FMR50 Radar Level Transmitter Overview
FMR50 is a radar level transmitter used for continuous measurement of liquid, slurry, and solid levels. It uses 80GHz frequency-modulated continuous wave technology and features a small beam angle and strong anti-interference capability, making it suitable for industries such as chemicals, water treatment, and food.
The instrument supports communication protocols such as 4~20mA HART, PROFIBUS PA, and Modbus, and can be seamlessly integrated into existing control systems.
Core Technical Parameters
The table below lists the key performance indicators of the FMR50 for selection and procurement reference.
| Parameter | Typical Value/Range | Description |
|---|---|---|
| Measurement Principle | 80GHz FMCW Radar | Non-contact continuous measurement |
| Measuring Range | 0~30m (liquid) | Depends on medium and antenna |
| Accuracy | ±2mm | Under standard working conditions |
| Process Temperature | -40~+200℃ | With high-temperature extension |
| Process Pressure | -1~+40bar | Depends on process connection |
| Output Signal | 4~20mA/HART | Optional PROFIBUS PA |
| Protection Class | IP66/IP67 | Standard configuration |
Installation and Commissioning Steps
Installation Precautions
- Avoid installation directly above the feed inlet to prevent false echoes.
- The antenna should extend out of the mounting nozzle to ensure the beam is not obstructed.
- For solid level measurement, it is recommended to use a universal joint to adjust the antenna angle.
- Ensure the process connection is reliably sealed and the pressure rating matches the working conditions.
Commissioning Process
- After power-on, connect the instrument via the display module or commissioning software.
- Enter medium characteristics (dielectric constant, vessel shape) to optimize signal processing.
- Set empty tank calibration and full tank calibration to establish the reference zero point.
- Use the echo curve graph to suppress fixed interference echoes.
- Verify that the output current is consistent with the host computer display.
Common Faults and Handling
The FMR50 has a self-diagnosis function. When an abnormality occurs, the problem can be quickly located through the diagnostic code. The following are typical faults and countermeasures:
- Measurement value jumps: Check whether the antenna is scaled, clean it, or adjust the suppression curve.
- No echo signal: Confirm whether the medium dielectric constant is too low, or the installation position is improper.
- Abnormal current output: Check the supply voltage and loop load resistance.
- Communication interruption: Check the bus address and terminal resistance settings.
If the fault cannot be eliminated, please refer to the detailed fault tree in the FMR50 Chinese manual, or contact the manufacturer's technical support.
Selection and Procurement Recommendations
When purchasing the FMR50, please specify the process connection type, antenna material, sealing material, and communication protocol. For corrosive media, it is recommended to use PTFE or ceramic antennas; for high-temperature and high-pressure working conditions, confirm whether the process temperature and pressure are within the allowable range.
Correct selection can extend the instrument's service life and reduce maintenance costs. It is recommended to also download the FMR50 Chinese manual as a reference for installation and maintenance.
