LEVEL INSTRUMENTS

Micropilot FMR10 offers continuous non-contact level measurement and is a perfect application fit for the water & wastewater industry and utilities across all industries. FMR10 belongs to the first radars with Bluetooth® commissioning, operation and maintenance app. Signal curves can be shown via app on every Bluetooth®-enabled smartphone or tablet (iOS, Android). With the compact design, thanks to unique chip, the device is ideal for limited space applications.

Radar for continuous level measurement in liquids. For use in storage tanks, open basins, pump/lift stations or sewer management.

Product Overview
The LSVR is a vibrating rod point level switch designed for solids and powders. It is widely used across industries such as cement, PVC, coal, steel, food grains, fly ash, and chemicals. The device is a single-element, mechanically tuned sensor that provides reliable level detection without requiring calibration.

Operating Principle

• A piezoelectric crystal excites the vibrating rod at its natural resonance.
   
• In free air, the rod vibrates at full amplitude.
   
• When in contact with bulk material, resonance is disturbed, causing amplitude drop.
   
• The electronics detect this change, triggering a switching output to indicate material presence.

✅ In short: The Trumen LSVR is a rugged, reliable, and calibration-free vibrating rod switch for bulk solid level detection, offering wide industry applicability, high safety certifications, and flexible mounting/electrical options, making it a strong solution for demanding process environments.

Micropilot FMR62B is part of the new generation of 80 GHz radar sensors. It is used for continuous non-contact level measurement in challenging liquid applications. It masters process requirements like high temperatures, high process pressure as well as changing media. Testing concepts for SIL-locking and proof tests reduces the risk of systematic errors. Heartbeat Technology offers verification and monitoring functions to identify anomalies for increased safety and productivity.

The Micropilot FMR62B is suitable for free-space applications up to 80m and offers high beam focusing for vessels with many internal fittings.

 The Prosonic FMU44 sensor is suited for non-contact level measurement in fluids, pastes, coarse bulk material and flow measurement in open channels or at weirs. The two-wire or four-wire compact transmitter can be used in applications with storage tanks, agitators, on stockpiles and conveyor belts. The envelope curve can be shown on the on-site display for simple diagnosis. Linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume or flow rate.
