Ultrasonic tank level measurement online shopping from drurylandetheatre.com? 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 : Safe and clean. The instrument has long service life. The measurement is stable and reliable with high precision. 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.

The External Ultrasonic Tank Level Sensor adopts the sonar echo ranging principle. It overcomes the influence of the tank wall on the transmission of ultrasonic signals. It adopts advanced digital signal processing technology. It can truly realize non-contact, high-precision measurement of the liquid level in the tank. The External Ultrasonic Tank Level Sensor can output 4-20mA standard signals or output the measurement results to the upper computer (or secondary meter) through the RS-485 interface. It can meet the automatic control of the system.
Ultrasonic Level Switch is not affected by factors such as medium density, dielectric constant, conductivity, reflection coefficient, pressure, temperature, precipitation, etc. It is suitable for various liquid levels in the pharmaceutical, petroleum, chemical, electric power, food and other industries Engineering control. Ultrasonic Level Switch is the ideal choice for the detection of toxic, highly corrosive, and dangerous liquid level. Sino-Inst offers a variety of Radar Level Transmitters for level measurement.
