Principe<\/strong><\/h5>\n

Oval gear meter is generally comprised of a flow transducer and a counter mechanism. The main part of the
\ntransducer is a measuring chamber which consists of a pair of oval wheels and a sealing coupling. The counter
\nmechanism contains speed reduction gears, adjusting device, counter, and pulse transmitter etc.<\/p>\n

\"structure\"<\/p>\n

In the measuring chamber, a pair of oval wheels and cover plate make a crescent shape cavity which is used as
\na measuring unit. The oval wheels are rotated by the pressure difference in the inlet and outlet of the meter and drive
\nthe inlet liquid through the cavity to the outlet, each revolution of the oval wheels displaces fluid four time the volume
\nof the cavity, the total revolutions of the oval wheels and the revolution rate will be transferred to the mechanical
\ncounter, and the total liquid volume and instantaneous flow will be known by the pointer display and the roller
\nintegration. The attached signal generator converts the rotary axial angular shift to the pulse signal and then transmits
\nit to the electrical indicator for remote integrated flow and instantaneous flow indication and control.<\/p>\n
