We are pleased to introduce our new ACHIEVERS positive displacement flow meters kerosene orany slightly viscous noncorrosive liquids; this is reset type, mechanical flow metersApplication 3" fuel Flow meter is a kind of positive displacement meter tomeasure the liquid flow or instantaneous flow of the pipe tube.It is a kind of accumulate meter. Withcharacteristics of high accuracy, small change by the fluidviscosity, it is widely used to measure oil kind liquid, forbidden tomeasure corrosiveWorking PrincipleThe measurement part of 3" inch fuel flow meter is posed by twoelliptical gears mesh witheach other and its shell (measuring room).The flow meter works by two elliptical gears to mesh witheach other, its working process are as follows: the pressure of liquid from inlet side, to show theoutlet pressure, the bottom rotor has no rotating torque even it effected the liquid pressure, but theabove gears will move by the rotating pressure .In the status of the above gears driving gear,and the bottom gear is driven gear. both of these two gears have rotating torque by theliquid pressure, and they move with the direction of the arrow to spaceThe gear space isopposite to, the bottom gear is driving gear, and above gear is driven gear. The bottom gear pushesthe liquid out from the halfmoon space under the liquid press pushes liquid volume four times ofmeasurement room. So, as long as the rotation of gears, the liquid volume can be counted.
