The core of the underwater acoustic transducer is a piezoelectric wafer in its outer casing, and there are many kinds of materials constituting the wafer. The size of the wafer, such as diameter and thickness, varies, so the performance of each probe is different and its performance must be known be

Ultrasonic flowmeters are widely used in various production facilities in our factory. The mediums test include water, hydrocarbons and lye. The ultrasonic flowmeters used in our factory are available in various domestic and foreign models and specifications. Compared with traditional mechanical fl

There are many characteristics of the gas flow sensor. What are the specific characteristics? The gas flow sensor has no moving parts due to the vortex flow sensor,which has small pressure loss, high precision piezo ceramic disc and is easy to maintain. The flow rate of the air measured on a pipe wi

The water flow sensor measures the magnetic physical by using the hall effect of the hall element. A load resistor is connected to the positive pole of the hall element while a value of 5V is applied.The water flow transducer for flowmeter measures the magnetic physical quantity by using the Hall ef

Ray characteristics of ultrasonic waves are formed in a straight line when they encounter two substances with different acoustic impedance ratios.At the interface, reflection and refraction transmission occurs. The reflection and refraction of ultrasonic waves follow the laws of geometric optics. Th
