Best non contact liquid 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 : 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 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 measures liquid levels based on the principle of ultrasound. When ultrasonic waves encounter a high-density medium while propagating in a low-density medium, they cannot penetrate the high-density medium. There will be reflections at the interface of the two media. The ultrasonic liquid level gauge is made using this feature. See extra information on non contact liquid level sensor.
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.
HS-ULC Ultrasonic Level Switch is specially used to measure the liquid level of tanks. Because it is installed on the outside of the tank, there is no need to punch holes, which is widely welcomed by customers. Of course, if your tank already has holes, you can also choose other tank level transmitters. The ultrasonic principle can also be used to measure water depth. Please refer to Portable Ultrasonic Water Depth Gauge for water depth measurement. The sensor of the external liquid level switch couples the generated high-frequency ultrasonic pulse to the container wall through the couplant.
