Abstract: the principle of ultrasonic flowmeter scale acoustic information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Divided into two major categories of electromagnetic and mechanical wave wave according to the nature. Electromagnetic wave is generated due to the effect of electromagnetic force and electromagnetic field changes in space communication process. Electromagnetic wave can be divided by frequency radio waves, infrared rays, visible light, ultraviolet, X-ray, etc. Machine. More flow meter manufacturers choose model price quote you are welcome to inquire, is a principle of ultrasonic flowmeter scale acoustic article details below. Divided into two major categories of electromagnetic and mechanical wave wave according to the nature. Electromagnetic wave is generated due to the effect of electromagnetic force and electromagnetic field changes in space communication process. Electromagnetic wave can be divided by frequency radio waves, infrared rays, visible light, ultraviolet, X-ray, etc. Mechanical wave is due to mechanical force produced by the mechanical wave propagation in the medium, its transmission is mechanical energy, can only be spread in the media. Sound is a mechanical wave, according to the divided into sound, but WenShengBo, ultrasonic frequency. Less than 20 hz frequency wave is sound; In the 20 ~ 20000 hz frequency wave become WenShengBo; In more than 20 KHZ frequency wave called ultrasonic. Ultrasound is a mechanical vibration wave in more than 20 KHZ frequency, its good directivity, energy concentration, penetrating power is big, can penetrate several meters thick steel plate, little energy consumption, to meet the interface of two kinds of medium, can produce obvious phenomenon of reflection and refraction. Ultrasonic wave in the process of communication there is a recession phenomenon, this is because the dielectric absorption of ultrasonic energy. Ultrasonic attenuation in air quickly, especially when high frequency attenuation faster, so in air when using low frequency ultrasound, generally in a few kHz, ( 40 khz) And slower attenuation in liquid and solid, spread far away, so can be used in high frequency, generally a few hundred kHz or higher. Ultrasonic sensor application scope is broad, can be used to measure flow ( Ultrasonic flowmeter) , liquid level measurement ( Ultrasonic level meter) , measuring level ( Ultrasonic level meter) Measuring the thickness of the material and anti-theft alarm. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
Whether it's automation or artificial intelligence, the rapid convergence of technology and business often determines mass flow meter’s competitiveness.
If you are looking for an excellent service in the UK then you can go to Beijing Sincerity Automatic Equipment Co., Ltd. They have almost everything what you might require for your u shape coriolis mass flow meter.
Depending on the scale of the service, Beijing Sincerity Automatic Equipment Co., Ltd might also need to hire and manage an overseas workforce and comply with regulatory requirements.
