FMR62B Installation and Commissioning Points
Correct installation is the prerequisite for ensuring the measurement accuracy of the FMR62B. The following steps apply to most liquid and solid level scenarios.
- Select Installation Location: Avoid the feed inlet, agitator, and tank wall, and ensure there are no fixed obstacles within the antenna beam range.
- Reserve Installation Nozzle: The nozzle length should be as short as possible, and the inner wall should be smooth to avoid false echoes.
- Grounding and Shielding: The instrument housing must be reliably grounded, and the signal cable should use shielded twisted pair.
- Parameter Setting: Input the empty tank height, full scale, and medium dielectric constant via HART communicator or commissioning software.
- Echo Curve Verification: Observe the echo curve to confirm that the real level echo is higher than the false echo.
FMR62B Selection Comparison and Precautions
Under different working conditions, the selection focus of the FMR62B varies. The following table compares recommended configurations for common application scenarios.
| Application Scenario | Recommended Antenna Type | Key Consideration |
|---|---|---|
| Liquid Storage Tank | Horn or rod antenna | Choose rod type when dielectric constant is low |
| Solid Silo | Horn antenna | Pay attention to dust and angle of repose |
| Corrosive Media | PTFE fully sealed antenna | Wetted materials must be compatible |
| High Temperature and High Pressure | Antenna with extension tube | Check temperature and pressure ratings |
Note: The FMR62B is not suitable for media with a dielectric constant lower than 1.5, and the measurement range is affected by the medium's reflection characteristics. Before selection, be sure to confirm the process connection, supply voltage, and explosion-proof rating.
Frequently Asked Questions (FAQ)
Does the FMR62B require regular calibration?
Usually no regular calibration is required, but it is recommended to check the echo curve and output current once a year. If the medium characteristics change significantly, empty tank and full tank calibration should be performed again.
Can the FMR62B be used in stirred tanks?
Yes, but a stilling well or guide tube should be installed, and the installation position should be adjusted to avoid vortices. It is also recommended to enable the stirring suppression function.
