The working principle of high frequency radar level meter:
FM continuous wave radar level meter general principle is the radar to the top of the tank radiation electromagnetic waves, electromagnetic waves encountered in the medium when the reflection by the radar to receive, send and receive signals between the frequency difference δ f and the media surface distance R is a certain proportion: R = c (speed) × δ f (frequency difference) × 2 (FM slope) × K. As the speed of light C and the FM slope K are known, so the estimated frequency difference δ f can be found radar The distance R from the material surface of the installation place, then the total height of the tank is known and the space distance between the radar and the material surface is deducted, i.e., the height of the material level can be obtained.

environmental parameters of sensors are used to monitor the atmospheric environment, which can detect temperature, humidity, pressure, light, rainfall, wind speed, wind direction, noise, PM2.5 and other environmental parameters....
weather instruments and their uses are used to collect weather data and monitor meteorological parameters such as temperature, atmospheric pressure, humidity, wind speed, wind direction, and rainfall....
Piezoelectric rain sensors use the impact measurement principle to measure the weight of individual raindrops and thus calculate the amount of rainfall. The raindrops are influenced by the weight of the raindrops and air resistance during their fall. When they reach the ground, the velocity is const...
