2. Can a vortex flowmeter be used for water measurement?
A vortex flowmeter can be used for measuring water inside a casing.
. 1. Principle Applicability: The vortex flowmeter operates based on the Karman vortex principle. When water flows thro_600x400.jpg)
2. In practical applications, it is commonly used in circulating water systems and cooling water monitoring in industrial fields, and can be used for tap water measurement in civilian fields, covering production and daily life scenarios
3. Advantageous body dispersion and high measurement accuracy: the accuracy of water flow measurement is usually within ± 1% R to ± 1.5% R. Strong reliability: no moving parts structure, stable long-term operation • Wide range ratio: to meet the measurement needs of different flow rate conditions, attention should be paid to water temperature, pressure, and impurity content, which may affect the measurement results. In practical applications, corresponding models should be selected according to the characteristics of water quality.
3. Actual flow rate of vortex flowmeter
The flow formula measured by vortex flowmeter is qv=π D2U/4=π D2mdf/4Sr K=f/qv=[π D2md/4Sr] -1. Under specific flow conditions, a part of the fluid kinetic energy is converted into fluid vibration, and the vibration frequency of the vortex flowmeter is proportional to the flow rate (flow rate). A flowmeter that works based on this principle is called a fluid vibration flowmeter.
. At present, there are three types of fluid vibration flow meters: vortex street flow meters, vortex precession flow meters, and jet flow meters. Fluid vibration flowmeter has the following characteristics: 1) The output is a pulse frequency, which is proportional to the act
