Abstract
A significant problem in the flow probe art is that of accurately positioning a flow-sensing portion of the probe at a selected location within a pipe. Several arrangements are provided for determining the insertion depth of flow sensing probes, for measuring diameters of the pipes in which they are inserted, and for detecting the depth of those pipes. These generally involve adding to the flow probe a depth measurement device for generating an energetic beam that is reflected from the pipe or from an insertion fitting. One such sensor uses a phased array of piezoelectric element to serve both in a pulse-echo distance measurement device and in a time-of-flight flow measurement device.
