Technical Characteristics and Field Versatility
-
Advanced Diagnostics: The FMU40 features a four-line plain text display capable of showing the envelope curve. This allows for sophisticated on-site echo analysis to identify and suppress interference from tank internals or agitator blades.
-
Flexible Power Options: Available in both two-wire and four-wire configurations, it can be easily integrated into standard 4 to 20 mA loops or powered independently for applications requiring higher signal strength.
-
Chemical Resilience: The sensor is constructed from chemically resistant PVDF and is hermetically sealed and potted. This protects the internal transducer from corrosive vapors and ensures a long service life in harsh chemical environments.
-
Simple Commissioning: With its menu-guided operation and “calibration without filling” capability, the FMU40 can be set up in minutes. The user simply enters the empty and full distances to define the measuring span.
-
Integrated Temperature Compensation: An internal temperature sensor corrects the Time-of-Flight calculation in real-time, maintaining high accuracy even as the air temperature in the vessel or environment changes.
