1.Principle of level sensor for water product
level sensor for water is a device that measures the level of water in a fixed container that is too high or too low, and is used to detect the level of water in a tank, pond, river, or any other body of water.The radar level antenna emits narrow microwave pulses, which are transmitted downward through the antenna. After the microwave contacts the surface of the measured medium, it is reflected back and is received again by the antenna system. The signal is transmitted to the electronic circuit part and automatically converted into a level signal (because the microwave propagates extremely fast, the electromagnetic wave reaches the target and is reflected back to the receiver. The time taken is almost instantaneous).

3. Product features of level sensor for water
The antenna is small in size and easy to install; the non-contact radar has no wear and pollution.
Almost unaffected by corrosion and foam; almost unaffected by water vapor, temperature and pressure changes in the atmosphere.
Serious dust environment has little impact on the work of high-frequency level meters.
The wavelength is shorter and reflects better on tilted solid surfaces.
The beam angle is small and the energy is concentrated, which enhances the echo capability and helps avoid interference.
The measurement blind area is smaller, and good results can be achieved for small tank measurements.
High signal-to-noise ratio for better performance even under fluctuating conditions.
High frequency, it is the best choice for measuring solids and low dielectric constant media.
In the daily operation of wastewater treatment plants, ammonia nitrogen detection is essential. Ammonia nitrogen refers to the nitrogen present in water in the form of free ammonia (NH3) and ammonium ions (NH4+). Excessively high ammonia nitrogen levels can deplete dissolved oxygen in water bodies,...
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...
Agriculture sensors are used in agricultural production to collect data required for the growth of farmland crops, such as air temperature and humidity, light intensity, and carbon dioxide, and to monitor changes in factors such as farmland, weather, irrigation, and fertilization....
