The DPF75 is a combination 6-digit totalizer/batch controller and 5 1 /2 -digit ratemeter with two relays for 2-stage batch control or dual rate alarms. One relay can be set for batch and the other set for rate alarm, if desired. The totalizer and ratemeter display in the same engineering units, the ratemeter displaying in units per second, minute, or hour. The DPF75 can accept two inputs and separately scale them for “A-B” or “A+B” with display and relay control of the net total in engineering units. Either input A rate or net total can be displayed. The DPF76 is a 6-digit scalable totalizer/batch controller ONLY with two relays for 2-stage batch control. The DPF78 is a 4 1 /2 -digit scalable ratemeter ONLY with two alarm relays. New options now available include a 4-20 or 0-20 mA (field selectable) analog output for the DPF75 or DPF78. On the DPF75, the analog output is field selectable to be proportional to rate or total. The analog output can be powered from the DPF70’s dc power output. In addition, all DPF70 units can directly accept low level turbine or paddlewheel sensor inputs when they are ordered with the “-LL” option.

Note: For 220 Vac power, add suffix “-220 Vac” to part number No charge. For RS-232 or RS-422 output, add suffix “-RS232” or “RS-422” and add $128 to price. Example: DPF75-RS232 is a ratemeter/batch controller with RS-232 output. Price: $406. For field-selectable 4-20 or 0-20 mA output, add suffix “-A” to part number, and add $131 to price. -A option is not available on models with RS232 or RS422 option.
