Product Introduction<\/h4>\n

The flowmeter consists of a metering box and a pair of oval gears installed in the metering box, which form a sealed crescent-shaped cavity with the upper and lower covers (due to the rotation of the gears, it is not relatively sealed) as the calculation unit of one displacement.<\/p>\n

When the measured liquid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet drives a pair of gears to rotate continuously, and continuously transports the liquid measured by the crescent-shaped cavity to the outlet. The product of the number of revolutions of the oval gear and four times the displacement each time is the total amount of the measured liquid flow (see the figure for the principle). The flowmeter is mainly composed of a housing, a counter, an oval gear and a coupling (divided into magnetic couplings and axial couplings).<\/p>\n
