Installation requirements for pipeline electromagnetic flowmeters

Abstract: The information on the installation requirements of pipeline electromagnetic flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. 1. Requirements for straight pipe sections In order to improve the influence of eddy current and flow field distortion, there are certain requirements for the length of the flowmeter installed in the front and rear straight pipe sections, otherwise it will affect the measurement accuracy (a speed flow device can also be installed, try to avoid the nearest After the regulating valve and half-open valve are installed. For more flowmeter manufacturers to select models and prices, you are welcome to inquire. The following is the details of the installation requirements for pipeline electromagnetic flowmeters. 1. The requirements for straight pipe sections are to improve the eddy current and flow field Due to the influence of distortion, there are certain requirements for the length of the flowmeter to be installed in the front and rear straight pipe sections, otherwise the measurement accuracy will be affected (a speed flow device can also be installed, try to avoid installing it after the nearest regulating valve and half-open valve).

Requirements for process pipes The flowmeter has certain requirements for installation in the upstream and downstream process pipes, otherwise the measurement accuracy will be affected. a. The inner diameter of the upstream and downstream process pipes is the same as the inner diameter of the sensor, and should be Satisfaction: 0.98DN≤D≤1.05DN (in the formula, DN: the inner diameter of the sensor, D: the inner diameter of the process pipe) b. The process pipe and the sensor must be concentric, the coaxial deviation is not greater than 0.05DN3, and the requirements of the bypass channel In order to facilitate the maintenance of the flowmeter, it is best to install a side channel for the flowmeter. In addition, for heavily polluted fluids and flowmeters that need to be cleaned and the fluid cannot be stopped, a bypass channel must be installed. 4. According to the requirements of the flowmeter on the pipeline The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
