Radar Level Gauge Installation

Precautions


1: The measurement range is calculated from the point where the beam touches the tank low, but in special cases, if the tank bottom is concave or tapered, the measurement cannot be performed when the level is below this point.


2: If the medium is of low dielectric constant when it is at a low liquid level.


3: In theory, it is possible to measure the position of the antenna tip, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100 mm away from the antenna tip.


4: For the overflow protection, a safety distance can be defined and added to the blind zone.


5: The minimum measurement range is related to the antenna.


The measurement range is calculated from the point where the beam hits the tank low, but in special cases, if the tank bottom is concave or tapered, the measurement cannot be performed when the level is below this point.


If the medium has a low dielectric constant when it is at a low liquid level, the bottom of the tank is visible. At this time, in order to ensure the measurement accuracy, it is recommended to set the zero point at a low height of C.


For the overflow protection, a safety distance can be defined and added to the blind zone.


The minimum measurement range is related to the antenna.


Radar level gauge installation requirements:


1. Try not to install radar level transducer in the center of the jar.


2. The distance from the tank wall is 1/6 of the tank diameter, and the minimum distance is 200mm.


3. Cannot be installed above the inlet.


Note: 

The measurement range is calculated from the point where the beam touches the tank low, but under special circumstances, if the tank low is concave or conical, the measurement cannot be performed when the level is below this point. If the medium has a low dielectric constant and the tank is visible when it is at a low liquid level, to ensure measurement accuracy, it is recommended to set the zero point at a low height of C. 


Theoretically, it is possible to measure the position of the antenna tip, but considering the effects of corrosion and adhesion, the final value of the measurement range should be at least 100 mm away from the antenna tip. For the overflow protection, a safety distance can be defined and added to the blind zone. The minimum measurement range is related to the antenna.
