Product Description

Product Description

Endress+Hauser Prosonic FMU40 Ultrasonic Level Transmitter Advanced Non-Contact Measurement for Liquids and Solids
1. Introduction
The Prosonic FMU40 is a compact, high-precision ultrasonic transmitter from Endress+Hauser, designed for non-contact continuous level measurement of liquids, pastes, slurries, and coarse bulk solids. It also supports flow measurement in open channels and weirs. As part of E+H's FLEX Extended selection, it balances technica excellence with process optimization capabilities, targeting industries like chemicals, water/wastewater, and bulk material handling .

2. Measurement Principle
The FMU40 operates on Time-of-Flight (ToF) ultrasonic technology:
Ultrasonic pulses emitted by the sensor reflect off the material surface.
Distance calculation: Based on the pulse travel time and speed of sound in the medium.
Integrated temperature sensor: Automatically corrects sound velocity changes due to temperature variations (±0.3% accuracy).
Envelope curve analysis: Visualizes echo profiles on the display for real-time diagnostics and optimization .

Parameter	Specification
Measuring Range	Liquids: 0.25-5 m (0.8-16 ft); Solids: 0.25-2 m (0.8-6.6 ft)
Blocking Distance	0.25 m (0.8 ft) for all media
Process Temperature	-40°C to +80°C (-40°F to +176°F)
