The Pulsed Transmitter creates the signal that is picked up by the Acoustic Sensor.

The Pulsed Transmitter creates this signal by automatically opening and closing a Pulsed Water Valve, which allows water to alternately flow out of a pipe for a short period of time. This regular interruption of water flow creates pressure changes inside the water pipe that travel along the pipe as waves and cause slight motion in the walls of the water pipe.

The Acoustic Sensor picks up the sound generated by the pipe motion at the ground surface and provides a measure of the strength of the sound to the user. The user locates the underground pipe by finding the maximum (peak) signal level on the surface.

Pulsed Transmitters are connected to sprinkler heads, hose bibs, water meter bases, fire hydrants and clean-outs.

Pulsed Water Transmitters are supplied with

• Damper hose with On/OFF Valve
• Waste (run-off) hose
• Filter Washer (not shown in the image above)

Pulsed Water Valves are supplied with Imperial or Metric fittings depending on your region

Always flush any connection site until the water that flows are clear of all rust, silt, sealing compounds and foreign materials before connecting a Pulsed Transmitter Valve to the water line.

Always used the supplied filter washer to the inlet of the Pulsed Water Valve.

Check the filter washer screen (located inside the inlet of the Pulse Transmitter) for debris. Remove and clean if dirty. Replace filter washer if screen is damaged in any way.

NOTE: Water pipes must be full and pressurized. Optimum pressure range is between 3 and 7 bar.

WARNING: Always verify that your Pulsed Water Valve maximum pressure is within the pressure of the target water pipe, by checking the colored heat shrink band on its lead:

• Yellow: 4 bar max
• Red: 10 bar max
