At present, radar water level meters can be applied in different working conditions such as rivers, nullahs, culverts, etc. used to measure water level changes, although the water is not corrosive, relatively simple working conditions than the chemical industry, food processing industry, and other complex industries.
But also still also need to pay attention to many issues, only the details do a good job, can extend the service life of the instrument, improve the accuracy of the radar water level meter measurement, and achieve good measurement results at the same time, but also for the enterprise to save costs, today to share a few tips on the installation and use of radar water level meter.
A radar water level meter, also known as water level radar, is an electronic device that uses electromagnetic waves to detect targets. Its main function is to carry out water monitoring, sewage treatment, and flood prevention and warning. The main measurement principle is to transmit radar pulses from the radar water level induction antenna, which receives the pulses reflected from the water surface and records the time T. Since the propagation speed C of electromagnetic waves is constant, the distance D is obtained from the water surface. It has no mechanical wear and tear, uses non-contact type measurement, measurement is independent of water quality, is not affected by floating objects such as ice floes no need for anti-wake wells, has no effect on water flow, has long service life, and has easy maintenance.
There are some special tips that we need to pay attention to when using the installation. Before installation, must do a good job of inspection, mainly check the radar water level meter sealing head and cable, to ensure that the sealing head and cable are not damaged. During installation, the cable head must be tightened, and before entering the electrical interface, the cable must be bent downward to ensure that the housing does not flow into the water, and the unused electrical interface must be plugged in tightly.
Also during installation, a rain cover needs to be installed. In the summer it is rainy and in direct sunlight, in order to prolong the life of the radar water level meter, it is recommended to install a rain cover to mitigate the effects of direct sunlight and rain on the radar water level meter. In addition, to ensure that the cable meets the electrical connection specifications, cable connection details are related to the normal use of the radar water level meter and the safety of life and property of the community must be strictly in accordance with the relevant requirements.
The installation should pay attention to the horizontal bar, it is recommended that the horizontal bar is made into a rotatable or retractable horizontal bar, which is convenient for later adjustment and maintenance. It should be mentioned 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, and can minimize the influence of the channel wall on the radar water level meter.
Finally, we should pay attention to the observation of the radar water level meter, and do a good job of daily maintenance, problems should be timely feedback.
