Typically used in the process and environmental applications for hydrostatic level measurement


Hydrostatic cable-mounted level sensor for clean water, wastewater and saltwater applications.

Waterpilot FMX21 is a robust 2-wire hydrostatic level sensor that comes in three versions to suit a wide range of applications which include the measurement of groundwater, wastewater and saltwater. It is also available with an integrated temperature transmitter as an additional measurement point. Waterpilot offers a variety of measuring ranges, configurable using HART protocol, and its potted electronics and double breather tube filters make it highly resistant to environmental conditions for reliable results, time after time.
