Endress+Hauser’s Prosonic S ultrasonic transmitters offer outstanding performance at competitive prices. They’re the ideal way to accurately monitor a multitude of levels – all from a single transmitter!
Your instrumentation should fit around your plant; not the other way around. That's why the Prosonic S FMU90 has an excellent measuring range of up to 70m and offers continuous, non-contact level measurement of everything from fluids, pastes and sludge to powdery and coarse-grained bulk solids.

The straightforward, menu-guided operation (via its 6-line plain text display) means there are no codes to decipher - so you can focus on getting the job done. Even better, the envelope curves on the display allow you to see exactly what the instrument sees and Prosonic S delivers calculations in the form you need - as an average, difference or sum - so you can make the best possible use of your data.
Operation couldn't be simpler: just use the free operating software for reliable commissioning, maintenance and documentation of the measuring point. And, with HART and PROFIBUS DP connectivity, Prosonic S can be easily retrofitted into existing systems.
More measurement for your money
With the addition of the new Prosonic S FMU95 transmitter to the range, five sensors are now connectable as standard - but with the further possibility for ten sensor connections as an option - ideal for tank farm monitoring, grain silos and bunker level measurement. And to cap it all, the Prosonic S FMU95 boasts a fast scan-time, due to its facility to prioritise individual tanks or silos that have a high turnaround for extra attention.
