FLUID FLOW SENSOR HAVING MULTIPLYING EFFECT ABSTRACT OF THE DISCLOSURE: A fluid flow sensor may be installed in a duct, pipe, shaft, conduit or tube for measuring parameters of fluid flow within the duct, including especially the dynamic or velocity pressure of the flow. The sensor has two independent pressure chambers, each of which is in fluid in communication through a plurality of relatively small passages to the flow within the duct; the passages for the first chamber being directed upstream, the passages for the second chamber being directed otherwise than upstream, usually downstream. The chambers are arranged so that their axes are parallel to each other, with the axis of the first chamber upstream of the axis of the second chamber. The pressure in the first chamber is proportional to the dynamic pressure plus the static pressure, and in the second chamber to the static pressure; so that the dynamic pressure is proportional to the first chamber pressure minus the second chamber pressure. When the two chambers are independent of each other, and depending upon the profile of the sensor, the dynamic pressure and changes therein are a constant multiplier function of the first chamber pressure minus static pressure. The constant multiplier is greater than 1.0, and is constant for a given sensor across wide variation of measured pressures. When the profile of the sensor is essentially cruciform, with upwardly and downwardly extending wings, the multiplier effect may be in the order of 3.5 to 5.0, thereby permitting very low differential pressures to be detected and measured.
