Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
173 words
A DOUBLE INTEGRATION FLOW METER FOR MEASURING THE VOLUME OF A FLOWING FLUID WHEREIN THE FLOW RATE IS PROPORTIONAL TO THE SQUARE ROOT OF THE FLOW PRESSURE OF THE FLUID, THE DIFFERENTIAL PRESSURE DROP ACROSS AN ORIFICE AND INVERSELY PROPORTIONAL TO THE SQUARE ROOT OF THE TEMPERATURE OF THE FLUID COMPRISING, (A) A DIFFERENTIAL PRESSURE TRANSDUCER, (B) A PRESSURE DROP TRANSDUCER, (C) A TEMPERATURE TRANSDUCER, (D) A FIRST INTEGRATOR FOR RECEIVING MEASUREMENTS FROM ALL OF SAID TRANSDUCERS, (E) A SECOND INTEGRATOR CONNECTED TO THE OUTPUT OF THE FIRST INTEGRATOR AND INTEGRATING SAID OUTPUT, (F) A SIGNAL LEVEL DETECTOR AND TRIGGER CIRCUIT CONNECTED TO THE OUTPUT OF THE SECOND INTEGRATOR, (G) A RESETTING CIRCUIT CONNECTED TO SAID DETECTOR AND TRIGGER CIRCUIT AND TO SAID FIRST AND SECOND INTEGRATORS, (H) SAID DETECTOR AND TRIGGER CIRCUIT BEING ACTUATED ON A PREDETERMINED OUTPUT OF THE SECOND INTEGRATOR THEREBY ACTUATING SAID RESETTING CIRCUIT AND RESETTING THE INTEGRATORS, AND (I) A COUNTER CONNECTED TO THE DETECTOR AND TRIGGER CIRCUIT AND ACTUATED BY SAID CIRCUIT TO MEASURE TOTAL VOLUME FLOW.
