Claim 1
Independent Claim
187 words
A DEVICE FOR MEASURING THE VELOCITY OF A FLUID STREAM COMPRISING: (A) A POWER NOZZLE, (B) MEANS FOR CONNECTING SAID NOZZLE TO A PRESSURE SOURCE OF SAID FLUID TO CAUSE TO ISSUE FROM SAID NOZZLE A JET OF FLUID HAVING AN APPROXIMATELY GAUSSIAN PRESSURE DISTRIBUTION IN A PLANE TRANSVERSE TO THE AXIS OF SAID JET, (C) RECEIVER MEANS INCLUDING FIRST AND SECOND RECEIVER MOUTHS, (D) MEANS MOUNTING SAID RECEIVER MEANS TO SPACE SAID RECEIVER MOUTHS FROM SAID NOZZLE SUBSTANTIALLY IN THE DIRECTION OF FLOW OF SAID JET, WITH EACH MOUTH ORIENTED TO RECEIVE FLUID FROM SAID JET, (E) MEANS FOR LOCATING SAID NOZZLE AND SAID RECEIVER MOUTHS IN SAID FLUID STREAM WITH SAID JET EXTENDING DIRECTLY ACROSS THE STREAM DIRECTION, (F) SAID MEANS (E) INCLUDING MEANS FOR LOCATING SAID FIRST RECEIVER MOUTH AT A FIRST DISTANCE UPSTREAM OF SAID NOZZLE IN SAID STREAM DIRECTION AND MEANS FOR LOCATING SAID SECOND RECEIVER MOUTH DOWNSTREAM OF SAID NOZZLE IN SAID STREAM DIRECTION AT A SECOND DISTANCE GREATER THAN SAID FIRST DISTANCE, (F) AND MEANS CONNECTED TO SAID RECEIVER MEANS FOR MEASURING THE DIFFERENTIAL FLUID PRESSURE BETWEEN SAID RECEIVER MOUTHS.
