Ultrasonic level gauge products have automatic power adjustment, gain control, and temperature compensation. The measurement line of the ultrasonic level gauge is more complicated than the general level gauge. This is because, in general industrial metering, the flow rate of liquid is often several meters per second, so it is necessary to have a perfect measurement circuit to achieve. This is precisely the ultrasonic level gauge can only be practically applied under the premise of rapid development of integrated circuit technology. s reason. According to the principle of signal detection, the current ultrasonic level gauge can roughly divide the propagation speed difference method. The principle and structure of the noise method are the simplest, which is convenient for measurement and carrying. The price is cheap but the accuracy is low, which is suitable for flow measurement accuracy. Use in places where the requirements are not high. In principle, the measurement accuracy is independent of the speed of sound in the fluid, and thus has nothing to do with the temperature, concentration, etc. of the fluid, so the measurement accuracy is high and the scope of application is wide.

Ultrasonic liquid level meter products have automatic power adjustment, gain control, temperature compensation, advanced detection technology and calculation technology, improve the measurement accuracy of the instrument, and suppress the interference echo to ensure the true measurement results. The product can be widely used for the measurement of liquid level and solid level of various liquids, and also for distance measurement. A digital level meter controlled by a microprocessor. In the measurement, the pulsed ultrasonic wave is emitted by the sensor (transducer), and the sound wave is reflected by the surface of the object and then received by the same sensor and converted into an electrical signal. The distance from the sensor to the measured object is calculated from the time between the transmission and reception of the sound wave. Due to the non-contact measurement, the measured medium is almost unlimited and can be widely used for the measurement of various liquid and solid materials.
