Ultrasonic level switch online store by Drurylandetheatre? 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 measurement is easily affected by temperature. In the actual measurement, the change of temperature will cause the change of sound speed. This will lead to errors in the measurement.
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. Discover additional information at ultrasonic tank level sensor.
Calibrate the outer wall of the probe. There is no need to open holes for the container to be tested, easy to install, and does not affect production. It can accurately measure the level of various toxic substances, strong acids, strong alkalis and various pure liquids in high-pressure airtight containers. The HS-2000 External Mounted Ultrasonic Tank Level Sensor has no special requirements for the material of the liquid medium and the container. The explosion-proof design is adopted to meet the explosion-proof requirements. Auto-calibration function : With self-calibration function. It overcomes the problem of reduced accuracy after long-term use of traditional liquid level gauges.
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.
