Claim 1
Independent Claim
178 words
A FLOWMETER FOR MEASURING THE RATE OF FLUID FLOW IN A CONDUIT, THE FLOWMETER COMPRISING: A TRANSMITTING TRANSDUCER MOUNTED ON A SIDE OF SAID CONDUIT FOR DIRECTING A CONVERGENTLY FOCUSED ULTRASONIC BEAM ACROSS THE FLUID FLOWING IN SAID CONDUIT, AT LEAST ONE RECEIVING TRANSDUCER MOUNTED ON A SIDE OF THE CONDUIT TO RECEIVE THE TRANSMITTED BEAM TRAVERSING THE FLUID FLOWING IN THE CONDUIT, ONLY A RELATIVELY SMALL PORTION OF THE RECEIVING TRANSDUCER MEASURED PARALLEL TO THE DIRECTION OF FLUID FLOW INTERCEPTING THE FOCUSED BEAM, WHEREIN DISTINCTLY DIFFERENT PORTIONS OF THE TRANSDUCER ARE STRUCK BY THE BEAM AS THE BEAM IS DEFLECTED TO DIFFERENT DEGREES BY THE VARYING RATES OF FLOW OF THE FLUID, BEAM STRENGTH VARYING MEANS INTERPOSED BETWEEN THE ONCOMING BEAM AND THE RECEIVING TRANSDUCER MEANS FOR VARYING THE STRENGTH OF THE BEAM IMPINGING ON THE RECEIVING TRANSDUCER WITH THE DEGREE OF DEFLECTION OF THE BEAM IN THE DIRECTION OF FLUID FLOW, AND MEANS RESPONSIVE TO THE VARYING OUTPUT OF SAID RECEIVING TRANSDUCER FOR INDICATING THE DEGREE OF BEAM DEFLECTION AND HENCE THE RATE OF FLUID FLOW.
