Abstract A combination counter and transmitter device for use with a liquid flow meter includes a coupling for connecting the device to the flow meter for rotating a gear on the coupling in response to liquid flow through the meter. A gear train drives counter wheels to count the volume of liquid flow through the meter and interconnected with the gear train is additional gear means for driving a first shaft which may be coupled to a correction arrangement for determining a correction factor to be applied to the volume as shown by the counter wheels of the present invention. The first shaft when not attached to the correction equipment may be employed to operate a sampler in the liquid line or for transmitting pulses or for other uses. Still additional gear means associated with the gear train and interconnected with the gear means that moves the counter wheels and the first shaft means rotates a second shaft means on which are mounted cam means. A switch is pivotally mounted adjacent the cam means and the gear train ratio is such that for each revolution of said second shaft means a predetermined volume of liquid flow will pass through the meter, and as the cam means is rotated by the shaft means, the switch means is actuated to generate a pulse for transmitting to any other desired equipment as an indication of a predetermined flow of liquid through the meter.
A transmitter and counter device for use with a liquid flow meter to transmit and count the volume of liquid flow through the meter comprising: a. rotatable coupling means for connecting the device with a liquid flow meter for rotation by the meter; b. drive gear means connected to said coupling means and rotatable thEreby in response to liquid flow through the meter; c. gear train means engaged with said drive gear means and rotatable thereby; d. additional gear means engaged with said gear train; e. first shaft means connected with said additional gear means and rotatable upon rotation of said additional gear means; f. second additional gear means engaged with said gear train; g. a plurality of counter wheels engaged with said second additional gear means; h. support means supporting said counter wheels for rotation by said second additional gear means; to count the volume of liquid flow through the meter; i. third additional gear means engaged with said second additional gear means and rotatable thereby; j. second shaft means engaged with said third additional gear means and rotatable thereby; k. cam means mounted on said second shaft means and rotatable therewith; and l. switch means pivotally supported adjacent said cam means and engagable by said cam means upon rotation of said second shaft means and cam means for transmitting an electrical pulse each time said cam means contacts said switch means in response to a predetermined volume of liquid flow through the meter.
