Premium ultrasonic tank level sensor online store
Top external level switch online store? The Displacer level controller changes the magnetic float to a float. Displacer level transmitter uses tiny metal film strain sensing technology to measure liquid level, interface or density. Such as Fisher DLC3010 Digital Level Controller. The hydrostatic level controller works by using the measuring principle of hydrostatic pressure. Generally, a silicon pressure sensor is used to convert the measured pressure into an electrical signal. Then it is amplified by the amplifier circuit and compensated by the compensation circuit. Finally, it is output in 4-20ma or 0-10ma current mode. Sino-Inst offers over 10 Ultrasonic Liquid Level Controllers for level measurement. About 50% of these are fuel level meters, 40% is the tank level sensor.
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.

For spherical tanks equipped with a calibrator. The calibration sensor is installed at the center of the calibrator on the outer wall of the tank. If the calibrator is not installed, the calibration sensor should be installed at the height of the outer radius of the tank (equatorial zone). The calibration sensors for the vertical tank and the process tank are installed on the outer side of the tank body, at a height of 0.5m to 1m from the tank bottom. Note: After installing the calibration tube (calibrator) in the tank, the correct installation position should be marked with paint on the outside of the tank wall in time.
What is ultrasonic level sensor? Ultrasonic level sensor is a monitoring instrument for measuring liquid height, tank height, and material position. The ultrasonic level sensor can adopt two-wire, three-wire or four-wire technology. The two-wire system is: power supply and signal output are shared. The three-wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24v power supply, a 3-core cable can be used, and the negative terminal of the power supply and the negative terminal of the signal output share a core wire. The four-wire system is: when using AC 220v power supply, or when using DC 24v power supply. When the power supply loop and the signal output loop are required to be completely isolated. A 4-core cable should be used. Find even more info at https://www.drurylandetheatre.com/.
