- Model FMU30 - Ultrasonic Sensor



The range of applications extends from monitoring levels in sewage treatment plants and process water tanks to applications for loading, storage and buffer tanks. FMU30 ultrasonic sensor offers proven software algorithms and all warning and alarm messages are shown on the four-line plain text display and guarantee fast remedy of problems. The envelope curve can also be shown on the display. As the analysis results are displayed directly on-site, this ensures quick and accurate error diagnostics. Cost effective all-round instrument for level applications in liquids and bulk solids.

  • Quick and simple commissioning via menu-guided onsite operation with four-line plain text display, 7 languages selectable
  • Envelope curves on the on-site display for simple diagnosis
  • Linearization function (up to 32 points) for conversion of the measured value into any unit of length, volume or flow rate
  • Non-contact measurement method minimizes service requirements
  • Installation possible from thread G 1½ or 1½ NPT upwards
  • Integrated temperature sensor for automatic correction of the temperature dependent sound velocity

Two-wire instrument for continuous non-contact level and flow measurement.
