Product Description

Overview
Gas turbine flowmeter is a velocity instrument. It has high accuracy, good repeatability, simple structure, wide measurement range, small size, light weight, small pressure loss, and easy to maintain. It can be widely used in petroleum, chemical industry, metallurgy, city gas pipeline network and other industries. It has been widely applied, especially in city gas metering, and the metering of transmission pipe network and gas regulator station.
 
Working Principle
Gas turbine flowmeter places turbine in the measured fluid, when the gas flows through the meter, the gas was accelerated and rectified under the action of the rectifier with the special structure. The impeller is rotated by the force that the gas acted on the impeller; the blade on the impeller makes the magnetic resistance of magnetic circuit change periodically. The angular velocity of impeller in a certain range of flow is proportional to the flow. On the basis of electromagnetic induction principle, the flow meter inducts the pulse signal which is proportional to the volume flow of the fluid, the signal will be amplified and rectified by the pre-amplifier then be accumulated by the single chip, displayed on the LCD screen and then the pulse signal will be also with the signal detected by the temperature and pressure sensor into the totalizer to do the accumulate processing, at last display the result on the LCD screen.
