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