Will the flange leakage of the vortex flowmeter show negative pressure?

Air leakage from the vortex flowmeter flange will affect the measurement results of the flowmeter, but generally it will not display negative pressure.

1. The working principle of the vortex flowmeter

The vortex flowmeter is a flowmeter based on physical principles. Its working principle is generated by the rotation of a turbine under the action of fluid. The frequency is changed to measure the flow rate and flow rate of the fluid. The vortex flowmeter is mainly composed of the flowmeter body, turbine, components and signal extraction device.

In the vortex flowmeter, the fluid enters from the inlet of the flowmeter body and passes through the turbine in the flowmeter body. The turbine rotates with the impact of the fluid, and the frequency change generated during the rotation is taken out by the signal. Once the device or converter is resolved, the flow rate and flow rate data for the fluid can be obtained.

2. The impact of flange leakage on the vortex flowmeter

When there is air leakage in the flange of the vortex flowmeter, it will affect the measurement results of the flowmeter. certain influence. Air leakage will cause the fluid to form a certain negative pressure area at the inlet and outlet of the flow meter. This negative pressure area will reduce the measurement range of the flow meter and affect the flow of the fluid, thereby changing the rotation frequency of the turbine and causing the measurement results of the flow meter. There are certain errors. When the air leakage is large, the vortex flowmeter will be unable to measure correct flow data.

3. Will the leakage of the vortex flowmeter flange display negative pressure?

The display screen of the vortex flowmeter will generally display the flow value and flow rate value, rather than the negative pressure value. . When there is air leakage in the flange of the vortex flowmeter, the vortex flowmeter will only measure the actual fluid flow passing through the flowmeter, but not the negative pressure value.

Therefore, under normal circumstances, air leakage from the vortex flowmeter flange will not show negative pressure, but will affect the measurement accuracy and accuracy of the flowmeter.

In summary, air leakage from the vortex flowmeter flange will have a certain impact on the measurement results of the flowmeter, but generally it will not display negative pressure. In order to ensure the measurement precision and accuracy of the vortex flowmeter, the flange of the vortex flowmeter should be checked regularly for air leakage, and maintenance and repair should be carried out in a timely manner to ensure the normal operation of the flowmeter.
