Top ultrasonic tank level sensor online shopping? Liquid level controller refers to the control of high and low liquid levels through mechanical or electronic methods. It Can control solenoid valves, water pumps, etc. So as to achieve semi-automation or full automation. There are many methods, depending on the choice of different products. The float type liquid level controller is composed of a magnetic float, a measuring tube, a signal unit, an electronic unit, a junction box and installation parts. Generally, the specific gravity of the magnetic float is less than 0.5, which can float on the liquid surface and move up and down along the measuring tube. A measuring element is installed in the catheter. It can convert the measured liquid level signal into a resistance signal proportional to the change of liquid level under the action of external magnetism. And convert the electronic unit into 4-20ma or other standard signal output.
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.
