E+H FMU40 Ultrasonic Level Transmitter
FMU40-ARB2A2
The FMU40 Ultrasonic Level Transmitter is an advanced non-contact measurement solution specifically engineered for continuous liquid level monitoring and open channel flow measurement in demanding industrial environments. Featuring a compact PVDF sensor body with a 5-meter liquid measuring range and smart interference signal filtering, it delivers millimeter-level precision without physical contact with the media. Equipped with 4-20mA HART, PROFIBUS PA, and FOUNDATION Fieldbus communication protocols alongside an IP68 weatherproof enclosure, this versatile transmitter ensures long-term, maintenance-free performance across water treatment plants, chemical storage facilities, and utility management systems.
The FMU40 Ultrasonic Level Transmitter represents a highly reliable and cost-effective approach to non-contact level and volume measurement across a vast spectrum of industrial processing applications. Operating on the proven Time-of-Flight principle, the instrument emits high-frequency acoustic pulses that reflect off the target surface and return to the transducer, allowing integrated microprocessors to convert signal transit time into accurate, real-time height or volumetric flow calculations.
Its robust design incorporates automated temperature compensation mechanisms to neutralize ambient thermal shifts, while proprietary envelope curve algorithms continuously identify and filter out false echo signals caused by agitators, internal tank struts, or surface foam. Constructed with chemically resistant PVDF wetted parts and a ruggedized IP68 housing, the unit withstands aggressive chemical vapors, outdoor weather exposures, and high-humidity washdowns without compromising measuring accuracy.
Designed for seamless integration into modern industrial control networks, the FMU40 offers flexible fieldbus output options and intuitive local menu navigation via a backlit LCD display, making it an indispensable asset for engineers seeking to minimize maintenance downtimes and optimize process control efficiency.
FAQ
Q1: What is the blocking distance (dead zone) of the FMU40 level sensor?
A: The FMU40 has a minimum blocking distance of 0.25 m (0.8 ft). Level measurement cannot take place within this zone directly below the sensor membrane.
Q2: Can the FMU40 be installed outdoors or in high-humidity environments?
A: Yes. The device features an IP68 / NEMA 6P rugged housing with weather-resistant materials, making it ideal for outdoor open-channel flow monitoring and harsh industrial plant environments.
Q3: How does the sensor perform with turbulent or agitated liquid surfaces?
A: The FMU40 uses advanced echo-tracking algorithms and configurable damping settings to filter out surface turbulence and provide a stable 4–20 mA output.
Q4: Do you offer OEM/ODM customization and private label options for global distributors?
A: Yes, as an established manufacturer, we offer customized process connections, logo labeling, custom enclosure colors, and pre-calibrated parameter setups for OEM partners and B2B buyers worldwide.
