Abstract
An inflatable air cell pressure transducer. The air cell has a concavity formed therein. The concavity has two edges, wherein increased pressure within the air cell causes contraction of the concavity moving the two edges closer.
Claims4
An inflatable manometer comprising:
- an air cell having a concavity formed therein, said concavity having two edges, wherein increased pressure within said air cell causes contraction of said concavity moving said two edges towards each other;
- a second concavity formed in said air cell, said concavity having a first characteristic such that said concavity closes at a first pressure, said second concavity having a second characteristic such that said second concavity closes at a second pressure, said second pressure being greater than said first pressure.
An inflatable manometer comprising:
- an air cell having a concavity formed therein, said concavity having two edges, wherein increased pressure within said air cell causes contraction of said concavity moving said two edges towards each other;
- a fluid inlet and a fluid outlet coupled to said air cell, said manometer indicating a pressure differential between said fluid inlet and said fluid outlet.
