Brand new and original Endress+Hauser FMU40-RRH3A2 Prosonic FMU40 Ultrasonic Level Sensor 4-20mA HART are sold with a competitive price in our wabsite.

Product Details: 

The Endress+Hauser Prosonic FMU Series is a non-contact ultrasonic level measurement solution designed for continuous level monitoring of liquids, slurries, pastes, and bulk solids. It is widely used in storage tanks, open channels, wastewater treatment plants, silos, and chemical vessels. The ultrasonic sensor uses time-of-flight technology for stable measurement up to 5 meters for liquids and 2 meters for solids. Integrated temperature compensation ensures reliable accuracy under changing ambient conditions. PVDF wetted parts offer strong chemical resistance, making it ideal for corrosive media environments. Supports 4–20mA HART communication for easy integration into DCS and PLC systems. 

Core Product Principle：

The Prosonic FMU series uses ultrasonic Time-of-Flight technology.

The sensor emits ultrasonic pulses toward the media surface and calculates the distance by measuring the return echo time.

This enables:

• stable non-contact measurement

• no direct media contact

• low maintenance

• long service life

This is especially popular among overseas industrial buyers because there are no moving parts and almost zero wear.
