Waterpilot FMX167

Reliable and rugged level probe with ceramic measuring cell
compact device for level measurement in fresh water, wastewater and saltwater

Areas of application

The Waterpilot FMX167 is a pressure sensor for hydrostatic level measurement. Three versions are available at Endress+Hauser:


	FMX167 with an outer diameter = 22 mm (0.87 in): Version very suitable for drinking water applications and for use in probe tubes with small diameters
	FMX167 with an outer diameter = 42 mm (1.66 in): Heavy version and very easy to clean thanks to the flush-mounted diaphragm. Very suitable for wastewater and sewage treatment plants
	FMX167 with an outer diameter = 29 mm (1.15 in): Resistant version for use in saltwater and very suitable for applications on ships (e.g. ballast water tanks)
