Preset Counters

The Smith Meter Model 300C Series Preset Counters are four-digit (340C) or five-digit (350C), two-stage, preset (down) counters designed for mounting directly under a Model 600 Series Counter on all Smith Meter PD meters. They are used with appropriate accessories to either mechanically or electrically trigger two-stage valve closure to control precise, shock-free delivery of a preset quantity of liquid. The signal to initiate first stage valve shut-down is field-adjustable from 3 to 9, 10 to 90, or 100 to 900 right-hand wheel units. The final stage shut-down signal, just prior to zero, is easily field adjusted on start-up to assure precise delivery of the preset quantity.
