Pressure measuring apparatus
First Claim
1. AN APPARATUS TO ACCURATELY MEASURE THE MAGNITUDE OF THE PRESSURE OF A FLUID FLOWING THROUGH A FLOW PIPE, COMPRISING A RIGID PIPE SECTION ADAPTED TO BE INSERTED AS A PART OF SAID FLOW PIPE, SAID PIPE SECTION HAVING A THIN ELONGATED FLEXIBLE TUBE OF THE SAME LENGTH AS SAID RIGID PIPE SECTION POSITIONED WITHIN SAID RIGID PIPE SECTION, SAID TUBE BEING OF A SLIGHTLY SMALLER OUTSIDE DIAMETER THAN AN INSIDE DIAMETER OF SAID PIPE SECTION, SAID FLEXIBLE TUBE HAVING ITS OUTER END PORTIONS FIXEDLY CONNECTED TO THE INNER CIRCUMFERENTIAL END PORTIONS OF SAID PIPE SECTION TO FORM A FLEXIBLE SEAL BETWEEN THE FLOWING FLUID AND SAID RIGID PIPE SECTION, A PORTION OF SAID FLEXIBLE TUBE POSITIONED BETWEEN THE END PORTIONS OF SAID TUBE HAVING A PLURALITY OF ELONGATED CORRUGATIONS THEREIN AND SAID FLEXIBLE CORRUGATED PORTION OF SAID TUBE AND THE SURROUNDING INNER WALL OF SAID PIPE SECTION ADJACENT THERETO PROVIDING A LIQUID-FILLED PRESSURE SEAL THROUGH WHICH THE MAGNITUDE OF THE PRESSURE OF THE FLUID FLOWING THROUGH SAID FLOW PIPE IS TRANSMITTED TO A PRESSURE ACTUATED RECEIVING INSTRUMENT.
