The orifice meter scale installation requirements

Abstract: the installation requirements of orifice meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Orifice 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. Pressure the inner diameter of the pipe and the pipe length and medium smudgy range. More flow meter manufacturers choose model price quote you are welcome to inquire, here is the installation requirement of orifice meter scale article details. Orifice 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. 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. If need to install the valve before and after the orifice meter, zui good choose gate and in the operation of the fully open; Regulator after 5 dn should be in the downstream piping. 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. 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. Second, the orifice meter pipe installation check: before the orifice meter should be checked carefully before installation standard orifice plate number, number, specifications and pipeline condition and parameters such as flow range. Note that in selecting pressure near the mouth marked & 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. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.

In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , mass flow meter, endress hauser coriolis mass flow meter, and v shape coriolis mass flow meter are widely used.
