What should I do if the clamp-on ultrasonic flow meter cannot display the flow rate?

Abstract: The information on what to do if the external clip-on ultrasonic flow meter cannot display the flow is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. The clip-on ultrasonic flowmeter can only measure liquids, such as tap water, sewage, seawater, pure water, reclaimed water and other relatively clean liquids. If the liquid contains a large amount of agglomerated dirt or a large number of bubbles, it will affect the transmission and reception of ultrasonic waves. The external clip type should not be used. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of how to do if the outer clamp ultrasonic flowmeter cannot display the flow. The clip-on ultrasonic flowmeter can only measure liquids, such as tap water, sewage, seawater, pure water, reclaimed water and other relatively clean liquids. If the liquid contains a large amount of agglomerated dirt or a large number of bubbles, it will affect the transmission and reception of ultrasonic waves. It is not advisable to use an external clamp-type intelligent ultrasonic flowmeter. Most oils and gases are also not suitable. The main steps in the installation of the clamp-on ultrasonic flowmeter are: selecting the installation point, inputting parameters, obtaining the installation distance of the sensor, applying couplant, and binding the sensor. Most users can understand how to do the above steps after reading the manual, but they still cannot display the flow rate after following the method. The main reasons are: 1. The installation distance automatically calculated by the flowmeter is too mechanical, and the distance is accurate. To install in mm, in fact, this distance is only a reference distance. Due to the influence of the pipeline environment, such as the deviation of the wall thickness and the unevenness of the inner wall, it may cause the deviation of the acoustic signal. Therefore, a very practical method for our actual installation is to fix the upstream sensor first, and then press the M90 ​​key on the host to check the signal strength and quality. Generally speaking, both UP and DN should be above 80, and the Q value below 50 cannot be measured normally by the flowmeter. 2. In user installation problems, UP and DN are often 0 when users check the M90 ​​menu. The main reasons for this situation are that no couplant is applied or the clamps are not tightened, and another reason is that there is no couplant in the pipeline during installation. water. 3. The reason why the Q value is 0 is mostly due to improper distance. At this time, open the M90 ​​menu, move the downstream sensor slowly, and fix it when the Q value gets a maximum value. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
