Horn Antenna Radar Tank Level Sensor is a common non-contact tank level meter. Suitable for high temperature sealed storage tank. Support customized high temperature 500-1000℃.
Horn Antenna Radar Tank Level Sensor has good focusing characteristics and can be applied to most tanks. If the corresponding cooling measures are adopted, the temperature of the measured medium can reach 500-1000℃. The maximum measuring distance is 35 meters. It can be used for level measurement of storage tanks, intermediate buffer tanks or process vessels. But it is not suitable for measurement of corrosive media. Output 4~20mA superimposed HART signal.

Radar Tank Level Sensor Installation Notes
(1) The horn of the horn-type intelligent radar level gauge must exceed the inner surface of the mounting hole by a certain interval (at least greater than 10mm).
(2) The axis of the antenna of the intelligent radar level gauge should be perpendicular to the reflective surface of the liquid level.
In addition, when performing routine maintenance on the intelligent radar level gauge, users can remotely observe the reflected wave curve with a PC (equipped with MAT software). For interference waves that may be newly generated later, the level gauge can be used to identify false waves. Remove the influence of these interference reflection waves to ensure correct measurement.
(3) Objects such as the stirring valve in the tank, the adhesion of the tank wall and the path. If it is within the signal range of the intelligent radar level gauge, it will produce interfering reflected waves and affect the level measurement. When installing, choose a suitable installation location to avoid interference from these factors.
Radar Tank Level Sensor Installation Guide:
Be installed in the diameter of the 1/4 or 1/6.
Note: The minimum distance from the tank wall should be 200mm.
Note: ① datum
②The container center or axis of symmetry
The top conical tank level, can be installed at the top of the tank is intermediate, can guarantee the measurement to the conical bottom.
A feed antenna to the vertical alignment surface.
If the surface is rough, stack angle must be used to adjust the angle of universal flange of the antenna to the alignment surface.
(Due to the solid surface tilt will cause the echo attenuation, even Loss of signal.)
Radar Level Sensor Working Principle
Radar level transmitter 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.

B Low adjustment
D Blind area
Datum measurement: Screw thread bottom or the sealing surface of the flange.
Note: Make sure the radar level meter the highest level cannot enter the measuring blind area (Figure D shown below).

What is the difference between radar and ultrasonic level transmitter?
In actual application, there are two methods for radar level sensors, namely, frequency modulated continuous wave type and pulse wave type. The liquid level sensor using FM continuous wave technology has high power consumption, must adopt a four-wire system, and the electronic circuit is complicated. The liquid level sensor using radar pulse wave technology has low power consumption and can be powered by two-wire 24VDC, which is easy to achieve intrinsic safety and has a wider application range.
Ultrasonic sensors use sound waves, and radar uses electromagnetic waves. This is the biggest difference.
Moreover, the penetrating ability and directivity of ultrasonic waves are much stronger than electromagnetic waves, which is why ultrasonic detection is more popular now.
The difference between the main applications:
1. Ultrasonic accuracy is not as good as radar.
2. The relative price of radar is relatively high.
3. When using radar, consider the dielectric constant of the medium.
4. Ultrasound cannot be applied to working conditions such as vacuum, high steam content or foam on the liquid surface.
5. The radar measurement range is much larger than that of ultrasonic.
6. The radar has a horn type, a rod type, and a cable type. Compared with ultrasonic, it can be applied to more complicated conditions.
What are the different types of level sensors?
Types of Level Transmitters:
Level measurement transmitters are of seven types. Each type of transmitter works in a different way, and makes it useful for different types of processes.
Capacitance Level Transmitters
Hydrostatic Level Transmitters
Magnetic Level Transmitters
Radar Fill Level Transmitters
MUltrasonic Level Transmitter
Guided Microwave Level Transmitters
