What is the measurement range of DN65 vortex flowmeter? The measurement range of DN65 vortex flowmeter is usually between 0.1 and 100m3/h. The specific measurement range may vary due to the following factors: model differences: DN65 vortex flowmeters with different liquid numbers may have different measurement ranges. Manufacturer differences: The varying levels of craftsmanship and design standards of different manufacturers may result in differences in measurement ranges. Fluid properties: The density, viscosity, and other properties of the fluid may affect the measurement range of the vortex flowmeter. Pipeline conditions: Pipeline diameter, flow velocity, and other conditions may also affect the measurement range. Therefore, when choosing a DN65 vortex flowmeter, it is necessary to select the appropriate model and measurement range based on the actual measurement requirements and fluid properties, combined with the product information provided by the manufacturer. Meanwhile, during use, attention should also be paid to the installation and usage conditions of the vortex flowmeter to ensure the accuracy and reliability of the measurement results.

3. Vortex flowmeter flow calculationThe flow calculation of a vortex flowmeter is mainly achieved through the following steps and formulas: measuring the frequency of vortex occurrence: The vortex flowmeter 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 vortex 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 condi
