FMR52 Product Overview
FMR52 is a radar instrument used for continuous level measurement, suitable for liquids, slurries, and bulk solids. Its non-contact measurement method makes it widely used in industries such as chemicals, water treatment, and food.
The instrument uses 80GHz high-frequency radar technology, with a small beam angle and strong anti-interference capability, enabling stable measurement even in small tanks or complex working conditions.
Core Advantages
- High precision: Measurement error can be controlled within ±2mm
- Strong anti-interference: Not affected by steam, dust, or foam
- Maintenance-free: Non-contact measurement, no wearing parts
- Wide range: Maximum measuring range up to 30 meters
Technical Parameters and Selection
Before selection, it is necessary to confirm the process connection, power supply, output signal, and environmental conditions. The following are the main parameters of FMR52 for reference by engineering technicians and procurement personnel.
Key Parameter Table
| Parameter | Specification |
|---|---|
| Measuring principle | 80GHz frequency modulated continuous wave radar |
| Measuring range | 0.2~30 meters (depending on antenna and medium) |
| Accuracy | ±2mm |
| Process connection | G1½, NPT1½, flange (optional) |
| Process temperature | -40~+200°C |
| Process pressure | -1~+40 bar |
| Output signal | 4~20mA/HART, PROFIBUS PA, Modbus |
| Power supply | Two-wire: 16~36V DC; Four-wire: 90~253V AC |
| Protection class | IP66/IP67 (optional IP68) |
Selection Notes
- Medium dielectric constant: Low dielectric constant media require a stilling well or lens antenna
- Process connection: Choose thread or flange according to the tank interface
- Output protocol: Must match the control system
- Explosion-proof certification: Intrinsically safe or flameproof type is required for explosive environments
Installation Steps
Correct installation is the prerequisite for ensuring measurement accuracy. Please follow the steps below and refer to the detailed dimensional drawings in the FMR52 Chinese manual.
Installation Process
- Confirm the installation position: Avoid interference sources such as feed inlets and agitators
- Weld or screw in the process connection: Ensure good sealing
- Adjust the antenna direction: Make the antenna perpendicular to the medium surface
- Connect the cable: Connect the power and signal wires according to the wiring diagram
- Tighten the housing: Ensure the protection class
Installation Precautions
- The antenna should extend out of the installation nozzle to avoid false echoes
- If there is an agitator in the tank, it is recommended to install a stilling well
- Avoid installing in the center of the tank to prevent multiple echoes
Commissioning and Operation
FMR52 supports local display and remote commissioning. Configuration can be completed quickly via a HART communicator or commissioning software.
Commissioning Points
- Empty tank calibration: Ensure the zero point is accurate
- Full tank calibration: Set the current corresponding to the full scale
- Echo curve: Use the echo curve to judge interference
- False echo suppression: Store interfering echoes
Common Faults and Handling
The following lists possible faults encountered during the use of FMR52 and troubleshooting methods. For more details, please refer to the FMR52 Chinese manual.
Troubleshooting Table
| Symptom | Possible Cause | Handling Measure |
|---|---|---|
| No display | Power supply error or cable break | Check power supply and wiring |
| Measured value fluctuates | Medium fluctuation or interference echo | Adjust installation position or suppress false echoes |
| Measured value is fixed | Antenna scaling or blockage | Clean the antenna |
| Output current exceeds limit | Incorrect range setting | Recalibrate |
Maintenance and Care
FMR52 has no moving parts, so daily maintenance is minimal. It is recommended to regularly check whether the antenna is clean and whether the housing is sealed.
- Check antenna scaling every 6 months
- Verify output current accuracy once a year
- It is recommended to install a surge protector in thunderstorm areas
