1. Will there be fluctuations during the blowing process of liquid flow using a vortex flowmeter?

Vortex flowmeters used for liquid flow measurement will inevitably experience fluctuations in flow readings during the blowing process, and the amplitude and frequency of the fluctuations are directly related to the pressure, flow rate, and residual impurities in the pipeline of the blowing airflow..

1. Core causes of fluctuations (1) Fluid working conditions deviating from normal production state 1 The vortex flowmeter calculates the flow rate by detecting the frequency of vortex shedding generated when the fluid passes through the vortex generator. Normally, when measuring liquids, the fluid is a continuous and stable flow, and the law of vortex shedding is fixed. When blowing, compressed air or nitrogen is generally used. The flow rate of the sliding airflow will quickly increase from low to the design value, and the supply pressure often fluctuates. The frequency of vortex shedding changes in real time with the flow rate, and the displayed value naturally fluctuates. 2. The blowing airflow will also carry residual condensate, rust slag, and welding slag in the pipeline, which will disrupt the stable generation of vortices and further amplify the fluctuation amplitude. （2） Intermittent characteristics of blowing operation 1 On site blowing mostly adopts the method of intermittent valve opening and closing, and the airflow for a single blow flows in a pulse like manner. The flowmeter reading will show intermittent peaks and drops with the interruption of air flow, forming regular fluctuations.

2. Actual Explanation of Fluctuations 1 If a stabilizing tank and a precision throttle valve are inst

alled in the gas supply system to stabilize the airflow pressure before blowing and blindly sweeping, the fluctuation amplitude will be significantly reduced, but it cannot be completely eliminated because the blowing itself belongs to a non steady state working condition. 2. The fluctuation of the reading during this blowing is a normal phenomenon and should not be judged as a flow meter failure. After the blowing is completed and the pipeline returns to normal liquid and gas working conditions, the accuracy of the flow meter can be verified again.
