Hydro Services WLT420 Wireless Level Transmitter

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The Wireless Level Transmitter’s primary purpose is to periodically measure a 4-20mA transducer, and to wirelessly transmit the measurement to a different location and reproduce the 4-20mA signal. This is done with a very low power consumption (typically 150uA while asleep) which makes it ideal for remote sites where long battery life is important. The receiver also has an LCD to display the water level, current measurement and other parameters.
