Supported Applications
The Omega DPF700 series is a programmable digital meter designed as a Ratemeter/Totalizer/Controller. It measures rate from 0.5 Hz to 30 kHz and totalizes up or down from -99,999 to 999,999 or acts as an accumulating stopwatch. The device supports line frequency measurement and Revolutions per Minute (RPM) measurement examples.
Operating Conditions & Performance
The DPF700 features a 6-digit, 7-segment red LED display with 14.2 mm H height. Accuracy is specified as ±0.5 LSD of total and 0.01% of the rate ±1.5 LSD. The gate time for rate measurement is 0.30 sec using a 1/x technique.
Input characteristics include:
- Type: Single input compatible with TTL, CMOS, NPN open collector, contact closure, and magnetic pickup (selected by DIP switch; non-isolated).
- Level: Maximum 60V; minimum 25 mV rms.
- Frequency: 30 kHz maximum.
- Excitation: Regulated at 5.0, 8.2, or 12.4V selected by DIP switch (100 mA maximum).
The meter operates on a power supply of 115 Vac/7.5 to 13 Vdc powered (DPF701) or 230 Vac/7.5 to 13 Vdc powered (DPF702). Physical dimensions are 48 H x 96 W x 152 mm D (1.9 x 3.8 x 6") with a weight of 454 g (1 lb).
Configuration Options
The series offers configurable options for output, control, and mounting:
- Power Supply Models: DPF701 (115 Vac/7.5 to 13 Vdc) or DPF702 (230 Vac/7.5 to 13 Vdc).
- Option Boards (Field Installable):
- Analog output board: DPF700-A3.
- Dual 5A relay board: DPF700-R.
- RS232 output board: DPF700-232.
- Accessories:
- 1/8 DIN bumper band (DP40-BB-(*)).
- 1/8 DIN panel punch (DPP-5).
The analog output is scalable to 4 to 20 mA, 0 to 20 mA, or 0 to 10 V. The dual relay option provides two Form C relays rated at 5A. RS232 communication and setpoints are available as optional features.
Key Product Differences
The primary distinction between models is the power supply voltage: DPF701 supports 115 Vac/7.5 to 13 Vdc, while DPF702 supports 230 Vac/7.5 to 13 Vdc. Both share identical measurement ranges and display specifications.
Optional boards modify the meter's functionality:
- The DPF700-A3 adds analog output capability (4–20 mA, 0–20 mA, or 0–10 V).
- The DPF700-R provides dual 5A Form C relay outputs.
- The DPF700-232 enables RS232 communication output.
Mounting accessories include the DP40-BB-(*) bumper band, available in colors specified by code: GY (gray), YL (yellow), BK (black), BL (blue), GR (green), RD (red), OR (orange), VL (purple), or WH (white). The standard panel cutout is 45 H x 92 mm D (1.8 x 3.6").

Easy to set up for rate measurement
I'm using this with a turbine flow sensor (model FTB602B) and with the friendly assistance of the Omega tech support, it was easy to get the two working together.

i have a dpf700 meter with a turbine fan flange pickup that has a K factor of 5.64. what setting should i set on my dpf700 meter?
Thank you for your inquiry! If you are looking to track the flow rate then you will have to go to the scale portion of the menu and enter the scale factor based on the units of measure. The scale factor and further programming information can be found on page 20 of the manual.
