Oval Gear Flow meter
Oval Gear Flow Meter
Oval Gear Flow meters are the instruments, invented based on the positive displacement principle considering accuracy and precision as the core of their performance. These volumetric flow meters are best used in industries like oil and petroleum, chemicals, pharmaceuticals, general manufacturing industries where high level of accuracy and repeatability are required.
Operation Principal
Liquid Passes into the single case measuring chamber and displaces two oval gears. Each rotation of an oval gear is proportional to a discrete unit of volume. In turn, the speed at which the gears rotate is directly proportional to flow rate. Reed or Hall Effect sensors mounted outside the pressure boundary detect the movement of the oval gears, thus allowing local or remote instruments to dis-
Benefits
