RTR - Pit ORION Recordall Transmitter Register for Pit ORION Technical Brief DESCRIPTION APPLICATIONS: The Badger RTR Pit ORION RF system is designed for water meter pit or vault installations that are subject to flooding or submergence. The assembled system consists of the Recordall Transmitter Register (RTR) and the ORION Pit Module. The RTR is factory wired to the end cap assembly for maximum reliability; the Pit ORION is bottom mounted thru a drilled hole in the meter pit lid. The assembled RTR Pit ORION is designed to communicate with Badger interrogation devices, including handheld or mobile. OPERATION: The RTR provides a digital signal from Badger Meter's patented piezoelectric solid-state switch. This signal has the characteristics of an open drain Field Effect Transistor (FET) and has no electrical contacts to stick, wear or corrode. It is fully compatible with the input circuitry of the ORION Pit Module. The ORION Pit Module uses the RF bubble-up (broadcast) mode. RESOLUTION: Digital output from the RTR has resolution of 1/10th of the register test circle. Output resolution of the Pit ORION Module may vary with meter size. The resolution table on the back of this technical brief lists output resolution for all ORION meter applications. LEAK DETECTION: The Orion system provides optional leak detection notification when the meter is read. The system reports leak detection when a two hour window of no usage is found within a 24 hour time period. The system automatically resets when the next two hour window of no usage is found. MOUNTING: The RTR uses a bayonet connection compatible with all Recordall Disc, Turbo, Compound and Fire Series meters. A TORX seal screw is provided to allow positioning and to secure the RTR to the meter body in a tamper resistant mode. The RTR can be removed from the meter without disrupting service or disconnecting the Pit ORION. The RTR is factory wired to the Pit ORION Module. For best performance, the Pit ORION is mounted through the drilled hole in the lid, attached to the lid, and programmed by the utility in the field. If the Pit ORION system is mounted below the lid (not through the drilled hole) reduced performance will result. MAGNETIC DRIVE: Direct drive, high-strength, magnetic coupling through the meter body to the wetted magnet provides reliable and dependable register coupling. SEALED REGISTER: The RTR local register consists of a six-digit straight-reading mechanical odometer totalizer, a 360 test circle with sweep hand, and a flow finder to detect leaks. The register gearing is self-lubricating, thermoplastic to minimize friction and provide long, reliable life. Permanent sealing eliminates moisture, dirt, and other contaminants. TAMPER-PROOF FEATURES: Removal of the RTR from the meter can be minimized by using a tamper resistant TORX seal screw. TORX seal screws are provided as standard accessories with the RTR. Optional tamper detection seal wire screws are also available. CUT WIRE TAMPER INDICATION: The Pit ORION has the capability to detect a tamper should it exist. Proper setup in ORION Reading System software needed. CONSTRUCTION: The housing of the RTR is constructed of a tempered glass lens top and a copper alloy metal bottom. Internal construction materials are thermoplastic for long-life and high reliability. The integrity of the adhesive seal joining the glass top to the metal base provide unmatched protection in water meter applications. A corrosion and tamper resistant TORX seal screw is provided to secure the RTR to the meter. The shroud assembly is polycarbonate. The housing of the Pit ORION is constructed of a polycarbonate material. TEMPERATURE: The operating range of the RTR is -40C to 49C (-
40F to 120F). The operating range of the Pit ORION is -40C to 60C
(-40F to 140F). The water meter should not be subjected to tempera-
tures below freezing.

BadgerMeter,Inc. RTR-T-36 5-02 MOISTURE: The RTR is permanently sealed and designed for submerged meter pit applications. The RTR Pit ORION system is also designed for flooded or submerged meter pit locations. WIRE CONNECTIONS: The RTR can be factory prewired with pre-
sized wire harness of either 5 or 20 feet to the ORION Pit Module. ELECTRONICS: The piezoelectric switch circuit board is completely sealed against moisture inside the unit and sealed to ensure protection from humidity. The Pit ORION Module is designed to protect against the effects of humidity. ELECTRICAL: The electronic circuitry of the RTR and Pit ORION Module is designed to provide immunity to electrical surges and transients per IEC801-2, IEC801-4 Severity Level 4. OPERATING CHARACTERISTICS: The RTR has an output equal to 1/10th of the meter test circle with the characteristics of an open drain FET. The on-state condition is a solid-state switch closure. Off-state condition is an open circuit. Powered by an external source, the RTR has a maximum rating of 30 VDC at 1 mA (25C). PATENT: The Badger RTR Pit ORION application is covered by US patent number 5,298,894. TRANSPORTATION WARNING: The Federal Aviation Administration prohibits operating transmitters and receivers on all commercial aircraft. When powered, the Pit ORION Module is considered an operating transmitter and receiver and cannot be shipped by air.
