Prosonic S for open channels and weirs

Endress+Hauser’s Prosonic S FMU90 ultrasonic transmitter and associated sensors have been specially designed for flowmetering in open channels and weirs. They’re the cost-effective flow solution for applications in the water, wastewater and environmental industries.

Non-contact and maintenance-free, Prosonic S provides reliable flow measurement in open channels and weirs using one or two ultrasonic sensors. Using a single sensor in conjunction with built-in linearisation tables (including BS3680) or application-specific tables programmed via a 32-point table or formula, Prosonic S will simultaneously measure both level and flow.

The addition of a second sensor allows backwater to be detected, preventing the problems associated with erroneous readings. What’s more, with two sensors Prosonic S can be used for pump or screen control using pre-programmed routines. A range of relays, pump control functions and test functions are also available to further enhance capabilities. Have your information how you want it: the Prosonic S transmitter will also quickly perform average, difference and sum calculations so you get the exact data you require.
