Technical Characteristics and On-Site Intelligence
-
Integrated Time-of-Flight Technology: The device measures the distance to the medium surface using ultrasonic pulses. It features an integrated temperature sensor that automatically compensates for changes in the speed of sound, ensuring measurement stability even when ambient temperatures fluctuate.
-
On-Site Diagnostics & Display: The FMU30 features a four-line plain text display that allows for quick commissioning without external tools. Uniquely for its class, it can display the envelope curve directly on-site, enabling technicians to visually confirm signal quality and troubleshoot echoes caused by tank internal obstructions.
-
Versatile Linearization: The device includes a 32-point linearization table. This allows the measured distance to be converted into specific units of volume (e.g., liters, gallons) for irregularly shaped tanks or into flow rates for open channels and weirs.
-
Non-Contact & Maintenance-Free: Because the sensor never touches the medium, it is not subject to corrosion, coating, or mechanical wear. This significantly reduces the total cost of ownership compared to contact-based methods.
-
Two-Wire Simplified Wiring: Operating on a standard 4 to 20 mA two-wire loop, the FMU30 is easy to integrate into existing control systems and requires minimal cabling infrastructure.
