Endress+Hauser FMX21-AA121HGD10A Level measurement, Endress+Hauser Waterpilot FMX21. Three different versions of pressure sensor for drinking water, wastewater and sewage, and salt water.
The Endress+Hauser Waterpilot FMX21 level transmitter features a capacitive, oil-free ceramic measuring cell, and is typically used in process and environmental applications for hydrostatic level measurement. With HART output, the measuring ranges can be freely adjusted, and a density-compensated level measurement can be activated. The FMX21 is certified for drinking water and offers integrated temperature measurement.
