Prosonic FMU43 is suitable for non-contact level measurement of liquids, pastes and bulk solids as well as flow measurement in open channels or measuring weirs. The two-wire or four-wire compact transmitter can be used for level measurement under demanding conditions in storage tanks, mixers, silos and on conveyor belts. The on-site envelope curve display enables simple device fault diagnostics. 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 and simple device commissioning, available in 7 languages
On-site envelope curve display for simple device fault diagnostics
FieldCare operating software allows convenient remote operation, fault diagnostics 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
Integrated temperature sensor automatically corrects the temperature-dependent speed of sound
Optional remote display and operation (max. installation distance from the transmitter up to 20 m (66 ft))
Application
Suitable 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, FF Foundation Fieldbus; maximum measuring range: liquid: 5 m, solid: 2 m. Other measuring ranges: FMU41: liquid 8 m, solid 3.5 m; FMU42: liquid 10 m, solid 5 m; FMU43: liquid 15 m, solid 7 m; FMU44: liquid 20 m, solid 10 m
