During the fermentation of North Sea Gas to single cell protein in a gas‐recycle system (Spivey 1973) there was a need to measure continuously low gas flow rates and to obtain a recorder signal proportional to the instantaneous flow rate. Commercial equipment, such as differential pressure transmitters linked to a pneumatic recorder, was expensive and not readily modified for the low flow rates of laboratory fermentations.
