Hi all.
I'm trying to come up with a way to measure the very low flow rate of a gas (on the order of ml / day) without allowing backflow. Assuming this gas is under sufficient pressure to drive a metering mechanism, what would that mechanism be? As far as I've gotten: Is it possible to drive a peristaltic pump in reverse this way and count its revolutions? My intuition says no - the rotor would stall when a wheel began to engage the tube.
