The matters needing attention in the process of orifice meter scale installation

Abstract: the orifice meter scale installation matters needing attention in the process of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Many clients during the installation process, you will be careless, some do not pay attention to small details, can affect the use of orifice meter, the accumulation of long time also will appear all sorts of problems, first look at your measurement is a gas, liquid or steam. Gas pressure mouth zui fortunately. More flow meter manufacturers choose model price quote you are welcome to inquire, the following is the matters needing attention in the process of orifice meter scale installation article details. Many clients during the installation process, you will be careless, some do not pay attention to small details, can affect the use of orifice meter, the accumulation of long time also will appear all sorts of problems, first look at your measurement is a gas, liquid or steam. The upper gas mouth zui to take pressure pipeline; Liquid pressure on the side of the mouth but not in the right, of sedimentary particles can block the take pressure; Words of steam pressure in the tube side, 1, the orifice meter before installation should check the throttle device number and size is accord with the requirement of pipe installation location. 2, new piping system, must after washing and sweeping the pipe line for the installation of the orifice plate. 3, pay attention to the direction of orifice plate installed & other; +” Number should be thinking about flow velocity. 4, orifice plate center and the center line of the pipeline should be overlap, concentricity error must not exceed 0. 015 ( 1 /β - 1) The numerical values. 5, orifice plate in the pipe installation shall guarantee that the end face perpendicular to the pipe axis, perpendicularity error must not exceed & plusmn; 1° 。 6, clamping orifice plate with sealing gasket ( Including the ring chamber and orifice plate with flange, ring room) After the clamping, not into the pipe wall. 7, orifice plate installation must be tight, there is no leakage phenomenon exists. Therefore, the installation work must be conducted before the pipeline pressure test. 8, guide pressure pipe should be vertical or inclined, laying the slope shall not be less than 1:1. High viscosity fluid, the slope should also be increased. A cop pressure signal transmission distance is greater than 3 m, guide tube should be segmented tilt, and in all the zui high and zui low gas collector and settler respectively. 9, in order to avoid the differential signal transmission distortion, the positive and negative pressure guide tube should be close to laying, cold region also antifreezing measures should be taken. Can use electric heating or steam heat preservation, but to prevent overheating of measured medium vaporization and gas generated in the guide pipe fake differential pressure. 10, installation requirements of the orifice plate, and straight pipe length, don't know can ask manufacturer, or according to the former 20 d after 10 d to pack ( D refers to the orifice diameter) 11, plus or minus pressure leads to the guide of pressure pipe under any circumstances to keep parallel above is the orifice meter in some common problems in the process of installation, the hope can give you a help. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
