3.2.7 Nominal diameter and flow rate
The diameter of the pipe and the flow rate determine the nominal diameter of the sensor.
The optimum flow velocity is between 2...3 m/s. The velocity of flow (v), moreover, has
to be matched to the physical properties of the fluid:
•
v < 2 m/s: for abrasive fluids such as potter's clay, lime milk, ore slurry, etc.
•
v > 2 m/s: for fluids producing build-up such as wastewater sludge, etc.
!
Note!
Flow velocity can be increased, if necessary, by reducing the nominal diameter of the
sensor (see Section 3.2.6).
