Dan, thanks for getting back.. This is a completely manual system. Empty bags; they could be anywhere from 1 gallon to 3 gallons they way I understand it (we don't have any yet to look at or practice with..). The filler neck is only about an inch long from the filler valve seat. Since we are cueing off of the weight of the bag, the time issue is moot. The empty bag is manually connected to the filler, the empty bag is laid onto the scale, the start button is pressed, the valve opens, when the weight reaches the setpoint (handled by the scale controller), the signal is sent to close the valve. The full bag is manually unloaded, capped and placed to the side. Tare is handled through the scale's controller. This is going to be used in a beverage concentrate line, so 5% or less error is probably going to be OK.. The % error on our 3.5 gallon bucket fill line is close to that much.
