Humonic Optiflow 520 Digital Volumetric (Bubble) Flowmeter

A digital bubble flowmeter is one of the most useful tools in a GC lab. They are very reliable, and easy to use. The principle is that optical sensors detect when the bubble enters and exits the calibrated tube. A microprocessor then calculates the resulting volumetric flow rate and displays it on a small screen.
