The use of orifice meter scale several installation considerations

Abstract: the use of orifice meter scale several installation note information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Orifice meter installation considerations flowmeter expert introduction the basic requirement of orifice meter installed to complete each equipment should be checked first, ensure smoothly under the car. 1, the orifice plate before installation should check the throttle device number and size is in line with the pipeline. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the use of orifice meter scale several installation considerations article details. Orifice meter installation considerations flowmeter expert introduction the basic requirement of orifice meter installed to complete each equipment should be checked first, ensure smoothly under the car. 1, the orifice plate before installation should check the throttle device number and size is accord with the requirement of pipe installation location. 2, new piping system, must be conducted after washing and sweep line pipe orifice plate installation. 3, pay attention to the direction of orifice plate installed & other; +” Number should be toward a beam. Two, when installation should note 1, orifice plate center and the center line of the pipeline, concentricity error must not exceed 0. 015 ( 1 /β - 1) The numerical values. 2, orifice plate in the pipe installation shall guarantee that the transverse and perpendicular to the pipe axis perpendicularity error must not exceed & plusmn; 1° 。 3, 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. 4, orifice plate installation area must be tight, there is no leakage phenomenon exists. Therefore, the installation work must be conducted before the pipeline pressure test. 5, guide pressure pipe should be vertical or inclined, laying the inclination shall not be less than 1:12. 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 installed gas collector and settler respectively. 6, 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. 7, orifice plate installed in a vertical path of the director, take pressure position, can take on any pressure device in the plane of arbitrary choice. The main channel of orifice plate installed in horizontal or inclined, apply pressure mouth position as shown in figure 4. 8, guide according to the nature of the measured medium pressure tube and selection pressure, corrosion resistant materials, the inner diameter shall not be less than 6 mm, length zui to 16 meters. Given in table 2 when the different media guide pipe inner diameter and length, are available as a reference. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
