Global Water's WL400 Water Level Sensor provides highly accurate water level measurement for a wide variety of applications, including those in severe environments.  The submersible pressure transducers have a dynamic temperature compensation system, enabling high accuracy measurements over a wide temperature range.  The water level sensor is easily adapted to all dataloggers, telemetry, monitoring equipment, and displays.

Each of the water level sensors consist of a solid state submersible pressure transducer encapsulated in a stainless steel 13/16 inch diameter housing.  The water level sensor has a molded-on waterproof cable and a two-wire 4-20 mA high level output for connection to a monitoring device.  A 25 ft cable is standard, and optional cable lengths are available up to 500 ft.
