electrically conductive sheet or ground plane 160 via a short circuit element 163. The first pit electrically conductive sheet 158 and the second pit electrically conductive sheet 160 are adapted to be positioned above a pit lid 164. The first pit electrically conductive sheet 158, second pit electrically conductive sheet 160, and short circuit element 163 also form a PIFA antenna. Further, the first pit electrically conductive sheet 158, second pit electrically conductive sheet 160, the circular metallic ring 156, and the cable 162 are encased in a polymeric coating or waterproof coating 166 so that should the pit 150 fill with water 152, the auxiliary antenna 154 is not affected. Preferably, the first pit electrically conductive sheet 158 and second pit electrically conductive sheet 160 are circular in shape and are made from one unitary metallic sheet, such as copper, along with the short circuit element 163, like antenna 74. The axial spacing X′ of the first pit electrically conductive sheet 158 and the second pit electrically conductive sheet 160 is equal to or a multiple of the wavelength of the frequency transmitted by the antenna 74. It is important to note that no external power source, such as batteries, supply power to the auxiliary antenna 154. The radio waves transmitted from antenna 74 are received by the ring 156, pass through the cable 162, and are then transmitted via conductive sheets 158 and 160.

The approximate direction of one antenna 74 is as follows: diameter of the circular section 80 is approximately 2.5″; distance X is approximately 0.75″; and diameter of the arc-shaped section 76′ is approximately 2.5″ for approximately 180°. Likewise, the circular sheets 158 and 160 have a diameter of approximately 2.5″ and spaced apart a distance X′ of approximately 0.75″. It is important to note that no separate electrical power is provided to the auxiliary antenna 154 and that an antenna signal 168 is generated external of the pit 150 via the first pit electrically conductive sheet 158 and the second pit electrically conductive sheet 160.

The following discusses operation of the present invention. Initially, water passes through the inlet 16 causing the measuring chamber 14 to rotate. The water then flows through the outlet 18. The measuring chamber 14 causes the magnetic drive 65 attached to the measuring chamber 14 to rotate. The corresponding magnetic coupling 64 provided in the register 20 is likewise rotated causing the drive shaft 62 to rotate. This in turn causes gears 32 of the gear train drive 30 to rotate which in turn causes the odometer 40 to move indicating the quantity of liquid flowing through the meter. At the same time, the magnet arrangement 34 rotates causing the sensing magnet 142 to rotate about the reed switches 54 and 56. Depending on the sequence of the states of the reed switches 54 and 56 as shown in FIG. 9 and previously discussed, the microprocessor 72 can determine the number of rotations of the measuring chamber and the direction of rotation. In this manner, a signal can be provided to the antenna 74 indicating the number of rotations which, in turn, determines the volumetric amount of fluid passing through the meter. Also, in this manner the position of the gear wheel 32s can be approximated by the state of the reed switches. The signal designated as 186 is then transmitted through the antenna 74 and, where applicable, the auxiliary antenna 154. In other words, depending on the situation, the antenna 74 may be used without the auxiliary antenna 154. The transmitted signal 186 is then picked up by a receiver 189. The receiver 189 may, for example, be attached to a vehicle 188 as shown in FIG. 12. The vehicle 188 receives various packets or information transmitted from the antenna 74. This information then can be transmitted to a central computer which then can provide the information to the end user through various means, including the internet. Alternatively, the meters 10 can be read by a meter reader individual going through each meter, i.e., an individual may carry a receiver and walk past the meters with the information transmitted by the respective antenna 74 and/or auxiliary antenna 154 to a receiver 189. Further, the information can be provided through a stationary receiver 190 which can then either transmit another radio wave signal or send the information through telephone lines or the equivalent. Also, the signals can be received to a concentrator which then can be provided to a central source, such as through an Application Service Provider (ASP), which will convert the information into a usable format, which both the utility and the user can access via the internet, for example. In this manner, neither the utility nor the user needs special software to obtain billing and usage information since the central source (ASP) would provide this information in a user-friendly format, as will be discussed below.

Once the water begins to flow from the inlet 16 to the outlet 18, the rotating element in the measuring chamber 14, such as a multi-jet wheel, rotates which in turn causes the magnetic coupling 64 to rotate. This causes the drive shaft 62 to rotate with the respective gear train drive 30. Hence, the dial 29 and the odometer 40 are caused to move. Likewise, the cruciform of the magnetic arrangement 34 rotates. In the present case, the magnetic arrangement 34 includes a single magnet 142. The magnetic field caused by the magnet magnetically coacts with the two reed switches 54 and 56. The state of the reed switches 54 and 56 are affected by the magnetic field of the magnet 142 to determine which sequence can be used to determine the direction of flow through the meter 10 such as, for example, the sequence of reed switches 54 and 56 is as follows: 0,0; 1,0; 1,1; 0,1; 0,0, etc., then this would indicate reverse flow. More than one magnet can be provided in the cruciform magnet arrangement. In the case of three magnets or an odd number of magnets provided in the cruciform section, directional flow can be determined. However, where only two oppositely positioned magnets are provided, or four magnets are provided, in each of the cruciform segments, only an indication of movement or the register can be determined, not the direction of rotation. More particularly, both flow rate and flow direction can be determined if the magnets are arranged in a non-symmetric arrangement about the cruciform, i.e., three magnets or two magnets positioned next to each other.

Further, the signal information provided via the antenna 74 may also include an odometer meter reading corresponding to the meter odometer 40. Furthermore, the register can transmit, periodically or nonperiodically, information through the antenna 74 and identify such information as the meter coating utility consumption. Further, the antenna 74 can not only transmit information signals but, likewise, can receive information signals 194 from a transmitter 196, that is a two-way communication. Preferably, this information can be used to correctly adjust the transmitted meter information indicating the odometer reading and other information. This permits the information to be transmitted via the meter register 20 to be modified in the field without removal of the meter register 20.

The microprocessor 72 can also provide other information related to the operation of the meter. For example, the register 20 can monitor the flow rate via the reed switches 54 and 56, through the meter and, if that information exceeds a fixed flow rate number or the flow rate does not change over a period of time, an alarm can be issued indicating that there may be a leak. In another example, the register 20 can monitor the flow rate via the reed switches 54 and 56 through the meter and determine if the measured flow rate is greater than zero. Specifically if, for example, the meter 10 can detect a flow rate Q as low as 1 liter or quart per hour and over a fixed period of time t, e.g., thirty minutes, and if Q/t over a fixed period of time, e.g., one hour, remains constant, then this could indicate a leak condition. A low constant flow rate over a period of time could indicate a small leak, such as in a toilet, or a large consistent flow rate over a period of time could indicate that a main water line has failed or a bathtub is overflowing. An alarm can be issued either at the location of the meter, or via e-mail or a telephone message, for example.

Preferably, the batteries 50 and 52 provide power to the electronics of the register at 10 milliwatts and power consumption is typical at 2 micro amperes. It is believed that in this arrangement the battery life can be approximately 8 years. Preferably, the antenna 74 transmits data having a 3.3-4 milliseconds length of compression data and the time between transmissions can vary, for example, 6 seconds or twice a day from the meter, depending on the particular situation. The meter 10 can also receive information, i.e., radio signals Q, from a transmitting source TS as shown in FIG. 11. More preferably, the present invention system transmits information through a series of character strings that essentially identify a base code, an I.D. code, a system code, an area code, a meter-type water consumption register, reverse flow consumption, status, and a billing factor. This information can be modified on a case-by-case basis. Preferably, the present invention transmits at radio frequencies of 10 dbm (10 mW) narrow band, 800-980 MHz frequency or any other radio frequency, for example, per FCC (United States Federal Communications Commission).

More preferably, the present invention can be utilized in connection with the vehicle 188 which can receive the meter reading signals 186 emitted from the register antenna 74. Specifically, the vehicle 188 can travel a set meter reading route. Along that route the vehicle receiving unit 189 will receive the various radio waves from respective meters 10. The vehicle 188 can be provided with computer assistance to store this information. This information, which includes consumption information, can be sent to a central computer for billing and other information. The vehicle receiving unit can identify if it does not receive the signal from the meter designated on the route. This may indicate that an antenna wire was cut and/or the register was tampered with. An alternative arrangement can be provided that the meter antenna transmits meter reading information to a communication concentrator. This information can be forwarded via a communication line, such as a modem line, or radio waves to a central computer for collation of the information. As described earlier, this information can then be sent to an ASP. This information can be analyzed for billing purposes.

Finally, the information transmitted via the antenna 74 can then be provided through a world-wide-web or internet-based system whereby the user or utility can obtain this information via typing into a computer the user's I.D. number and password at the ASP website. The present invention can also be used in the submetering market, where the submetering entity is responsible for collecting utility fees from users. Such information that may be obtained is meter usage 197a and billing information 197b via screens 198 and 200 such as shown in FIGS. 14 and 15. This information would be presented in real time. Therefore, if one wishes to monitor utility consumption, he or she need only to log onto this website from anywhere throughout the world where internet access is available. Further, utilities and users need not use special software packages to obtain the information since it would be provided by the web-based ASP that provides respective reports. Further, if it is believed that there is a leak occurring or tampering of the meter, an e-mail message 201 or automated message can be sent to the household or business for an emergency telephone number for further evaluation. For example, if a leak is detected in a home, the home owner could be e-mailed or telephoned at an emergency number to check whether a leak is occurring. Furthermore, a physical alarm can be provided on the meter, in which case, an alarm can be emitted from that meter. Also, an opening and closing valve can be provided on the pipe p, which can be remotely activated to an opened and/or closed position depending on the volume of water passing through the meter. As can be seen, the present invention solves many problems that are in existence in automatic meter reading technology. Further, the present invention can be used to measure any type of fluid, including water, gas, gasoline, etc., as well as any other type of metered materials.

Having described the presently preferred embodiments of this invention, it is to be understood that it may otherwise be embodied within the scope of the appended claims.
