Site Assessment
Straight pipe installation requirement: 10 x diameter pipe upstream (before the meter) and 5 x diameter pipe
downstream (after the meter).
The meter may be installed in any position. For non-horizontal positions, the flow should be upwards.
Prior to installation of the meter, the pipeline should be thoroughly flushed.
Meter must be installed so that the pipe will be full of water at all times during metering.
Recommendation: Continuous Acting Air Vents of proper size and type be installed to eliminate air.
Pulse Output Connections
Meter Pulse Output Port:
A Netafim IRT Series meter has 3 different register types:
Standard Register (pulse output capable)
Photo Diode Register (voltage output)
Multi-Purpose Electronic (MPE) Register
The same register fits into all the Netafim mechanial meter types (M Series, WMR Series, WST/WT Series, IRT Series)
Electrical Connections
Standard Register (pulse output capable)
A "Pulse Reed Switch" module must be installed onto the register to get pulse output.
