2. Calibration of vortex flowmeter

The calibration of vortex flowmeter is an important step to ensure its accuracy and legality in use. It is mainly carried out through two methods: standard meter method and bell jar method.

. Standard table method: Principle: Connect the vortex flowmeter as a standard with the tested flowmeter in series, and calculate the error of the tested flowmeter by comparing the readings of the two. Scope of application: Suitable for various fluids and liquids of different viscosities. Advantages: Installed in a closed system, it can reduce time measurement errors; Having the advantages of online verification and se Hefei vortex flowmeter

rving as a measurement standard for closed pipelines; High degree of automation, compact equipment, and low cost. Attention: The accuracy and stability of the standard table itself need to be regularly monitored. Bell jar method: Principle: The device based on lead stove and volumetric method calculates the flow rate by measuring the change in gas volume when the bell jar rises or falls. Scope of application: Suitable for calibrating air flow meters that are close to atmospheric pressure, such as gas meters and wet gas flow meters. The verification flow range is relatively small, with an accuracy between 0.2% and 0.5%. Attention: When using a water sealed bell jar for exhaust calibration, it is necessary to consider the possible errors caused by water vapor condensation when the temperature of the flowmeter being tested is lower than the water temperature. In practical applications, it is necessary to select an appropriate calibration method based on factors such as the usage scenario, fluid type, and calibration requirements of the vortex flowmeter.

3. What aspects should be paid attention to when installing a vortex flowmeter?

1: Effective measures should be taken for on-site environment and vibration: The ambient temperature of the vortex flowmeter is -40 ℃ ≤ T ≤ 55 ℃. If it is exposed to thermal radiation from production equipment, insulation and ventilation measures should be taken. Environmental air: Flow meters should not be installed in environments containing corrosive gases. If installation is necessary, ventilation measures must be taken. Mechanical vibration and impact: Vibration can generate interference signals. If the vibration and impact on the pipeline are strong and the medium flow rate
