Pressure management arrangement
First Claim
1. A pressure measurement arrangement for measuring a line pressure of a product, comprising:
- a reusable pressure sensor comprising a measurement diaphragm; and
a fitting, said fitting comprising;
a tubular opening extending through said fitting, for the reception of a disposable elastomeric tube, an aperture extending through an outside wall of said fitting into said tubular opening; and
mounting means, for mounting said reusable pressure sensor on saidaperture, such that said measurement diaphragm is exposed to an inside of said tubular opening;
wherein;
said disposable elastomeric tube is inserted in said tubular opening of said fitting during measurement; and
an outside wall of said disposable tube comprises a thin flexible portion, which conforms to said measurement diaphragm when said disposable elastomeric tube is pressurized by the line pressure.
