introductionAt present, one of the difficult problems faced in the extraction of crude oil in oil fields is the online measurement of the extracted crude oil. The main reason is that the composition of crude oil is very complex. The crude oil contains oil, water, gas and other impurities. It is a mu

Principle classification of measuring water flow The principle of measuring the water flow by the time difference method,at a certain distance upstream and downstream of the measuring pipeline, two pairs of ultrasonic transmitting and receiving probes (F1, T1) and (F2, T2) are installed respectively

Because of the improvement of ultrasonic transducer technology, they are cheaper, more accurate, smaller in size, and can be bought everywhere, so ultrasonic technology has been widely used in flow measurement. The advanced integrated analog circuit makes it easier to capture and process the ultraso

The ultrasonic flowmeter transducer sensor we use is mainly designed according to the principle. When it is used in industry, it not only has the characteristics of measurement management, but also has the characteristics of process monitoring. It is widely used in petroleum, chemical, pharmaceutica

In the industrial production, various sealed liquids are often used to store high-temperature, toxic, volatile, flammable, explosive, and highly corrosive liquid media. For ultrasonic depth transducer of these containers, non-contact measurement must be used.When the ultrasonic level gauge is used f

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

The propagation path of the ultrasonic waves is called a channel. The additive noise of the channel is mainly determined by the undulating noise, ultrasonic transducers sensor in turn can be regarded as Gaussian white noise. Since additive noise is considered to only affect the reception of the sign

The resonant frequency and bandwidth of ultrasonic transducers are selected from the PZT-5A piezoelectric ceramic disc polarized in the thickness direction as the transducer, and the radius R of the piezoelectric ceramic disc is 6mm and has a thickness h. The height of the outer surface of the inner

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
