Orifice plate steam gas flow meter scale correction

Abstract: the orifice steam gas flow meter scale correction information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Master flowmeter flow coefficient correction method; To understand the relationship between the flow coefficient and its influence factors. Second, the experiment principle of engineering by measuring the velocity and flow rate is determined by the fluid pressure difference. Orifice gas flowmeter mathematical model of steam. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a orifice plate steam gas flow meter scale calibration article details. Master flowmeter flow coefficient correction method; To understand the relationship between the flow coefficient and its influence factors. Second, the experiment principle of engineering by measuring the velocity and flow rate is determined by the fluid pressure difference. Orifice mathematical model for the steam gas flowmeter: steam orifice flowmeter is based on the fluid flow in the process of energy conversion, the fluid through the orifice differential pressure before and after the change to determine the flow of fluid through the pipe cross section. Because of the 2 - 2 ( Vena contracta) Place area is difficult to determine, so engineering with orifice velocity u0 instead of u2, the fluid through the orifice resistance losses from time to tome, for flow and change the vena contracta position of the measured ( P1 - P2) /ρ Deviation, so through the experiment to determine C0, the calculation formula of flow meter: steam orifice flowmeter deficiency is large in the resistance loss and the loss can be measured by the u-shaped pressure differential gauge. Water tank 2. Regulator is 4. 8 orifice steam flowmeter. Centrifugal pump main parameters: the pipe diameter: 27 mm; Balancing valve opening differential pressure meter, close the purge valve. Start the circulating pump. Exhaust: ( 1) Exhaust pipeline; （ 2) Pressure pipe exhaust; （ 3) Close the balance valve and slowly turn on the differential pressure gauge valve, eliminate the bubbles on the differential pressure gauge, note: the first rank in the back pressure pipe of low pressure pipe. Read the pressure differential meter zero value. Open valve to zui, determine the flow range, determine the laboratories, determination of pressure drop before and after the orifice plate and through the orifice plate brought about by the pressure drop. Determination of reading: the change of the pipeline flow, read out a series of flow, pressure difference. Experimental apparatus restorable, open the balance valves on the pressure differential gauge, and cleaning up. Five, the experimental record number flow orifice pressure drop (resistance losses L/S） Left right left reading right reading six, experiment report, data sorting sequence number 1 velocity u1Red = du1 & rho; /μ Pump C0 * loss & xi; In this experiment, and for a specific orifice m is constant, the type can be written. The experimental data obtained will be set on semilog coordinate C0 ~ Red curve drawing graphics, which can determine the orifice C0 and orifice flow coefficient of the orifice plate on the project of the measurement range. This article from: steam flow meter above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
