How to choose the correct type of sewage flow meter

Abstract: The information on how to correctly select the sewage flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. The flow measurement is very complicated. In order to achieve the purpose of accurate measurement, it is necessary not only to understand the principle and characteristics of the flowmeter, but also to pay attention to the relevant matters of the entire measurement system. As far as the use is concerned, it is necessary to select, install, use, maintain, etc. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the article details on how to correctly select the sewage flowmeter. The measurement of flow is very complicated. In order to achieve the purpose of accurate measurement, it is necessary not only to understand the principle and characteristics of the flowmeter, but also to pay attention to the relevant matters of the entire measurement system. As far as the use is concerned, it is necessary to pay attention to the selection, installation, use, maintenance and other links to ensure the correct and reasonable use of the measuring instrument. Matters needing attention in the selection (1) The choice of the electromagnetic flowmeter lining will be directly related to the correct use and life of the electromagnetic flowmeter. Therefore, it is necessary to choose different linings according to the temperature, pressure, speed of the measured fluid, as well as the hardness, content and particle size of the solid particles. (2) The range of the electromagnetic flowmeter should be suitable for the actual needs of the process parameters. The process range is 80%-90% of the range of the selected electromagnetic flowmeter; the lower limit of the measurement should consider the signal-to-noise ratio of the electromagnetic flowmeter detector; the suitable fluid pressure range is: -0.098MPa ~ 2.941MPa, because the pressure of the fluid Too high will affect the service life of its electrodes. Too low may cause the lining to fall off. (3) If the fluid contains iron sand and other magnets, it will disturb the magnetic field of the instrument and cause corresponding errors; if the fluid contains air bubbles. The measured flow is the volume flow including air bubbles; for example, when the fluid has sedimentation or scarring. It will cause its electrodes to be covered by foreign objects and cause the zero point fluctuation of the instrument. At present, some electromagnetic flowmeters use the method of adding ultrasonic waves to their measuring electrodes to eliminate the precipitation and scarring of the fluid on the electrodes. (4) Particles in the fluid may strike the electrode to form spike noise. Affects the stability of the flow meter indication. In this case, an electromagnetic flowmeter with electrodes covered with porous ceramic or conductive rubber can be used. The measurement of flow is very complicated.
