FMR30B Radar Level Transmitter Product Overview
FMR30B is a high-frequency radar level transmitter, suitable for continuous level measurement of liquids, slurries, and granular solids. It uses frequency modulated continuous wave (FMCW) technology and features high precision and low maintenance.
This instrument is widely used in chemical, water treatment, petroleum, and food industries, and can handle high-temperature, high-pressure, and corrosive conditions.
Core Advantages
- High-precision measurement: resolution up to ±1mm, meeting strict process control requirements.
- Non-contact measurement: not affected by changes in medium density or viscosity.
- Strong anti-interference capability: adopts 80GHz high-frequency technology with a small beam angle, suitable for narrow spaces.
- Multiple outputs: supports 4-20mA HART, Modbus RTU, and other communication protocols.
Technical Parameters and Model Selection
Before selecting a model, please confirm the process connection, antenna material, and power supply method. The following are the main technical parameters of the FMR30B.

| Protection class | IP67 / IP68 |
Installation and Commissioning Steps
Correct installation is the prerequisite for ensuring measurement accuracy. Please follow the steps below.
- Determine the installation position: avoid the feed inlet, agitator, and tank wall, and keep at least 200mm away from the tank wall.
- Install the flange or thread: ensure the antenna is perpendicular to the medium surface and avoid tilting.
- Electrical connection: connect the power and signal cables according to the wiring diagram in the manual, and pay attention to grounding the shielding layer.
- Parameter setting: set the range, medium characteristics, etc. via the HART communicator or host computer.
- Echo curve analysis: use the commissioning software to observe the echo and adjust interference suppression if necessary.
Common Issues and Maintenance
Measurement value fluctuation or jumping
- Check whether the antenna has scaling or condensation, and clean the antenna surface.
- Confirm whether the installation position generates false echoes; you can adjust the installation angle or enable interference suppression.
- Check whether the power supply voltage is stable, and avoid sharing the power supply with a frequency converter.
No signal output
- Check whether the wiring polarity is correct and whether the fuse is blown.
- Confirm whether the range setting covers the actual level.
- If there is still no output, contact the manufacturer's technical support.
Summary
With 80GHz high-frequency technology and a rugged design, the FMR30B radar level transmitter provides a reliable solution for industrial level measurement.
