XDX-CR plug-in ultrasonic flowmeter Introduction: The plug-in ultrasonic flowmeter adopts the ultrasonic time difference principle to measure the flow, which can realize the flow measurement of DN15~DN6000 pipes. The pipe can be installed after opening, without pipe cutting, with a small amount of installation work. It can be installed under pressure without stopping the flow. It is not affected by the pipe wall and directly contacts with the media. On the basis of flow measurement, the ultrasonic heat metering function can also be selected to provide reference for the heating efficiency of the heating industry. When the ultrasonic beam propagates in the liquid, the flow of the liquid will cause a slight change in the propagation time, which is proportional to the flow velocity of the liquid. When the flow is zero, the time required for the two sensors to transmit and receive sound waves is the same. When the medium flows, the transmission time of the sound waves in the countercurrent direction is greater than that in the downstream direction. It adopts advanced multi pulse technology, digital signal processing technology and error correction technology, so that the flow meter can adapt to the environment of industrial site more easily, economically and accurately. The products have reached the advanced level at home and abroad. It has the characteristics of good stability, small zero drift, high measurement accuracy, wide range ratio and strong anti-interference. It can be used not only to measure the medium flow of large pipe diameter, but also to measure the medium that is not easy to contact and observe. In particular, the utility model can solve the flow measurement problem of the medium that cannot be measured by other instruments with open pipes. It is widely used in heating, municipal water supply, mobile multi-point measurement and other scenes and fields. characteristic: 1.
