To install the Dynasonics RS-900w Polymer Ultrasonic Flow Meter, follow these steps:
1. Depressurize, vent, and drain the piping system before installation or maintenance of the flow meter.
2. Ensure that the flow meter arrow faces the direction of flow.
3. Apply Teflon tape to the threads on the pipe and xxxx the pipe into the flow meter. Do not overtighten.
4. Disconnect the power from the flow meter source and/or receiving device before installation or maintenance. The flow meter source and/or receiving device must provide basic isolation from mains for safe operation.
5. Use watertight connectors/gel caps to connect the wire leads from the RS-900w flow meter to a 2-conductor shielded 20 AWG (or larger) copper wire.
6. Route the cable from the RS-900w flow meter to the irrigation controller or a Badger Meter flow monitor/endpoint. The cable can be extended up to 2000 feet.
7. When connecting to an irrigation controller or Badger Meter flow monitor/endpoint, locate the section of the terminal strip on the monitor labeled SENSOR INPUT or SENSOR. Connect the red (or white) wire to IN, SIGNAL (+), or SIGNAL terminal, and connect the black wire to GND, SIGNAL (-), or COM terminal.
8. When interfacing with other equipment, consult the equipment manufacturer for input designations.
9. After all electrical connections have been made, turn on power at the irrigation controller or a Badger Meter flow monitor/endpoint.
Please refer to the "Installation" section of the user manual for more detailed instructions and safety precautions.
