The Prosonic FMU42 is used for non-contact level measurement of liquids, pastes and coarse bulk solids as well as for flow measurement in open channels or weirs. The two-wire or four-wire compact transmitter can be used in demanding conditions such as storage tanks, agitators, silos and conveyor belts. On-site envelope curve display enables simple instrument fault diagnosis. The linearization function (up to 32 points) converts the measured value into length, volume or flow in any unit.
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
The FieldCare operating software allows convenient remote operation, fault diagnosis and measuring point documentation
Suitable for hazardous areas (gas Ex, dust Ex)
Linearization function (up to 32 points) converts the measured value into length, volume or flow in any unit
Built-in temperature sensor for automatic correction of the temperature-dependent speed of sound
Optional remote display and operation (maximum installation distance from the transmitter of 20 m (66 ft))
Application areas
For continuous, non-contact level measurement of liquids, pastes, sludge and bulk solids; flow measurement in open channels and measuring weirs; system integration: HART (standard), 4…20 mA, PROFIBUS PA, FOUNDATION Fieldbus; maximum measuring range: liquids: 5 m, solids: 2 m. Other measuring ranges: FMU41: liquids 8 m, solids: 3.5 m; FMU42: liquids: 10 m, solids: 5 m; FMU43: liquids: 15 m, solids: 7 m; FMU44: liquids 20 m, solids: 10 m
