ABSTRACT:
A device for recording the flow rate through a flow meter over a period of time is provided for use in conjunction with a flow meter having a rotatable member, the rotational position of which is indicative of the fluid flow rate through the flow meter. The recording device comprises a housing in which a recording medium is mounted and rotatably driven at a predetermined. rate. An elongated scribe arm is pivotally secured at one end to the housing and, at its other end, has a writing instrument which engages the writing medium and produces a visible mark thereon. Similarly, an elongated actuating arm has an axle which is pivotally mounted to the housing and this axle in turn is connected to the flow meter rotatable member. The actuating arm and scribe arm are in turn connected together by a connecting arm which is pivotally connected to the actuating arm at one end and pivotally connected to the scribe arm at its other end. Moreover, the pivotal connection between the connecting arm and both the scribe arm and the actuating arm are radially spaced from their respective pivotal mounting points so that pivotal movement of the actuating arm causes a like and proportional pivotal action of the scribe arm.
