Patent abstract
A precision gas flow meter that is capable of measuring small flow rates of gasses precisely in the range of 0.01 to 10 L per minute. The meter is designed to measure the gas flow in small volume increments of predetermined value, and therefore can be used to measure a gas flow that is continuous or discontinuous. The flow meter can be used to measure the gas production rates from many processes, including biological reactors, chemical reactors, and thermal-chemical reactors. The device can also be used to meter the gases that are required in small or minute volumes.
