About the choice of vortex flowmeter selection
Many of the problems in the actual application of the instrument are related to the selection and misuse of the instrument. After more than two years of use of the vortex flowmeter, we have learned a lot in its selection and use. These are crucial for selecting vortex streets and increasing measurement accuracy in the future.
1. The flowmeter diameter should be selected according to the actual conditions of the process. Under normal circumstances, the diameter of the selected instrument should be such that the minimum flow velocity of the gas is not less than 7m/s and the liquid flow velocity is not less than 0.7m/s.
2. In actual production, the design pipeline is generally too large, so the actual fluid flow will be too small. If the vortex diameter is selected according to the original pipeline, the measurement will be inaccurate or even impossible to measure. Therefore, the lower limit of the vortex flowmeter Determination is crucial. Only when the lower limit flow rate is determined can the most suitable vortex street be selected.

3, try to avoid the normal flow generated frequency of about 50Hz, because such power frequency interference into the instrument is not easy to be noticed, will cause measurement error.
