Endress+Hauser Prosonic M FMU43 Ultrasonic Level Transmitter

The Endress+Hauser Prosonic M FMU43 Ultrasonic Level Transmitter provides reliable non-contact level and volume measurement for open channels, water tanks, and silos across Saudi Arabia's water utilities, food processing, and building service applications. With a measurement range up to 15 meters and beam angle of 12°, the FMU43 suits the large-diameter water storage reservoirs operated by NWC in Saudi cities and the open concrete channels of Riyadh's Wadi Hanifah water harvesting infrastructure. The non-contact measurement principle eliminates maintenance contact with Saudi Arabia's municipal water systems where physical contact would require full decontamination procedures.

The FMU43's integrated temperature compensation corrects ultrasonic velocity for the ambient temperature variations encountered at NWC's outdoor water reservoirs — from summer heat of 50°C at Jubail coastal tanks to winter cold of 5°C at Tabuk northern water storage facilities. The transmitter's built-in linearization tables convert level measurement to volume for non-standard vessel geometries including the conical base tanks common in Saudi Aramco's produced water collection pits. Integrated display and keypad allow local commissioning and calibration without handheld devices, beneficial for NWC maintenance technicians working in remote Saudi water network infrastructure.

The FMU43's flow measurement capability using standard flume and weir linearization curves enables open channel flow measurement in Saudi Arabia's agricultural irrigation canals in Qassim and Al-Ahsa, providing data for Saudi Ministry of Environment, Water and Agriculture's irrigation water allocation management. The transmitter's relay outputs provide high-level alarm and low-level pump control signals for NWC's unmanned remote pumping station automatic control without SCADA connectivity. The transmitter's IP68 rating and housing sealed to IP68 standard withstand Saudi Arabia's seasonal flooding in low-lying wadi areas.

Razz Middle East provides FMU43 transmitters for NWC, Marafiq, and Saudi Aramco utility water applications with standard 2-year warranty and optional maintenance contracts. Our field service team provides on-site commissioning including temperature sensor calibration, blanking distance setup for foam-free Saudi wastewater applications, and pump control relay testing.
