The fluid flow meter (10) includes a flexible membrane (35) formed of a flexible material and containing an apparatus for providing the membrane (35) with resilience for undulation. The membrane (35) is mounted in the fluid flow path such that the pair of faces simultaneously define with the housing fluid impermeable seals (67) at the least two different locations along the flow path. The membrane (35) flexes so as to permit passage of discrete quanta (62a) of fluid, each having a known volume. The flow meter (10) generates electrical signals corresponding to flexure of the membrane (35), and the electrical signals are monitored for determining a fluid flow rate. |
