Orifice meter scale when using pipeline installation requirements

Abstract: the orifice meter scale installation pipeline requirements when using information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Orifice flowmeter is widely used in petroleum, chemical industry, metallurgy, electricity, heating, water supply in areas such as process control and measurement. Meter should be checked carefully before installation standard orifice plate number, number, specifications and pipeline condition and parameters such as flow range. More flow meter manufacturers choose model price quote you are welcome to inquire, below is the orifice meter scale installation pipeline requirements when using the article details. Orifice flowmeter is widely used in petroleum, chemical industry, metallurgy, electricity, heating, water supply in areas such as process control and measurement. Meter should be checked carefully before installation standard orifice plate number, number, specifications and pipeline condition and parameters such as flow range. In selecting pressure near the mouth with & other; +” Should be at the end of the upstream section connection with liquid, marked & other; — ” Should be at the end of the downstream section connection with liquid. For new piping system, must first after scavenging the installation standard orifice plate, in order to prevent the tube sundry jam or damage standard orifice plate led to the decrease of the measurement accuracy. Standard orifice centerline should be with the pipe axis coaxial. Meter when installation should be equipped with a measuring tube, at least keep the top 10 dn, after 5 dn, such as straight pipe section, in order to improve the accuracy of measurement. If need to install the valve before and after the flowmeter to zui good choose gate and in the operation of the fully open; Regulator after 5 dn should be in the downstream piping. Pressure the inner diameter of the pipe and the pipe length and medium smudgy degree, usually within 45 meters in diameter of 8 - 12 mm pipe. Measuring the liquid flow guide pipe horizontal section should be in the same horizontal plane. If install throttle in the vertical pipe, distance between pressure spool apart ( Perpendicular direction) Have influence on the zero point, the differential pressure transmitter, should pass & other; Zero migration & throughout; To correction. Should have a strong pipeline bracket of socket, two get pressure piping should be close to each other as much as possible and away from heat source or vibration source, measurement of water vapor flow, application of thermal insulation material bind together, must be ( If the temperature below 0 ℃) Add trace pipe to prevent freezing. When measuring the dirt flow, should be attached isolator or settler. Bring pressure must always remain single-phase fluid in the pipeline. By measurement of body is a gas, pressure pipe ( Including differential gauge pressure chamber) All gas phase; By current body is liquid, pressure are all liquid in the pipeline, you must not have bubbles. Therefore it is necessary to introduce in pressure piping zui low drain valve or exhaust valve, zui highs in new clothes or differential pressure transmitter should pay special attention to all the time. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
