What is vortex flow meter let aluminum alloy pipeline manufacturers for your introduction

The upper limit of the vortex flow meter is applicable to the flow rate which is generally not calculated. The calculation of the lower limit flow should satisfy two conditions: the Reynolds number should not be lower than the limit Reynolds number (Re=2×104); The vortex intensity generated by the stress vortex flow meter at the lower limit of flow should be greater than the allowable value of the vortex intensity of the sensor (vortex intensity is proportional to the lift force of rho v2).


In many years of verification work of aluminum alloy piping manufacturers, we found that someone used a loophole of the steam vortex flowmeter, and only made an issue at the steam outlet while keeping the measuring pipe section of the vortex flowmeter intact, which could lead to the measurement of serious deviation of the vortex flowmeter measurement. The difference is only 0.42%, with good linearity, and the measurement accuracy is up to ± 0.5% f. S. The sensor can be used in high temperature, strong radiation, strong magnetic field interference and corrosive environment such as chemical industry, mining, nuclear power and other fields of all kinds of gas and liquid flow


According to the manufacturer of aluminum alloy piping, the volume flow rate of vortex street flowmeter under working condition is not affected by the temperature, pressure, density and other thermal parameters of the measured flow body, but the final measurement result of liquid or steam should be the mass flow rate, and for gas, the final measurement result should be the standard volume flow rate. The mass flow rate or standard volume flow rate must be converted by fluid density, and the fluid density change caused by fluid condition change must be considered.


The main factors causing the flow measurement error are: the measurement error caused by uneven pipeline velocity; The medium density when fluid condition changes cannot be determined accurately. Wet saturated steam was assumed to be dry saturated steam for measurement. If these errors are not limited or eliminated, the total measurement error of vortex flowmeter will be very large.


Instrument selection is very important work in instrumentation, instrument selection, whether correctly or not will directly affect the instrument can normal operation. So the user when choosing the company's products and design unit, please read this section data, the process parameters of fluid should be carefully checked and can at any time to contact my company's sales or technical support department, to ensure that the correct selection.
