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.
The quality of air directly affects people's lives and health. People can detect changes in air quality through their senses and take appropriate measures accordingly. Clean air helps to improve people's health and quality of life. Therefore, we should pay attention to the air quality proble...
Most of the modern meteorological monitoring stations are developing in the direction of all-day unattended operation. The establishment of automatic meteorological monitoring stations is in urgent need of more accurate and maintenance-free automatic monitoring instruments, including wind anemometer...
Winter wheat and summer corn have their own requirements for soil moisture conditions. For winter wheat, a soil relative water content of 70% - 75% is ideal for sowing, which facilitates seed-soil contact and germination. Too dry or too wet conditions can affect germination and seedling growth. Duri...
