    • n operameter An instrument for indicating the number of movements made by a part of a machine, as the turns made by a shaft, the oscillations of a working-beam, the delivery of sheets from a printing-press, or the reciprocations of a cross-head, etc., in a stated interval of time. The principles of construction are various. A common form has a ratchet-wheel connected with registering-dials, and an oscillating lever which by suitable mechanism is made to take up a single ratchet-tooth at each to-and-fro movement of a reciprocating or oscillating part, such as the cross-head of a steam-engine. Another form has a spear-pointed spindle which is connected with a registering mechanism, the whole implement being held in the right hand, and the point of the spindle being pressed into the center at the end of the shaft whose revolutions are desired to be counted. Also called counter, speed-indicator, and revolution-indicator. See arithmometer.
