Can be used as a flow meter
I have a fill rite 820, very happy with the performance. I require a rate meter not the just the totalizer. Can this meter show the flow rate. If so how do I change it to do that.
Thank you

Brian,
thank you for your question on the 820 digital meter.This meter does not have the functionality that you are looking for. Our 825P meter which has a pulse output and a 4 - 2 mA output, does give you the ability to see the flow rate. This meter runs on the lithium cell batteries, or will take a 12 VDC input. You don't need to use the output features, yet to conserve battery life, I would supply a 12 VDC input.

This meter can be used with motor oil, as long as:
1. You can maintain a flow rate between 2 and 20 GPM.
2. You do not exceed the pressure rating of the meter; 120 psi max at 70° F / 50 psi max at 130° F.
3. The oil is clean oil. Do not use the meter for used motor oil.Let us know if you have any further questions in regards to the 820 Digital Meter.
