The submersible hydrostatic level transmitter WL420 has been designed for continuous liquid level monitoring for a wide range of applications. The highly stable 316L stainless steel diaphragm sensor is fully compatible to raw or chlorinated water and most semi-aggressive liquids. The device measures the static pressure of the liquid column above the transmitter and transmits a current signal proportional to the water column to the instrumentation above. Supplied with a special vented cable to compensate the atmospheric pressure changes, it accurately transmits the measured liquid level. The application-dependent cable length can be defined at the time of purchase to the desired extent and can also be customer adapted at the application site.
