摘要

An ultra low pressure flow sensor consisting of a support gasket (12) defining a flow way and having a thin, pliable membrane (14) extending thereacross with right angle slits (26,28) formed totally across the flow way portion. An electrical conductor strip (16) is then bonded across each pair of opposing quadrants (32,36 and 34,38) of the membrane in continuous connection to an electrical indicator circuit. The conductor strip across each pair of membranes is centrally notched (at 54,56) to a preselected depth of cut thereby to control the flow pressure break strength.
