The Netafim pressure-indicator flag provides a visible operating check for drip irrigation. The flag lifts as pressure builds in the connected line, making it useful where the dripline is covered by mulch or soil.
At zero pressure the flag lies down. It is partly raised at approximately 30kPa and upright at approximately 50kPa. These positions show the pressure response without requiring a numerical gauge reading.
The assembly includes the indicator body and flag, 90cm of 3x5mm micro tube, a start connector and a 33cm plastic stake. Connect the feedtube to the irrigation line and place the stake where the flag is visible. The manufacturer recommends monitoring a low-pressure point in the system.
