Wireless liquid level sensor and wireless monitoring of water level

The main purpose of the liquid level sensor is to monitor the water level and liquid level. It is often used in places such as petrochemical industry, waterworks, paper making, reservoirs and so on. With the wide application of liquid level sensors, an upgraded version of wireless liquid level sensors has appeared in front of the world, which is more accurate and stable. Including: radar level sensor, ultrasonic level sensor. The radar liquid
level sensor in the wireless liquid level sensor is a frequently used measurement technology, and has a variety of measurement values ​​displayed. Radar wireless liquid level sensors can be used well under many harsh conditions and play an important role.
The radar radio waves are used for measurement. The radar emits radio waves to collect the page height in the container, and the radio coupling signal returns to the radar receiving antenna. The frequency of the high-frequency radio signal sent by the radar wireless hydraulic sensor is as high as 26GHz, and the propagation speed in vacuum and air directly hits the speed of light. The time difference between the radio wave transmission and the reception after returning is proportional to the level of the liquid in the container. Up to now, the antennas used in radar wireless liquid level sensors are horn-shaped or whip-shaped.
Ultrasonic wireless liquid level sensors use the transmission and reception of ultrasonic waves to calculate the propagation distance based on the propagation time of ultrasonic waves. It has two kinds of ranging methods: one is the direct wave method that is transmitted at the two ends of the measured distance and the other end is received; the other is the transmitted wave method that is received after the transmitted wave is reflected by the object, which is suitable for ranging instrument.
