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. Flow Calculation of Vortex Flow Meter

The flow calculation of vortex flow meter is mainly achieved through the following steps and formulas: Measuring the frequency of vortex occurrence: The vortex flow meter first measures the frequency of vortex occurrence, which is directly related to the average flow velocity of the measured medium. The formula for calculating frequency is: f=Sr * U1/d=Sr * U/m, where Sr is the Strouhal number, reflecting the strength of the vortex; U1 is the average flow velocity on both sides of the v

ortex generator; D is the width of the upstream face of the vortex generator; M is the ratio of the bow shaped area on both sides of the vortex generator to the cross-sectional area of the pipeline. Calculate volumetric flow rate: The formula for calculating volumetric flow rate Li Zao is: qv=π * D2 * U/4=π * D2 * md * f/4 * Sr, where D is the diameter of the body. By using this formula, the measured vortex frequency can be converted into actual volumetric flow rate. Determination of instrument coefficient: The instrument coefficient hall disturbance K, which corresponds to the number of pulses per cubic meter of flow, is an important parameter for vortex flowmeters. The formula for calculating the instrument coefficient K is: K=)? 1. It reflects the characteristics of the flow meter. Considering calibration and compensation under different conditions: In practical applications, vortex flowmeters need to measure different parameters under standard and working conditions, such as volume flow rate, absolute pressure, thermodynamic temperature, and gas compression coefficient. These data help calibrate and compensate for the performance of flow meters under different conditions, ensuring measurement accuracy. In summary, the vortex shedding flowmeter achieves accurate measurement of flow rate by measuring vortex frequency, combined with pipeline size and specific coefficients. Meanwhile, considering calibration and compensation under different conditions is also an important step in ensuring measurement accuracy.
