Endress+Hauser Prosonic FMU41
Ultrasonic Level Measurement for Tanks and Open Channels
From storage vessels to open-channel monitoring, dependable level information helps operators manage inventory and make timely operating decisions. The Prosonic FMU41 provides continuous measurement without placing a probe in the product.
A COMPACT SOLUTION WITH GREATER REACH
The FMU41 uses ultrasonic time-of-flight technology for liquids, pastes and coarse bulk materials. It also supports flow measurement in open channels or at weirs. Maximum measuring distances are 8 m for liquids and 3.5 m for solids, with a 0.35 m blocking distance. Actual usable range depends on the installation and surface conditions.
TECHNICAL HIGHLIGHTS
• Maximum distance: liquids 8 m; solids 3.5 m
• Blocking distance: 0.35 m
• Process temperature: -40 to +80 °C
• Process pressure: 0.7 to 3 bar absolute
• Main wetted material: PVDF
• Threaded process connection; two-wire or four-wire versions
PRACTICAL DIAGNOSTICS AND FLEXIBLE OUTPUT VALUES
The on-site display can show the echo envelope curve to assist diagnosis. A linearization function with up to 32 points converts the measurement into length, volume or flow values. The required electronics and communication configuration should be confirmed against the complete order code.
WHAT TO CHECK BEFORE ORDERING
For tank service, review the mounting position, nozzle dimensions, internal obstructions and expected highest level. Keep the product surface outside the blocking distance. Foam, agitation, vapour and dust can influence echo quality, so application assessment should use real operating conditions rather than nominal tank height alone.
For open-channel or weir applications, provide the channel geometry, measuring arrangement and required flow range. When replacing an installed device, send the existing nameplate and complete order code to help check mechanical, electrical and approval requirements.
