The Working Principle Of Elliptic Gear Flowmeter

Working principle: When the measured liquid enters the flow time through the pipeline, the pressure difference generated at the inlet and outlet drives a pair of gears to rotate continuously, and continuously transfers the liquid measured by the initial moon-shaped cavity to the outlet. The number of revolutions of the elliptical gear and the product of four times of each displacement is the total amount of the measured liquid flow.

Operating characteristics:

(1) Flow measurement has nothing to do with the flow state of the fluid; The larger the viscosity of the medium, the smaller the leakage from the gear and metering space clearance, so the larger the viscosity of the nuclear measuring medium, the smaller the leakage error, the more favorable for measurement; (2) The elliptical gear flowmeter has high measurement accuracy and is suitable for the measurement of the flow of high viscosity medium, but it is not suitable for the fluid containing solid particles (solid particles will jam the gear, so that the flow can not be measured). If there is gas in the liquid medium, the measurement error will also be caused.
