Vortex flowmeter is a commonly used flow measurement instrument, which works by measuring the oscillation frequency of the fluid under the action of the vortex to calculate the flow rate. In practical applications, the measurement accuracy of vortex flow meters is affected by various factors, including pressure, temperature, flow rate, etc.
When the actual pressure measured by the vortex flowmeter is higher than the design pressure, the accuracy of the flow measurement results may be affected. Specifically, as the pressure increases, the flow velocity and density of the fluid will change, which will affect the measurement results of the vortex flowmeter. In addition, when the pressure changes, the frequency response of the vortex flowmeter will also change, which may lead to measurement errors.
To ensure the measurement accuracy of the vortex flowmeter, it is recommended to perform necessary calibration and adjustment in practical applications.
During the calibration process, multiple calibrations can be carried out according to the different situations of design pressure and actual pressure to determine the accurate measurement value of the flowmeter at different pressures. In addition, other measures can be taken to reduce errors, such as installing pressure regulators to stabilize fluid pressure, or selecting vortex flow meters with higher measurement accuracy and pressure adaptability.
In summary,
when the actual pressure measured by the vortex flowmeter is higher than the design pressure, the flow measurement results may be affected. To ensure measurement accuracy, it is recommended to perform necessary calibration and adjustment in practical applications, and take other measures to reduce errors.
