Additonal Features


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.

Feature

Description

 

Scaling

Multiply, divide and preset values

 

 

Alarms

  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

Power up delay

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

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.

Rated 3 out of 5 by from Good box, poor manual Features as advertised, just hard to find in the text. If the manual were laid out with the clarity of older Omega products, it would have received more stars.

Rated 4 out of 5 by from DPT20 transmitter with FPR304 meter. A compact indicator/transmitter. Easy to set up. I used it with an omega FPR304 meter. Would have liked to see specific configuration in the manual for Omega products. Missed ensuring the pull up resistor setting was set ON. Simple to fix. Would have liked to be able to enter a setpoint rather than use an alarm point. Probably a feature for a different transmitter but immediate need dictated selection.

Rated 5 out of 5 by from Rate/Speed Meter Easy to use, install and configure. Used with open collector output encoder to determine speed of a linear moving device. Worked better than expected.

I have a DPF20-LV, I was testing the functions and added a password. Now 3 months later I do not recall what that password was, How to I break the pass to get into the unit to see the setting and scaling I used or worst case how do i reset the whole unit.

Could a DPF20-HV-AO display be setup with an FTB-1400 series flow meter to measure flow rates? The flow meter has a magnetic pickup sensor producing a 30 mV/P-P signal.

Asked by: AdamB_666
Yes. The FTB-1400 series is compatible with rate/totalizer display DFP20-HV-AO

I have am Omega DPF20, using Conf.6 ratemeter function. When attempting to choose Sensor option, it will not save. I try to select PnP3 however it always resets after I press the LE key. The 3 horizontal bars do flash to indicate the saving.

Asked by: tayls9
Thank you for your inquiry about the meter. Once you select the configuration input, it will save and if you let it time out, it will also save. If still having an issue, please forward to our Flow, Level, and Environmental Group at flow@omega.com

I need to limit the maximum speed of a high speed 3-phase alternator by connecting it to a braking resistor bank via relay. How quickly does this device activate one of the solid state outputs (T1 or SSR) after the signal frequency reaches the trip value?

Asked by: dgoodell
Thank you for your inquiry about the DPF20 meter. Please email flow@omega.com and can provide the response in detail per your request.

I am using this with the encoder and wheel to measure length. It works to trigger an alarm output when a particular length has been reached. Is there a setting or way to also counter or keep track of the number of times an alarm has been triggered?

Asked by: Gk22
Thank you for your inquiry. It would be best to contact us at flow@omega.com and we'll be able to help you with using this meter for your application.
