Guide: how to choose the right gas turbine flow meter?

With the continuous development of science and technology, gas turbine flowmeters are more and more widely used. It is very important to choose a suitable gas turbine flowmeter, so how to choose?

Gas turbine flowmeter is mainly used for flow measurement of air, nitrogen, oxygen, hydrogen, biogas, natural gas, steam and other medium fluids in industrial pipelines. Impact. No moving mechanical parts, so high reliability and low maintenance. Instrument parameters can be stable for a long time. The gas vortex flowmeter adopts piezoelectric stress sensor, which has high reliability and can work in the working temperature range of -20℃~+250℃. There are analog standard signals and digital pulse signal outputs, which are easy to use with digital systems such as computers. It is a relatively advanced and ideal flow meter.

In addition, the pulse frequency signal output by the gas vortex flowmeter is not affected by changes in the physical properties and components of the fluid, that is, the instrument coefficient is only related to the shape and size of the vortex generator and the pipeline within a certain Reynolds number range. However, as a flowmeter, it needs to detect mass flow in material balance and energy measurement. At this time, the output signal of the flowmeter should monitor the volume flow and fluid density at the same time. The physical properties and components of the fluid have a direct impact on the flow measurement.

The gas vortex flowmeter is a new type of flowmeter that measures fluid flow in closed pipelines based on the Karman vortex principle. Because of its good medium adaptability, it can directly measure the volume flow of steam, air, gas, water and liquid under working conditions without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volume flow and mass flow under standard conditions. An ideal alternative to the type flowmeter.

Gas turbine flowmeter choosing method 

With the continuous development of science and technology, gas turbine flowmeters are more and more widely used. It is very important to choose a suitable gas turbine flowmeter, so how to choose?

First of all, the first thing to consider when choosing a gas turbine flowmeter is the accuracy of the instrument. As a measuring element, the accuracy of the gas turbine flowmeter is a very important factor. The higher the accuracy of the gas turbine flowmeter, the stronger the induction line to the surrounding environment, and the higher the requirements for the environment.

Secondly, the range should be considered, which refers to the flow range of the gas. When the gas flow is too large, the entire instrument will be damaged, so if the wrong flow measurement range is selected, the gas turbine flowmeter will be damaged. Therefore, the selection from the range range is also an important factor. The above are the points that need to be paid attention to when choosing a gas turbine flowmeter. As long as these considerations are followed, you can choose a gas turbine flowmeter that suits your work needs.

Turbine gas meter application

As a precision flow measuring instrument, it can be used to measure the flow and total amount of liquid together with the corresponding flow accumulating instrument. The gas turbine flowmeter is widely used in the measurement and control systems of petroleum, chemical, metallurgy, scientific research and other fields. It is important to choose the right gas turbine flowmeter.

The gas turbine flowmeter is an instrument for measuring the volume flow of gas. It consists of a flow detection part connected to the pipeline, a signal processing circuit and an indicating device. This type of instrument is mainly used for the measurement of medium and fluid in industrial pipelines, trade settlement and control in the chemical production process.

It is widely used in many fields such as petrochemical industry and metallurgical industry. Introduction Gas turbine flowmeter is an instrument for measuring the volume flow of gas. It consists of a flow detection part (usually a disc-shaped rotor) connected to the pipeline and a power conversion mechanism (motor or electromagnetic clutch) connected to it, and the display instrument consists of three parts.

Flue gas flow meter features

1. Small pressure loss:

The head loss that occurs when the fluid passes through the flowmeter is constant and can be ignored.

2. Good repeatability:

Designed with advanced ultra-low power single-chip microcomputer technology, it has the characteristics of zero point stability and accurate nonlinear correction; at the same time, a new signal processing amplifier and a unique filtering system are used to effectively eliminate the influence of interference pulses on the measurement; Therefore, its repeatability is good.

3. High reliability:

The key parts of the whole machine are all imported products from internationally renowned companies, and are equipped with a fully automatic intelligent calibration system that is carefully debugged to ensure the long-term stability of the whole machine; The electrical protection function fully guarantees the safety of the instrument.

Scope of application This type of gas mass flowmeter has a very wide range of applications, such as the measurement of various hydrocarbon vapors in the process automation control system of the oil product metering station of the urban gas distribution station in the long-distance oil and natural gas pipeline project, and the crude oil distillation tower of the refinery. It can be used in the measurement of the oil and gas recovery system in the kettle, the measurement of c02 in the catalytic reforming device of the petrochemical enterprise, and the mass flow of the compressed air at the outlet of the air compressor of the air separation equipment of the chemical plant.
