Endress+Hauser Prosonic FMU40: Non-Contact Ultrasonic Level Measurement
Reliable level information helps operators manage storage, prevent overfilling and plan maintenance. The Prosonic FMU40 uses ultrasonic time-of-flight measurement to monitor the product surface without direct sensor contact.
APPLICATION FOCUS
FMU40 is designed for level measurement in liquids, pastes and coarse bulk materials. It can also support flow measurement in open channels and at measuring weirs. Its compact design makes it a practical option for suitable tanks, sumps and process vessels.
KEY TECHNICAL HIGHLIGHTS
• Maximum measuring distance: 5 m for liquids and 2 m for solids
• Accuracy: ±2 mm or ±0.2% of the set measuring range
• Process temperature: -40 to +80 °C
• Process pressure: 0.7 to 3 bar absolute
• Main wetted material: PVDF
SELECTING FMU40 FOR YOUR APPLICATION
Successful ultrasonic measurement starts with a clear view of the product surface. Review the mounting position, nozzle dimensions and blocking distance before installation. Foam, turbulence, dust and obstructions can affect the returning echo, so the measuring range should be assessed against actual operating conditions. Temperature, pressure and material compatibility must also be checked for the selected device configuration.
For a replacement enquiry, provide the complete existing order code and nameplate information. For a new installation, send the medium, measuring range, vessel dimensions, process temperature, pressure, required output and approval requirements. These details help confirm the appropriate configuration before ordering.
