For the diversity of industrial flow measurement instrumentation equipment, when using industrial instruments. Choosing to use different instrumentation equipment due to different application environments can also be said to be a form of choosing instrumentation now. With a variety of similar but different meters, the user is bound to utilize the wrong choice. For example, turbine and vortex flowmeter, which are often mistaken by enterprises, what is the difference between them before?
1. Differences in application areas
Vortex flowmeter: mainly used for flow measurement of medium fluid in industrial pipelines, such as gas, liquid, steam and other media. It is characterized by small pressure loss, large measuring range, high precision, and is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc. when measuring the volume flow of the working condition. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time.
Turbine flowmeter: widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas, coal gas and cryogenic fluids and other aspects. It has the advantages of simple structure, few processing parts, light weight, convenient maintenance, large flow capacity (large flow through the same caliber) and adaptable to high parameters (high temperature, high pressure and low temperature).
Second, the difference between production and manufacturing
A turbine flowmeter is an instrument that uses a multi-blade rotor (turbine) to measure the average flow of a fluid and calculate flow or total flow from it.
The vortex flowmeter is designed and manufactured according to the principle of Karman vortex. The flow rate is measured using the principle of fluid oscillation. When the fluid passes through the vortex transmitter in the pipe, the triangular column vortex generator alternately generates two rows of vortices in proportion to the flow. The release frequency of the vortex generator is related to the average velocity of the fluid flowing through the vortex generator and the characteristics of the vortex generator
3. Differences in data transmission
The turbine flowmeter cuts off the magnetic induction line through the rotation of the impeller, and then measures the output flow through signal processing.
