1. The difference between turbine flowmeter and vortex flowmeter
1. The design principles of turbine flowmeter and vortex flowmeter are different. Turbine flowmeter is mainly used for measuring liquids, and it is a velocity flowmeter. Its working principle is based on the relationship between the rotational angular velocity and flow velocity of the impeller in the fluid, and the flow rate of the liquid is determined by measuring the rotational speed of the impeller. The vortex flowmeter is manufactured based on the Karman vortex principle, which calculates the flow rate by measuring the vortex frequency generated by the fluid passing through a specific device in the pipeline. This frequency is related to the flow velocity and device characteristics. The application scope of the two flowmeters is also different. Vortex flowmeters are widely used in industrial applications to measure the flow of various media such as gases and liquids. Turbine flowmeters are suitable for flow measurement of various media such as petroleum, organic liquids, inorganic liquids, liquefied gas, and natural gas, as well as applications in special situations such as high temperature, high pressure, and low temperature conditions. The characteristics of turbine flowmeters and vortex street flowmeters are different. Turbine flow meters are favored for their simple structure, few components, light weight, easy maintenance, strong flow capacity (larger flow rate under the same diameter), and high parameter adaptability (such as high temperature, high pressure, and low temperature). The vortex flowmeter is known for its extremely small pressure loss, large range, high precision, and the advantage of being almost unaffected by parameters suc
2. Differences between turbine flowmeter and vortex flowmeter
There are significant differences between turbine flowmeter and vortex flowmeter in terms of design principles, application scope, and characteristics, as follows: Design principle Turbine flowmeter: belongs to velocity flowmeter, focusing on measuring liquids.. The principle is to use the relationship between the rotational angular velocity of the impeller placed in the liquid and the liquid flow velocity, and calculate the liquid flow rate by measuring the impeller speed. Vortex flowmeter: designed and manufactured based on the Karman vortex principle, using fluid oscillation principle to measure flow rate. When a fluid passes through a vortex sealed flow transmitter in a pipeline, two columns of vortices proportional to the flow velocity will alternate up and down behind the triangular vortex generator. The frequency of vortex release is related to the average velocity of the fluid and the characteristics of the vortex generator. Application scope: Turbine flowmeter is widely used for measuring objects such as petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas, and low-temperature flow sensors. Vortex flowmeter: mainly used for flow measurement of industrial pipeline medium fluids, suitable for various media such as gas, liquid, vapor, etc. Characteristics of turbine flowmeter: simple structure, few processed parts, ligh
