Installation and Commissioning Points
Installation Precautions
- The installation position should avoid the feed inlet and agitator to prevent false echoes.
- The probe should be as perpendicular to the medium surface as possible to ensure a stable echo signal.
- For solid material measurement, it is recommended to use cable or rod probes, and pay attention to the load-bearing capacity of the mounting flange.
- In steam or condensing environments, the influence of probe condensation must be considered, and a model with steam compensation should be selected if necessary.
Commissioning Steps
- Power on and confirm that the instrument self-test is normal.
- Connect the instrument via the display module or commissioning software (such as PACTware).
- Set basic parameters: medium type, probe length, measuring range, output signal.
- Perform empty tank and full tank calibration, or input a known distance for linearization.
- Check the echo curve to ensure good signal quality, and adjust the threshold if necessary.
- Save parameters and exit commissioning mode.
Common Problems and Maintenance
- Fluctuating measurement values: Check whether the probe has material buildup, scaling, or agitation interference.
- No echo signal: Confirm whether the dielectric constant of the medium is too low, or whether the probe is damaged.
- Abnormal output current: Check whether the supply voltage and loop load are within the allowable range.
- Regular maintenance: It is recommended to check the probe cleanliness and sealing status every six months.
