I'm a skilled fabricator but not a coder or very electronic experienced. I'm not finding anything in the market I like, plus way to $. I'm looking for someone to handle the coding and hardware spec to fill me need. I can make suggestions of what I would like to use. I will buy and assemble the hardware based on your schematic and load your code. If you can pretest what you can great. small project. Fluid flow rate and tank volume using Audrino or similar micro controller/counter to then display output on an OLED 2-3" screen For flow I will be making a small turbine using a prox to send the pulses to the "brain", from there calibration can be hard coded. Volume, I would like to use a pressure transducer at the bottom of a tank that holds 12 gal. The calibration can be done by a button to set zero point, then .25, .5, .75, 100% volume. this pressure range IE voltage will be stored to use for calcs in non volatile memory. after calibration, current Pressure will be polled every second and stored in a buffer for a minute then averaged ( a type of filtering) before displayed on a vertical color bar graph. Each column of 2 pixels wide of the then current volume will be shifted left and remain as it is replaced by the next update creating a moving trend that grows left for 30 minutes worth of moving history, 60 pixels until empty, color will change from green to yellow to red at some predetermined percentage as the graph trends down. A volume unit in gallons will also be displayed. Flow will come in a series of pulses and buffered every second. from here a stored calibration factor would be used to establish the flow rate in GPH to be displayed. Based on volume present and current flow, a "time remaining" number will be displayed and updated every 15 seconds. A complete flow and volume history will be stored from last reset button push so that this history can be averaged and compared to volume reduction history. A way of cross checking internally between flow rate and tank pressure to give average flow number, IE, flow rate gph vs tank volume reduction based on pressure transducer gph As volume decreases so will time remaining, as the volume gets down to 30% the new painted graph column, time remaining number and gallon numbers will change from green to yellow, then red at 20% of something like that. also a stored mono audio warning file at line level for output upon reaching 10% would be a nice addition. pushing the calibrate button once would defeat the audio alarm. final volume would be baked into the audio file, i think? I can provide the graphics to depict the concept further For now this is a one off project for a special application. time frame is a couple of months.

If you are willing to use Arduino like you said, we could look at some possible solutions. I just need to ask some questions.
