Limiting flow
The diameter of the pipe and the flow rate determine the nominal diameter of the sensor. The optimum velocity
of flow is 6 to 10 ft/s (2 to 3 m/s). The velocity of flow (v), moreover, has to be matched to the physical prop-
erties of the medium:
• v < 6 ft/s (2 m/s): for abrasive mediums such as potter's clay, lime milk, ore slurry etc.
• v > 6 ft/s (2 m/s): for accretive mediums such as wastewater sludge, etc.
