Flow meters with oval gear PPО
The principle of flow meter operation with oval pinions is following Two pinions the oval form, rotating under action of liquid flow and being in gearing, measure at each revolution some volume of liquid. Rotation of pinions are transferred to the accounting mechanism, being transformed in units of volume.
