Omega’s new DPF20 Series of indicators offer real flexibility for measurement of a wide range of frequency or pulse inputs. The display is easily configured to indicate frequency, rate, period or count. This makes the meter ideal for flow applications where they can display flow rate or total from a variety of different flow sensors. Or for quadrature signals, to indicate angular position or rotational speed and direction.

The DPF20 series offers exceptional performance at an economical price, with some unique and powerful features.





Multiply, divide and preset values




  1. configure a second setpoint in the same alarm, to create “alarm windows”
  2. configure independent activation and deactivation delays
  3. configure hysteresis
  4. configure alarm to activate as high or low
  5. failsafe function – normally closed relay requires activation for non-alarm condition
  6. latched alarms function – operator reset required
  7. Counter Reset, Stop or Continue
  8. Configurable hysteresis

On power Up

Allows for a delay in the start-up time after powering the instrument. During this time the instrument performs no measurement or control.
Ability to reset the display count on instrument start-up.

Display Brightness

Select from 5 levels of LED intensity.


Password protect the configuration menu.
This blocks access to the instrument set-up parameters, but the operator can still access set-point values.

Max / min memory

Front panel key selection of display minimum or maximum values

Sensor Type

The fast and simple way to configure a sensor. Select from a predefined list Eg. NPN, PNP, Namur, pick-up, inductive, etc.
The instrument will automatically configure the required parameters for the selected sensor (pull-up / pull-down resistors, trigger level, excitation voltage, etc)

Trigger sense

Simple selection of the optimal trigger level for the sensor input. The display indicates up or down reflecting the status of the input signal level. When the LED changes state continuously the optimal trigger level has been achieved.
