What are the reasons for inaccurate measurement of vortex flowmeters?
The principle of inaccurate measurement of vortex street flowmeter may have the following factors
1. The selection of vortex street flowmeter is generally based on one diameter and one flow range. Therefore, when choosing a vortex street flowmeter, accurate and reliable parameters must be provided in order to select a suitable diameter vortex street flowmeter.
. If the diameter of the vortex street and the pipeline cannot match the stove god, it is recommended to use a variable diameter method to solve the problem.2、 In the case of flow fluctuations, the flowmeter may experience large fluctuations during measurement. Firstly, when installing the vortex flowmeter, it is necessary to ensure that the installation method is correct in order to ensure
3、 The influence of accumulation on the upstream surface of the vortex generator in a vortex flowmeter. If there are viscous particles in the measured fluid, they may gradually accumulate on the upstream surface of the vortex generator, causing changes in its geometric shape and scale, and therefore the flow coefficient will also change accordingly. Therefore, attention should be paid to this in application.
