Abstract
In a flow meter of the traveling wave type having a flexible undulating membrane, velocity detecting means is utilized to determine the velocity of propagation of the traveling wave associated with the undulating flexible membrane between at least two known locations on the flexible membrane. The velocity of propagation is proportional to the volumetric flow rate of fluid through the flow meter.
