1. What is the difference between vortex flowmeter and turbine flowmeter? "Answer from Hesheng Measurement and Control"

There are obvious differences between vortex flowmeter and turbine flowmeter in terms of working principle and applicable working conditions, as follows: Different working principles. Vortex flowmeter: works according to the Karman vortex principle. When the fluid passes through the vortex flow transmitter in the pipeline, two columns of vortices will alternate up and down behind the vortex generator in the triangular vortex column, and the release frequency of the vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator. By measuring the vortex frequency generated by fluid oscillation, the average velocity, flow rate, and volume of the fluid flowing through the vortex generator can be calculated. Turbine flowmeter: uses gas to drive the impeller of the flowmeter to rotate, and the speed of impeller rotation is proportional to the volume flow rate of the fluid. According to the principle of electromagnetic induction, a magnetic sensitive sensor is used to sense a pulse signal proportional to the volume flow rate of the fluid from the synchronously rotating impeller, and then the volume flow rate is calculated through calculation. Suitable for different working conditions, vortex flowmeter is mainly used for flow measurement of industrial pipeline medium fluids. The measurable medium types are diverse, covering various media such as gas, liquid, steam, etc. Characteristics of operating conditions: Small pressure loss, which means that there is less obstruction to fluid flow during the measurement process,

and it will not significantly increase the energy consumption of the system; Large measuring range, able to adapt to measurement needs of different flow rates; High precision, able to provide relatively accurate traffic data; When measuring the volumetric flow rate under working conditions, it is almost unaffected by parameters such as fluid density, pressure, temperature, viscosity, etc., which allows it to maintain good measurement performance even under complex working conditions; No movable mechanical parts, reducing measurement errors and maintenance costs caused by mechanical component wear and failure, high reliability, low maintenance volume, and long-term stability of instrument parameters. Turbine flowmeter is widely used in media such as petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas, and low-temperature fluids. Characteristics of working conditions: simple structure, few processed parts, which not only reduces production costs, but also makes equipment installation and maintenance more convenient; Lightweight, easy to transport and install; Easy to maintain, able to quickly repair and replace components when faults occur; Large circulation capacity, adaptable to high parameter measurement, and able to meet some industrial scenarios with high requirements for flow measurement.
