At present, radar water level meter can be used in different working conditions such as river, channel, culvert and so on to measure water level change, although the water is not corrosive, compared to the oil industry, chemical industry and other complex industries, the working condition is relatively simple, but also need to pay attention to many problems, only to do the details, can ensure that the radar water level meter measurement accurate, effectively extend the service life, Save business costs. Today, we share some tips for installing and using radar water level meters to help you better use radar water level meters.
Measurement Principles & Advantages
Radar water level gauge Radar water level gauge is an electronic device that uses electromagnetic waves to detect targets. Its main function is used for water conservancy monitoring, sewage treatment and flood prevention early warning. Its main measurement principle is to emit radar pulses from the radar water level sensing antenna, the antenna receives the pulse reflected back from the water surface, and records the time T, because the propagation speed of electromagnetic wave C is a constant, thus obtaining the distance to the water surface D.
The technology of radar water level gauge is mature, with the advantages of measuring accuracy, stability, flexibility, high reliability, low power consumption, easy installation, convenient parameter setting, simple maintenance, and not limited by environment and geographical location.

"
1, before installation, be sure to do a good job of inspection, mainly check the sealing head and cable of the radar water level gauge, to ensure that the sealing head and cable are not damaged. 2, in the installation, the cable head must be tightened, before entering the electrical interface, the cable must be bent downward to ensure that the shell does not flow into the water, unused electrical interface must be plugged tightly. 3, installation, need to install a rain cover, summer rainy and direct sunlight, in order to extend the service life of the radar water level meter, it is recommended to install a rain cover to reduce the impact of direct sunlight and rain on the radar water level meter. 4, ensure that the cable meets the electrical connection specifications, cable connection details related to the normal use of radar water level gauge and social life and property safety, must be strictly in accordance with the relevant requirements. 5, pay attention to the horizontal rod when installing, it is recommended to make the horizontal rod can be rotated or telescopic horizontal rod, convenient for later adjustment and maintenance. 6, it is worth mentioning that when measuring the channel, the radar water level meter should be installed in the middle of the channel. The channel is generally narrow and installed in the middle, which can minimize the impact of the channel wall on the radar water level gauge. 7, finally, pay attention to observe the radar water level gauge, do a good job of daily maintenance, problems should be timely feedback.
