The gas turbine Flowmeter integrates the gas turbine flow sensor and the flow accumulator, and its working principle is as follows: when the air flow enters the flow meter, it first passes through the rectifier with special structure and accelerates, under the action of the fluid. the turbine overcomes the resistance moment and the friction torque begins to turn. When the torque reaches balance, the speed of the turbine is stable, the speed of the turbine is proportional to the gas flow, and the magnetic field is periodically changed by the magnet on the rotating transmitting disk, so that the pulse generator outputs a pulse signal whose frequency is proportional to the flow rate. The microprocessor in the flow accumulator counts the pulse signal and calculates the working condition flow, and accumulates at the same time to get the total working condition volume. The Flowmeter adopts micro-power design, the internal and external power supply is switched automatically, and the lithium battery power supply can be used for more than five years. The product is suitable for measuring and or testing the volume flow and total amount of industrial gas and city gas. The main performance parameters of the product meet the GB/T1894-2003/ISO9951:1993 standard, and the product implements the national verification regulation JJG1037-2008 "verification regulation of turbine Flowmeter" and the enterprise standard Q/TX11-2010 "gas turbine Flowmeter".
