General Mach Discussion / Re: synchronize flow rates and motor speed

yes it's possible , but you need a proportional valve to regulate the flow , on off valves etc won't do , you need to drive a pump with constant pressure and a relief valve before the proportional valve to feed back into the feed tank or a holding tank etc for when the pressure of the pump is greater than the flow rate etc , so it can just feed excess back around the system , set the relief valve just a small amount above the pressure of the flow , so it easily trips ,
