OMEGA Engineering, Inc. Dual Ratemeter / Totalizer DPF80

The DPF80 series (Dual Rate Totalizer) is a 5 digit Ratemeter, 6 digit Totalizer in a 1 /8 DIN package. The DPF80 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. User selects 1 of 6 displays to show A, B or C rate and A, B or C total. Inputs A and B have separate scaling to read in engineering units. A 4-20mA (0-20mA) output of the C rate or total is optional. The user can press the VIEW button to see 6 separate items, total A, total B, total C, rate A, rate B, rate C. Negative values are displayed with a negative symbol (-12345). For the C value, the user can choose from the following combination of A&B inputs: TOTAL; with a choice of A+B or A-B, RATIO; with choice of A ÷ B (x100) to show percent of A to B quantity or A ÷ [A + B (x100)] to show percent of A to total quantity. Two independent presets are standard. User selects whether output A is activated by total or rate value of input B or selected C. Outputs activated by A or B total can be set to latch or auto recycle with an adjustable output duration from 00.1 to 99.9 sec. For rate, ratio, or C total, outputs pull in when value (equal or above the preset and drop out when value) is below the preset minus the selected 0 to 99.9 hysteresis.
