Abstract: The sound wave principle information of ultrasonic flow meter is provided to you by excellent flow meter and flow meter manufacturers. Waves are classified into two categories according to their properties: electromagnetic waves and mechanical waves. Electromagnetic waves are generated due to the action of electromagnetic force, and are the propagation process of electromagnetic field changes in space. Electromagnetic waves can be divided into radio waves, infrared, visible light, ultraviolet light, X-rays, etc. by frequency. machine. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the article on the principle of ultrasonic flowmeters. Waves are classified into two categories according to their properties: electromagnetic waves and mechanical waves. Electromagnetic waves are generated due to the action of electromagnetic force, and are the propagation process of electromagnetic field changes in space. Electromagnetic waves can be divided into radio waves, infrared, visible light, ultraviolet light, X-rays, etc. by frequency. Mechanical wave is the propagation of mechanical waves in the medium due to mechanical force. It propagates mechanical energy and can only propagate in the medium. Sound wave is a kind of mechanical wave, which is divided into infrasound wave, audible sound wave and ultrasonic wave according to the frequency. Waves with frequencies below 20Hz are infrasound waves; waves with frequencies between 20 and 20,000Hz are audible sound waves; waves with frequencies above 20kHz are called ultrasonic waves. Ultrasound is a mechanical vibration wave with a frequency above 20kHz. It has good directivity, concentrated energy, and large penetration ability. It can penetrate several meters of steel plates with little energy consumption. When encountering the interface between two media, it can Produces obvious reflection and refraction phenomenon. The ultrasonic wave has a certain decay phenomenon in the process of propagation, which is caused by the absorption of the energy of the ultrasonic wave by the medium. Ultrasound decays faster in the air, especially when the frequency is high, so ultrasonic waves with a lower frequency are used when propagating in the air, generally at tens of kHz (40kHz), while the attenuation is slower in liquids and solids. Propagation is farther, so higher frequencies can be used, typically a few hundred kHz or more. Ultrasonic sensors have a wide range of applications and can be used to measure flow (ultrasonic flowmeter), liquid level (ultrasonic level gauge), material level (ultrasonic level gauge), material thickness and anti-theft alarm. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'The principle of ultrasonic flow meter sound wave'
