Introduction: With the continuous development of science and technology, gas turbine flowmeters are more and more widely used. Choosing a suitable gas turbine flowmeter is very important, so how to choose?
The gas turbine flowmeter is mainly used for the flow measurement of air, nitrogen, oxygen, hydrogen, biogas, natural gas, steam and other medium fluids in industrial pipelines. When measuring the volume flow of working conditions, it is almost independent of the fluid density, pressure, temperature, viscosity and other parameters. Impact. There are no movable mechanical parts, so the reliability is high and the maintenance is small. The 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℃. It has analog standard signal and digital pulse signal output. It is 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 the change of fluid physical properties and composition, that is, the meter 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 flow meter, it is necessary to detect the mass flow in material balance and energy measurement. At this time, the output signal of the flow meter should monitor the volume flow and fluid density at the same time. The physical properties and components of the fluid still have a direct impact on the flow measurement.
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 without temperature and pressure compensation. Equipped with temperature and pressure sensors, it can measure the volume flow and mass flow under standard conditions, which is throttling. The ideal substitute product of type flowmeter.
With the continuous development of science and technology, gas turbine flowmeters are more and more widely used. Choosing a suitable gas turbine flowmeter is very important, 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, it is necessary to consider the range, which refers to the flow range of the gas. When the flow of gas is too large, it will cause damage to the entire instrument. Therefore, if the wrong flow measurement range is selected, it will cause damage to the gas turbine flowmeter. So choosing from the range of range is also an important factor. The above are the points that need to be paid attention to when selecting a gas turbine flowmeter. As long as these considerations are followed, you can choose a gas turbine flowmeter suitable for your own work requirements.
As a precision flow measuring instrument, it can be used to measure the flow and total amount of liquid when matched with the corresponding flow totalizer. The gas turbine flowmeter is widely used in the measurement and control system of petroleum, chemical industry, metallurgy, scientific research and other fields.
