Do you know the measurement range of vortex flowmeter?

The measurement range of vortex flowmeter is relatively wide and can be applied to flow measurement of various liquids and gases. However, the specific measurement range may vary due to factors such as measurement medium, pipe diameter, and environmental conditions. The following is a detailed introduction: Industrial water full tube vortex flowmeter is mainly used for flow measurement of small and medium pipe diameters, while plug-in vortex flowmeter can be used for flow measurement of large pipe diameter (DN ≥ 300mm) pipelines.. It is widely used in urban water pipelines and industrial water main pipelines of chemical, power, metallurgical, papermaking, chemical fiber and other enterprises, and can measure the circulating water, wastewater, waste reporting liquid, etc. in the production process. Corrosive liquids, such as sulfuric acid, hydrochloric acid, nitric acid, acetic acid, and various chemical solutions, can be accurately measured by vortex flowmeters. In recent years, vortex flowmeters with small diameters (DN ≤ 25mm) have become more suitable for measuring corrosive liquids. These flowmeters use compression molding technology, sensors are made of all plastic products, and are equipped with non-contact ultrasonic detection elements, achieving non-contact measurement of liquids. Electromagnetic flow meters dominate the flow measurement of non-conductive liquids, but vortex flow meters have significant advantages in flow measurement of non-conductive liquids, such as pure water and ultra pure water in the semiconductor industry. Oil products can be used for flow measurement of some low viscosity oil products, such as gasoline, kerosene, dies

el, as well as heavy oil and residue oil with reduced viscosity after heating. The gas measurement range vortex flowmeter is suitable for flow measurement of various gases, including air, oxygen, nitrogen, coal gas, natural gas, chemical gases, etc. However, for gas measurement, the technical parameters (such as accuracy level) of vortex flowmeter may differ from liquid measurement. The remote compensation type vortex flowmeter is mainly used for measuring saturated steam in pressure or temperature compensation mode. Measurement range limiting factors include fiber closure Reynolds number and medium flow velocity: The Reynolds number Re must be above 10000, and the medium flow velocity cannot be too low to prevent the sensing element from having a corresponding response due to insufficient vortex strength. Meanwhile, the vortex frequency will affect the signal processing, and the response frequency of the sensor and the frequency of the circuit will affect the lower limit of the measurement range. Therefore, when designing a vortex flowmeter, it is necessary to calculate the flow velocity of the fluid. On site environmental conditions: On site environmental conditions such as temperature, humidity, and electromagnetic interference may also affect the measurement accuracy of vortex flowmeters. Therefore, when selecting the type of flowmeter, these factors should be comprehensively considered to ensure the accuracy and reliability of the measurement results.
