flow Range. These sensors are designed to operate at
flow velocities of 0.2 to 30 feet per second (see Table 4,
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 continuous high flow.
