What are the dimensions of the FTB311 Micro-Meter

Does it display just the volume(gallon/litres) or can it display flow rate(gpm/lpm) as well?

Asked by: akasal
Thank you for your question? The FTB300 series Micro-Flow meters can display both volume and flow rate.

Is there an wiring schematic for the flow meter itself, instead of just the strainer that's in the manual? I'd like to output the signal to another unit if that's possible.
