Apparatus and method for determining a differential pressure with respect to a remote site

Abstract

A method of measuring the differential pressure of two fluid pressure sources includes connecting a manometer having a wireless transceiver for transmitting measured pressures to a remote location and connecting a second manometer to a second pressures source. The second manometer then is operable calculate differential pressure value based upon the measured and electromagnetically transmitted fluid pressure value. If two remote manometers are used and are both transmitting their measured fluid pressure values electromagnetically, the second manometer is operable to determine a differential fluid pressure for the two fluid whose pressures were electromagnetically transmitted. An apparatus includes a manometer having a electromagnetic transceiver for transmitting and receiving fluid pressure measurements. Accordingly, the manometer is capable of determining and displaying differential pressures relative pressures it measured and to pressures it received electromagnetically that were transmitted by other manometers.
