The instrument cannot be installed in the arched or domed roof intermediate. In addition to produce indirect echo is also affected by the echoes. Multiple echo can be larger than the real value of signal echo, because through the top can concentrate multiple echo. So cannot be installed in a central location.
Radar Level Meter Maintenance
1. Confirm whether the grounding protection is in place. To prevent electrical leakage from causing damage to electrical components and interference with normal signal transmission, remember to ground either end of the radar meter and the signal interface of the control room cabinet.
2. Whether lightning protection measures are in place. Although the radar level gauge itself supports this function, external lightning protection measures must be taken.
3. The field junction box must be installed strictly in accordance with the installation instructions, and waterproof measures must be taken.
4. The field wiring terminals must be sealed and isolated to prevent liquid intrusion from causing short circuits in the power supply, wiring terminals and circuit board corrosion.
