What are the factors affect scale vortex flowmeter metering precision

Abstract: what are the factors influence the measuring accuracy of vortex flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Now we face the most users are using vortex flowmeter measurement of steam flow, today we will give priority to with saturated steam to analysis together with everybody steam of vortex street flowmeter accuracy exactly what factors influence. Problem analysis and solution:. More flow meter manufacturers choose model price quote you are welcome to inquire, here is what are the factors influence the measuring accuracy of vortex flow meter scale article details. Now we face the most users are using vortex flowmeter measurement of steam flow, today we will give priority to with saturated steam to analysis together with everybody steam of vortex street flowmeter accuracy exactly what factors influence. Problem analysis and solution: 1, the steam is dry humidity analysis: in the steam containing water have an effect on accuracy of vortex flowmeter is 'the article we have introduced not contain too much water into steam, steam dryness under 85%. Solution: when steam humidity higher than 85%, in 7 d - meter exports Humidity transmitter 8 d. 2, excessive saturated steam pressure variation analysis: in the industrial field of normal pressure changes in the change in pressure is directly resulted in the density of saturated steam, when the pressure fluctuation value is higher than the rating, will directly affect the flow numerical height; Solution: because the density of saturated vapor pressure and temperature are one-to-one correspondence, so we according to the change of pressure correction of density compensation method based on look-up table segmented correction 3, instrument installation of pipeline vibration analysis: larger installation without reinforcement, pipe when the vibration is larger, results in higher flow value solution: strengthening four triangular, steam pipe exports to atmospheric vortex flowmeter analysis: when flowmeter export to the atmosphere, will appear before and after the pressure difference is too big, easy to achieve flow velocity limit; Solution: need to strictly control the saturated steam velocity makes it less than the maximum velocity of flow meter, or on the sides of vortex flowmeters are 5 rectifier, steam straight pipe before and after the installation of the wrong analysis: when the straight pipe before and after the meter is not in conformity with the requirements, the measuring principle of vortex flowmeters can be concluded that the distance is not in conformity with the requirement to reach vortex formation of the necessary conditions for the solution: straight pipe before and after the steam of vortex flow meter distance must be installed in strict accordance with the requirement to summarize: when the user after the purchase of vortex street flowmeter, during the installation process of Shanghai quality instrumentation engineers strong mind, read the instructions before installation, to avoid the unnecessary factors before and after the installation work above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
