1,   Straight pipe section requirements In order to improve the effect of eddy current and flow field distortion, the flow meter is installed on the front and rear straight pipe sections with certain requirements, otherwise it will affect the measurement accuracy (it is also possible to install the flow distributor, and try to avoid after the * near-control valve and half-open valve installation).

In addition, if the heavy pollution fluid and the flowmeter need to be cleaned and the fluid cannot be stopped, the bypass channel must be installed. 4, in accordance with the requirements of the flowmeter on the pipeline CNC Machine For Tube Sheets,Machinery CNC Metal Tube Sheet,CNC Metal Laser Cutting Machine,Metal Tube Plasma Cutting Machine Shandong ShuoFang Environmental Technology Co., Ltd. , https://www.chinafincnc.com
