Nutating DiscNutating Disc Nutating Disc Nutating Disc Principle of Operation

Liquid enters a precision-machined chamber containing a disc which nutates (wobbles).The position of the disc divides the chamber into compartments containing an exact volume.Liquid pressure drives the disc to wobble and a roller cam causes the nutating disc to make a complete cycle.The compartments are filled and emptied each cycle.The movements of the disc are transmitted by a gear train to a register/totalizer or pulse transmitter.Close clearances between the disc and chamber ensure minimum leakage for accurate and repeatable measurement of each volume cycle.
