The Flo-tech F6600 series rate/counter digital display with integrated signal processor accepts the frequency signal from Flo-tech's Ultima and Classic Turbine Flow Sensors as well as inputs from a variety of sources including switch contacts, outputs from CMOS or TTL circuits, and magnetic pickups. These meters provide six different display indications, including: counter A, counter B, counter C (slave display), rate, rate maximum and rate minimum. Annunciators indicate which display is being shown.

Similar to the F6700/F6750 series, these units can be customized to meet individual specifications through the addition of three types of optional plug-in cards: analog outputs, communications, and setpoint alarms. The analog output and communication cards can be installed by the factory at the time of order, or they may be installed by the customer at a later date. The setpoint alarm cards are available for customer installation and setup only.

Applications include: Remote flow meter monitoring, rate comparisons, alarm processing, process control.
