Orifice meter scale installation considerations, and take the installation of pressure

Abstract: the orifice meter scale installation considerations, and take the installation of pressure information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Orifice flowmeter is widely used in petroleum, chemical, metallurgical, power, light industry and other departments. Orifice meter ( Also known as the throttle device, differential pressure flowmeter) Is measuring the flow of differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter can be measured in the pipeline. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the orifice meter scale installation considerations, and take the installation of pressure mouth article details. Orifice flowmeter is widely used in petroleum, chemical, metallurgical, power, light industry and other departments. Orifice meter ( Also known as the throttle device, differential pressure flowmeter) Is measuring the flow of differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes. Orifice meter measuring system is installed, must meet the following technical requirements: 1) Orifice meter installation, his hole center and concentric pipe center axis, and its end face perpendicular to the pipe axis; 2) In orifice, the downstream side takes pressure hole axis in accordance with the distance from the hole board, downstream face is 25. 4± 0. The requirement of 8 mm; 3) Take the axis of the hole should be with the orifice of upstream and downstream side 2 d measuring tube length in the axis of the cylindrical vertical, apply pressure hole axis and the orifice plate facing slope Angle on both ends of the Angle is not more than 3 degrees. Take hole diameter should not be greater than zero. 08年d; 4) Orifice plate need straight pipe before and after installation, the length of the straight pipe upstream side plate with holes form of local resistance and diameter ratio & beta; Is related to the method for determining the following table: table. Between the orifice and choke the required length of straight pipe ( No flow regulator) Orifice meter application because of the measured medium, different installation time take the position of the pressure also has the corresponding change, is 1, the current body of liquid, in order to prevent the bubble into the guide tube, apply pressure should be in the process piping center line slants & le; 45° Position, take the positive and negative pressure in the mouth and pipeline symmetry position, both should be in the same horizontal plane; 2, be for the steam flow, should guarantee the condensate in the condenser surface is constant and the positive and negative of condensation on the tube surface height. Is symmetric suction mouth is in with the pipe position, both should be in the same horizontal plane. 3, be for gas flow, to prevent liquid ( Condensate) Enter the guide tube, apply pressure above should be in the process piping center line on-line partial & le; 45° Position, take the positive and negative pressure in the mouth and pipeline symmetry position, both should be in the same level; Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

However, with the increased prevalence of mass flow meter, it has become far more affordable.
