The FMU30 is intended only for standard water treatment and has no HART output. If HART output and corrosion resistance are required, use the FMU40 for a 5 m range, the FMU41 for an 8 m range and the FMU42 for a 10 m range.
The FMU30 is used in wastewater treatment plants, for process water tank loading, and for level monitoring of storage and buffer tanks. The FMU30 provides proven software algorithms and a four-line plain text display of warning and alarm messages, ensuring fast fault response. The display also shows the envelope curve, presenting the analysis results directly on site for fast and accurate fault diagnosis.
Benefits
Four-line plain text display with menu-guided on-site operation for fast, simple instrument commissioning, available in 7 languages
On-site envelope curve display for simple instrument fault diagnosis
Linearization function (up to 32 points) converts the measured value into length, volume or flow in any unit
Non-contact measurement, minimizing maintenance
Can be installed from thread G1½ or 1½ NPT upwards
Built-in temperature sensor for automatic correction of the temperature-dependent speed of sound
Application areas
For continuous, non-contact level measurement of liquids, pastes, sludge and bulk solids; system integration: 4...20 mA; maximum measuring range: 1½ sensor: liquids: 5 m (16 ft); solids: 2 m (6.6 ft); 2" sensor: liquids 8 m, solids: 3.5 m (11 ft)
Commonly used models:FMU30-AAHEABGHF 8 m and FMU30-AAHEAAGGF 5 m
