The WL420 submersible hydrostatic level transmitter was designed for continuous monitoring of liquid level in wells, reservoirs, tanks, boreholes, rivers and more.
The submersible unit senses the hydrostatic pressure at the bottom of the liquid and transmits a current signal proportional to the water column to the upstream instrumentation.
The highly stable 316L stainless steel diaphragm sensor is fully compatible with raw or chlorinated water and most semi-aggressive liquids and oils.
With a special vented cable to equalize changes in atmospheric pressure, it accurately transmits the measured liquid level. The cable length, which depends on the application and the desired reach, can be set at the time of purchase or adapted in the application from the standard lengths.
Several level measuring ranges are available for a wide variety of applications, allowing use with local or remote indicators, data loggers or PLCs.
