Compact Ultrasonic Level Transmitter Prosonic FMU41
- SKU:
- Compact Ultrasonic Level Transmitter Prosonic FMU41 series
- Weight:
- 0.00 Grams
Description
Application
The Prosonic FMU41 is designed for non-contact level measurement in liquids, pastes, coarse bulk materials, and for flow measurement in open channels or at weirs. This versatile compact transmitter, available in two-wire or four-wire configurations, is ideal for use in storage tanks, with agitators, on stockpiles, and conveyor belts. It features an on-site display that can show the envelope curve for straightforward diagnostics. Additionally, it includes a linearization function (up to 32 points) that allows for conversion of the measured values into any desired unit of length, volume, or flow rate.
- Configuration: Two-wire or four-wire setup for continuous, non-contact level and flow measurement.
- Process Connection: Threaded
- Temperature Range: -40 to +80°C (-40 to +176°F)
- Pressure Range: +0.7 to +3 bar (+10 to +44 psi)
- Maximum Measuring Distance: 8m (26ft) for liquids, 3.5m (11ft) for solids
- Blocking Distance: 0.35m (1.15ft) for both liquids and solids
- Certifications: International explosion protection certificates
Benefits
- Dependable Non-Contact Measurement: Ensures accurate readings without physical contact with the medium.
- Easy Setup and Operation: Quick commissioning through a user-friendly, menu-guided on-site interface with a four-line plain text display available in seven languages.
- Diagnostic Capabilities: On-site display of envelope curves for straightforward diagnostics.
- Robust Design: Features a hermetically sealed and potted sensor made from chemically resistant PVDF material.
- Simplified Calibration: Allows calibration without the need to fill or empty the vessel.
- Integrated Temperature Sensor: Automatic correction of temperature-dependent sound velocity ensures consistent accuracy.
