I am looking for a product that an operator can set or select a number of gallons of water. Then activate to have that number of gallons flow to fill a tank. I all ready have a 12 volt pulse flow meter. It needs to operator friendly.
It seems OP wants to automate the process such that when the calculated flow reaches a setpoint equal to the tank volume a signal is sent somewhere to close something (perhaps a valve).
Perhaps we will learn more in the next iteration should there be one. I too am trying to imagine what the goal here is.
Simplest for me would be figuring out (if water pressure remained constant) number of gallons per minute through my fill pipe, which could be controlled with a gate or ball valve so it was a usable number.
Example: I closed the valve until the pipe was flowing 1 gallon a minute. I would put a solenoid in the line closer to my tank and hook a digital timer switch to it. Run the timer wires to the solenoid and you are in business.
I want 1 gallon in the tank, set the timer for 1 minute. 3 1/2 gallons, set for 3 1/2 minutes.
Depends how much flow I could get. If 6 gallons a minute, then setting the timer for 10 seconds would give me a gallon.
Pretty simple to do, and not too expensive. Ball valve, solenoid and digital timer switch.
Just make sure no one messes with your ball valve (which controls the GPM of water).
Keep it super simple, check to see if the flow meter has an out put of some type or set point. There is a difference in a controller and a meter. Perhaps the meter could drive a controller. If not back to drawing board. Try www.omega.com they have it all, from lab size to batch size.

What I have installed as of now is a flow meter that is calibrated as 339 pulses per gallon of water with a 12 volt supply. I am looking for a controller to send these pulses to and open and then close a solenoid valve when the process starts and then when it reaches set point. The objective is for an operator to enter a number and for the system to dump that number of gallons into a tank. I cannot rely on system water pressure to remain constant. I will look at Omega as suggested.
