Comparison of Gas Turbine Flow Meter and Gas Precession Vortex Flow Meter

Abstract: The comparison information of gas turbine flowmeter and gas precession vortex flowmeter is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. At present, among the flow meters used for gas measurement in China, the gas turbine flowmeter is dominant, and the gas precession vortex flowmeter also has a certain market. The application occasions of the two are relatively similar, and users often have doubts about the choice of the two. Gas turbine flowmeter. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the comparison article details of gas turbine flowmeters and gas vortex flowmeters. At present, among the flow instruments used for gas measurement in China, gas turbine flowmeters are dominant, and gas precession vortex flowmeters also have a certain market. The application occasions of the two are relatively similar, and users often have doubts about the choice of the two. The gas turbine flowmeter is one of the main types of flowmeters. Its working principle is: the gas entering the gas turbine flowmeter is accelerated by the guiding fluid, and the accelerated gas acts on the blades of the turbine through the inlet channel, and the momentum of the gas makes The turbine of the flowmeter rotates in the flow path. Within a certain flow range, the number of revolutions of the turbine is proportional to the volume of the gas flowing through. Through the method of mechanical or electromagnetic induction, the number of revolutions f of the turbine can be obtained, so that the flow rate Q of the gas flowing through the flow meter can be obtained. Gas turbine flowmeters are widely used in the measurement of the flow or total amount of expensive gases such as gas, and are widely used in the measurement of natural gas flow at home and abroad. The theoretical research and practical experience of gas turbine flowmeters are very mature, there are corresponding international standards, and countries also have corresponding national standards, and my country has also adopted international standards. In Europe and the United States, gas turbine flowmeters are the most important gas flowmeters. In the Netherlands alone, more than 2,600 gas turbine flowmeters are used in natural gas pipelines. The gas precession vortex flowmeter is a flowmeter that began to appear in the 1970s. Its working principle is: the gas entering the gas precession vortex flowmeter is forced to rotate and accelerate after passing through the screw spinner, forming a vortex, a vortex of the vortex. The center is the vortex core. After the accelerated vortex enters the expansion section, it decelerates sharply, and the pressure rises to produce a backflow. Under the action of the backflow, the vortex core precesses spirally around the axis of the flowmeter. The flow rate Q can be deduced by measuring the vortex precession frequency f by the method of induction by the sensitive element. Gas precession vortex flowmeters are not widely used in foreign countries, but they are widely used in domestic natural gas and steam flow measurement. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Comparison of Gas Turbine Flow Meter and Gas Precession Vortex Flow Meter'
