Which is why it might be a good idea to build your chamber out of a large diameter piece of pipe with reducing fittings at each end, Terry. The larger diameter will slow the flow rate in that section without changing the overall fill time of the tank by much, if any.

If that's the case, Terry, you may have the perfect piece of equipment. Set it up like this: Set the current control to full scale and the voltage to zero. Turn on the power. Start the water flowing through the chamber. Gradually increase the voltage and watch the current rise in response. Once the current exceeds the amount we calculated (6A for 10 ppm in 160 gallons in 15 minutes) by maybe a few amps, start turning the current control *down* until it starts to regulate the current by reducing the voltage being supplied to the cell. Adjust the current to your desired setpoint. Now it's in current limiting mode and will continue to adjust the voltage up or down in response to changing conditions, so long as the voltage needed is no more than you have the voltage control set for. As long as you keep it in current control mode, you will have a very accurate measure of the weight of silver you're putting into the water in any given period of time. It should even be relatively independent of water quality, temperature, and moderate changes in flow rate. Does that start to make sense? I think you've got the makings of a very nicely controlled system. Be well, Mike D.
