Top level indicator for tank provider? Product features: Large display range, wide range of use, suitable for low temperature, medium temperature, high pressure occasions. It can be matched with remote transmitter output 4-20MADC standard signal to realize remote display of liquid level guage. It can also be matched with liquid level switch to realize liquid level control. Generally speaking, the material level feedback is inaccurate and untimely, which is very prone to explosion events, and there is a greater safety risk. Therefore, the requirements for the radar level meter are very high, but the radar level meter often has abnormal material level jumps or falls, or even crashes, resulting in large errors in material level measurement, which brings trouble to production and sales.

Secondly, in cement production, material level measurement encountered another difficulty is strong dust interference, especially pneumatic conveying powder silo, dust flying when feeding, low visibility, laser level meter and high energy ultrasonic level meter can not be measured, although radar level meter at this time can receive part of the surface echo. But the echo signal was also weakened. In addition, due to the uneven surface of the radar echo is refracted, will also lead to the existence of radar echo; In addition, there are some conditions from the bottom to the bin inflation, so that the material surface loose, material level measurement is more difficult.
Application conditions, application conditions generally include calm liquid level, slightly fluctuating surface, turbulent surface, with stirring, with foam and so on. The more complex the conditions, the more interference echoes, and the smaller the actual measured range. In a complex environment, a precision radar with strong ability to deal with interference echoes or an antenna with a larger size should be selected.
The radar level gauge works by electromagnetic waves. Its working principle is to measure the specific liquid level by transmitting electromagnetic waves to the measured target. After the electromagnetic waves are emitted, they are reflected by the medium. For the radar level gauge, its key function is to ensure that it can transmit magnetrol guided wave radar signals smoothly. In our industrial production site, interference often occurs, so which interference sources will affect the measurement of the radar level gauge? let’s see.
Working principle: Working principle of radar level gauge: UHF electromagnetic waves are transmitted to the liquid level of the container under test through the cable or antenna. When the electromagnetic wave touches the liquid level and is reflected back, the instrument detects the time difference between the initial wave and the echo, thereby calculating the liquid level height. Select guided wave radar or airborne radar according to the dielectric constant and measurement length of the measured medium.
So what are the installation technical requirements for radar water level meters? The installation of the radar water level meter must be vertical to the object to be measured; there should be no obstructions between the measured object and the radar water level meter, otherwise it will affect the reflection of radar waves, that is, affect the measurement accuracy; the center of the radar water level meter is far from the shore of the water body. The distance must be greater than the radius of the transmitting beam, otherwise the measurement accuracy will also be affected; the installation cantilever bracket of the radar water level meter must be firm, and cannot be shaken up and down; in order to protect the radar water level meter, the water level meter can be installed on the cantilever bracket. Iron box, put the radar water level meter probe.
