Both turbine flowmeters and vortex flowmeters are commonly used flow measurement instruments, characterized by precision measurement, simple operation, stable performance, and long service life. However, there are some distinctions in their usage.
A turbine flowmeter primarily focuses on measuring liquids. The turbine flowmeter is a velocity-type flow meter that works on the principle of the relationship between the rotational angular velocity of an impeller placed in the liquid and the flow rate of the liquid. It calculates the liquid flow rate by measuring the impeller's rotational speed.
On the other hand, a vortex flowmeter is designed based on the Karman vortex street principle. It uses fluid oscillation principles to measure flow. When the fluid passes through the vortex flow transmitter in the pipeline, two rows of vortices proportional to the flow rate are alternately generated behind the triangular prism vortex generator. The vortex shedding frequency is related to the fluid's average speed flowing through the vortex generator and the characteristics of the vortex generator.
Turbine flowmeter: It is widely used to measure petroleum, organic liquids, inorganic liquids, liquefied gases, natural gas, gas, cryogenic fluids, and other substances. It features a simple structure, few machining parts, lightweight, easy maintenance, large flow capacity (large flow at the same caliber), and adaptability to high parameters (high temperature, high pressure, and low temperature).
Vortex flowmeter: It is mainly used for flow measurement of industrial pipeline media such as gas, liquid, and steam. Its characteristics include small pressure loss, large measurement range, high precision, and almost no influence from fluid density, pressure, temperature, viscosity, and other parameters when measuring operating volume flow. With no moving mechanical parts, the vortex flowmeter has high reliability and requires minimal maintenance. Its instrument parameters can remain stable over a long period.
