FMR63B Core Working Principle
FMR63B adopts Frequency Modulated Continuous Wave (FMCW) radar technology, transmitting high-frequency microwaves and receiving echoes, calculating the frequency difference to determine the distance to the material surface. This principle is unaffected by changes in medium density, temperature, or pressure, making it suitable for complex working conditions.
Main Technical Features
- Non-contact measurement: No wear, maintenance-free, suitable for corrosive media.
- High precision: Typical accuracy up to ±2mm, meeting trade settlement-level requirements.
- Wide range: Maximum measuring range up to 30 meters, covering most storage tanks and silos.
- Strong anti-interference: Built-in echo processing algorithms to suppress agitation, foam, and condensation effects.
FMR63B Technical Parameters and Selection
During selection, focus on process connection, antenna type, power supply, and output signal. The table below lists typical FMR63B parameters for procurement and design reference.
| Parameter | Specification |
|---|---|
| Measuring principle | FMCW radar |
| Measuring range | 0.3m ~ 30m (depending on antenna) |
| Accuracy | ±2mm |
| Process temperature | -40°C ~ +200°C |
| Process pressure | -1bar ~ +40bar |
| Output signal | 4-20mA/HART, PROFIBUS PA, Modbus |
| Protection class | IP66/IP67 |
| Antenna type | Horn, rod, cable |
Selection Steps
- Confirm medium characteristics (dielectric constant, corrosiveness, condensation).
- Select antenna type and size based on range and installation location.
- Verify process connection standard (flange/thread) and sealing material.
- Determine supply voltage and output protocol to match the control system.
Installation and Commissioning Points
Correct installation position can significantly improve FMR63B measurement stability. It is recommended to avoid the feed inlet, agitator blades, and tank wall, and ensure the antenna is perpendicular to the material surface.
Installation Precautions
- The installation nozzle length should be as short as possible to avoid false echoes.
- For solid level, it is recommended to use cable or rod antennas with a universal flange.
- In condensation-prone conditions, instruments with purge or heating options can be selected.
Commissioning Process
- After power-on, connect to the instrument via HART communicator or commissioning software.
- Enter basic parameters such as empty tank height, full range, and medium dielectric constant.
- Perform false echo suppression to record fixed interference echoes in the tank.
- Observe the echo curve to confirm signal strength and signal-to-noise ratio meet requirements.
- Save parameters and record the commissioning report for future maintenance.
Common Faults and Maintenance
FMR63B is generally maintenance-free, but after long-term operation, measurement abnormalities may occur due to antenna scaling or parameter drift. The table below lists typical faults and handling suggestions.
| Fault Symptom | Possible Cause | Handling Measure |
|---|---|---|
| Measured value jumps | Agitation or foam interference | Enable echo suppression, adjust installation position |
| No echo signal | Antenna scaling or damage | Clean antenna, check cable connection |
| Output current constant | Parameter error or module failure | Restore factory settings, replace electronic module |
| Accuracy decreased | Dielectric constant change | Re-enter medium parameters and calibrate |
Regularly check antenna cleanliness and sealing condition to extend FMR63B service life and ensure measurement reliability.
