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