Installation and Commissioning Points
Installation Precautions
- Ensure the antenna axis is perpendicular to the material surface and avoid installation directly above the feed inlet.
- For liquid measurement, it is recommended to use a lens antenna or horn antenna, and keep the distance between the antenna end and the highest level not less than the blind zone.
- In working conditions with stirring or foam, a still pipe or bypass pipe installation method should be selected.
- Avoid installation near obstacles in the tank (such as heating coils, baffles) to prevent false echoes.
Commissioning Steps
- Connect the instrument via a HART handheld communicator or Endress+Hauser's FieldCare/DeviceCare software.
- Set the empty tank calibration (E point) and full tank calibration (F point).
- Select the dielectric constant range according to the medium characteristics and enable the echo suppression function.
- Check the echo curve to confirm that the main echo is at the expected position and its amplitude is stable.
- Save the parameters and record the commissioning report.
Common Problems and Selection Recommendations
Common Problems
- Fluctuating measured value: Check whether the antenna is scaled, or whether the medium generates foam or steam.
- Signal loss: Confirm whether the supply voltage and loop resistance are within the allowable range.
- False echoes: Use the echo suppression curve to eliminate fixed interference.
Selection Recommendations
- For high-temperature and high-pressure conditions, choose the version with a high-temperature isolation flange.
- For corrosive media, choose a PTFE or ceramic sealed antenna.
- For sanitary applications, choose 3-A or EHEDG certified clamp connections.
Summary
With its 80 GHz technology, high accuracy, and rich communication interfaces, the FMR67B radar level transmitter has become a reliable choice for industrial level measurement. Correctly downloading and reading the Chinese manual, combined with the parameter analysis and installation recommendations in this article, can significantly improve commissioning efficiency and measurement stability.
