Ultrasonic water level sensor online shopping by drurylandetheatre.com? The sensor of the High-Pro type liquid level controller couples the generated high-frequency ultrasonic pulse to the vessel wall through a couplant. The pulse propagates in the wall of the container and in the liquid. It will also be reflected by the inner surface of the container. By detecting and calculating the characteristics of the reflected signal. The measured data is transmitted to the on-site secondary meter through the 485 serial port in real time. It can be judged whether the liquid level reaches the position where the controller is installed.
The advantages of ultrasonic liquid level gauge are very outstanding. It is mainly reflected in the following aspects : Adopt non-contact measurement. It is not easily affected by the viscosity and density of the liquid. Of course, the ultrasonic liquid level gauge also has its own limitations and insurmountable defects. Specifically, it is mainly manifested in: Ultrasonic liquid level gauge should not be used to measure pressure vessels. Because the pressure mainly affects the probe. There is also a certain relationship between the pressure and the temperature. The change in pressure will affect the change in temperature. This will affect the change in the speed of sound. The accuracy of the measurement will be affected.
In the measurement, the ultrasonic pulse is emitted by the sensor (transducer), and the sound wave is reflected by the liquid surface and then received by the same sensor or ultrasonic receiver. Through piezoelectric crystal or magnetostrictive device into electrical signals. The distance between the sensor and the measured liquid surface is calculated by the time between the transmission and reception of sound waves.

HS-2000 External Mounted Ultrasonic Tank Level Sensor- (referred to as “external level gauge”). It adopts advanced signal processing technology and high-speed signal processing chip. It breaks through the influence of container wall thickness. Realizes the height of the liquid level in the closed container True non-contact measurement. The ultrasonic liquid level sensor (probe) is installed directly under the outer wall (bottom) of the container under test. Non-contact measurement function , Ultrasonic sensor probe is external. No need to open a hole in the container to be tested.
What does a level switch do? The function of the liquid level switch is to control the liquid level. For example, the water pump fills the pool with water, and the level switch can make the water in the water tank neither overflow nor empty, and there is always water. “ Can ultrasonic sensor detect water level? The ultrasonic sensor can of course measure the water level. When the ultrasonic level gauge is working, the high-frequency pulse sound wave is emitted by the transducer (probe), and is reflected on the surface of the measured object (water surface). The reflected echo is received by the same transducer (probe) and converted into an electrical signal . The time between pulse sending and receiving (the movement time of the sound wave) is proportional to the distance from the transducer to the surface of the object. Read extra details on here.
