ABSTRACT:
A flow meter of the pitot type. The meter incorporates a series of apertures along a probe body for exposure to a fluid stream. The result is a number of datum which are averaged and correlated to be representative of the flow within a conduit. Aberrations encountered in noncircular ducting or other irregularities are compensated by correction. The disclosure further sets forth the use of an apparatus to effect the measurements.
