Flow Range. These sensors are designed to operate at ow
velocities of 0.5 to 30 feet per second (see Table 2, below).
If erratic readings are encountered at low ows, check the
chart to see if ow is below minimum for the pipe size. The
standard shaft and bearings should have a long life at continu-
ous high ow.
