2 Working principle
Gas turbine discharge meter is speed-measuring instrument. When the gas flow flow meter, by front-rectifier unit is accelerating and after rectification, overcoming friction resistance and fluid resistancedrove rotating screw linear turbine blades, in the context of certain flow, speed proportional to the velocity of the gas turbine blades. The turbine is rotating through the deceleration drive mechanism and magnetic coupling connecting output to install in the table take a meter reading external machinery unit, for the count and discharge pulse signals (LF or HF) output. |
