The Endress+Hauser Waterpilot FMX21 Hydrostatic Level Probe

The Waterpilot FMX21 HART transmitter with capacitive, oil-free ceramic measuring cell is typically used in the process and environmental applications for hydrostatic level measurement. The measuring ranges can be freely adjusted and a density-compensated level measurement can be activated. It is certified for drinking water and offers integrated temperature measurement. A robust design for applications in wastewaters and sludges or a metal-free version for usage in salt water is also available.
