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 |
|
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. |
Display Brightness | Select from 5 levels of LED intensity. |
Password | Password protect the configuration menu. |
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. |
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. |

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.

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.

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.

Could this device measure the frequency/RPM of one of the phases of a 3-phase alternator that operates at 0-3000 Hz, as long the voltage was kept within 30V p-p?
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 looking to verify that a panel meter such as the Item# DPF20-HV-R1-AO could be used to read/calibrate the output of a rotary encoder such as an AU-ZBG model.
Thank you for contacting Omega Engineering. Concerning your inquiry, yes the DPF20-HV-R1-AO is compatible with rotary encoders such as an AU-ZBG. It will convert the pulses from the encoder to a speed value, that will be displayed on the screen.

How is the rear reset terminal configured? Was looking to put a simple pushbutton for this operation, but there are no spec on voltages, wiring etc.
Thank you for your inquiry about the meter. If you want to use a push-button to reset the display value, you must connect it between pin 5 (reset) and pin 1 (0V).
When the contact closed, it apply the reset on the display.--> This is the “Reset default configuration” and is the solution most used.

Would a DPF20-HV-AO-T1-NBT allow me to process a pulse signal to provide a 4-20mA proportional to the flowrate (0 to 33.1kHz) and a pulse signal for every 0.1 gallons (1 per 26,500 pulses) that went by?
Thank you for your inquiry about the display meter. Please forward that request to our Flow Department where we can have our Design Engineer review and advise per your request and the email is flow@omega.com

Are there MODBUS and Serial Communication manuals for DPF20 displays? If so where can I locate them?
Thank you for your inquiry about the meter. Yes, the information is available in the manual on page 27.
