Premium ultrasonic level switch 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 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.
Due to the non-contact measurement, the measured medium is almost unlimited. It can be widely used to measure the height of various liquid and solid materials. The ultrasonic liquid level transmitter is composed of three parts: ultrasonic transducer, processing unit and output unit. See even more information on non contact liquid 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.
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.
