High quality ultrasonic fuel 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 : The structure is simple. The reading is convenient. It is very easy to install and maintain. 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 can not be used in the occasions with water mist, medium that is easy to produce a lot of foam, and volatile medium. Because this kind of working condition is easy to absorb the sound wave or interfere with the sound wave emission, the signal is lost and the accuracy is reduced.
Ultrasonic Level Sensing is a low-cost liquid level measurement technology. Ultrasonic Level Sensing sensors and transmitters are used for tank or river level measurement. Ultrasonic Level Sensing does not need to contact the medium, can be continuously measured, low cost. Therefore, Ultrasonic Level Sensing is very popular among users. Ultrasonic liquid level sensors are available in general and intrinsically safe types. Output 4~20mA standard signal or output the measurement result to the secondary meter through RS-485. Meets the system’s automatic control. Find even more information on https://www.drurylandetheatre.com/hs-ulc-ultrasonic-level-switch-external-mounted/.
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 installed outside the tank. No need to open holes in the tank. Non-Contact Measure. The ideal choice for tank level monitoring. Ultrasonic Level Switch, External Mounted (referred to as “external level switch”) is a new type of level measurement alarm device. Ultrasonic Level Switch is mainly used to detect the liquid level of the storage tank. It can realize the upper and lower limit alarm or monitor whether there is liquid in the pipeline (dry protection). The material of the storage tank can be various metals, non-metals or non-foamed plastics. The wall thickness can be Up to 70mm. See more information at https://www.drurylandetheatre.com/.
