Description High quality Oval gear mechanical oil flow meter
Oval gear flow meter is a pointer display .It is a kind of light volume flow meter of which the print wheel has cumulative count and zero. This flow meter is widely used in various industrial areas to control the liquid flow. It is applicable to all types of liquid measuring, such as crude oil, diesel, gasoso on, with great range and high precision, convenient use and maintenance. Different materials selected can meet the petroleum, chemical, rmaceutical, food, metallurgy, electricity, transportation and other fields of liquid flow measurement.

Features High quality Oval gear mechanical oil flow meter
Flow meter is installed in the metering tank and the measurement of a pair of oval box gear, with the upper and lower cover an early Lunar sealed cavity (due to rotation of the gear, so sealing is not an absolute) as a unit of emissions. When measured by the pipe into the liquid flow meter, due to pressure generated by the Import and Export Department to promote a pair of differential gears for rotation, the constant measurement by cavity after the beginning of the Lunar liquid delivery to the exit, elliptical gear with each revolution time displacement is the product of four times the measured volume of liquid flow (the principle of Figure 1).
