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 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.
The optional analog output is proportional to rate or total on the DPF75.
To amplify low-level turbine
and paddlewheel flow sensor inputs, order amplifier model number FLSC-AMP.
The DPF70 Series is the ideal solution for many flow meter applications. Omega offers many different
types of flowmeters: paddlewheels, turbines, positivie displacement, annemometers, mass flow, etc. for
many application solutions.

† All dollar amounts on this site are shown in US currency.
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 $122 to price.
For field-selectable 4-20 or 0-20 mA output, add suffix “-A” to part number, and add $115 to price (Not available on DPF76).
For direct low level signal input without external amplification, add suffix"-LL" to model number and $77 to price.
(OPTIONS SHOWN IN THIS "NOTE" ABOVE ARE PRICED IN US$)
