What are the measurement ranges of vortex flowmeters?

1、 Vortex flowmeter is a flowmeter based on the Karman vortex principle for measurement. It can measure liquids and gases, and is also very economical. The diameter is generally DN10-- DN1000. With temperature and pressure compensation, it can accurately measure gas or steam flow, and has a wide range of applications;

2、 Vortex flowmeter can only measure volumetric flow rate, usually in m3/h (cubic meters per hour), with instantaneous flow display and cumulative flow display;

3、 The measurement range corresponding to electromagnetic flow meters of different diameters is: liquid measurement: (unit: m3/h): DN15

1.2-6; DN20

1.5---10； DN25：2---16； DN32

1.8---20； DN40：2.5---25； DN50：3.5---40； DN65：7.5---70； DN80：12---130； DN100：18---160； ..... Gas measurement: (unit: m3/h): DN15:4--28; DN20：6---40； DN25：8---50； DN32：15---150； DN40：18---180； DN50：25---480； DN65：50---500； DN80：80---800； DN100：120---1200； .....

2. Calibration of Vortex Flow Meter

The calibration of vortex flow meters is an important step to ensure their accuracy and legality during use, mainly carried out through two methods: the standard meter method and the 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. Advantag

es: Installed in a closed system, it can reduce time measurement errors; Having the advantages of online verification and serving 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.
