High Frequency Radar Level Sensor Radar Distance Measurement
--------As gold supplier in 9 consecutive years
Water tank radar level sensor antenna microwave pulse is narrow, the downward transmission antenna. Microwave exposure to the medium surface is reflected back again by the antenna system receives, sends the signal to the electronic circuit automatically converted into level signals (because the microwave propagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost instantaneous).
This series of radar level sensor adopted 26G high frequency radar sensor, the maximum measurement range can reach up to 70 meters. Antenna is optimized further processing, the new fast microprocessors have higher speed and efficiency can be done signal analysis, the instrumentation can be used for reactor, solid silo and very complex measurement environment.
The CX-RLM-806 water tank radar level sensor,the medium is liquid ,could measure the Corrosive liquids.The frequency is 26G,so with higher accuracy.
The CX-RLM-808 water tank radar level sensor ,the medium is liquid(measure range :70m) andsolid .But measure range is less than 55m.The 808 Model with Multidirectional flange.

C.[Installation]
1. Installation Location
- The distance from tank to level meter must more than 1/6 diameter of tank;
- The min distance from the tank wall is 300mm;
- Can not installa the level meter on the top of feed inlet;
- Can not installa the radar level meter at central location;
- Within the signal beam,there should be no installation.
2.Guide wave installation
- Do not tilt the antenna to the pipe wall;
- To min temperature effects,pls installa the washer at the flange connection;
- The rod antenna must have a short pole at the launch of the radar;
- Vertical antenna rod, do not let the radar wave pointing to the tank wall.
3.Intelligent radar level meter installation
- Should installa the level meter at 1/4 or 1/6 diameter;
- Bell mouth alignment level surface is sloped pls adjust the angle of flange.
