Nominal diameter and flow rate

The pipe diameter and the flow rate determine the nominal diameter of the sensor. Optimum flow
velocity is between 2 and 3 m/s. The flow velocity (v) must also match 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 that tend to cause buildup, such as wastewater sludge etc.
Note!
If the flow velocity has to be increased, this can be achieved by reducing the nominal diameter of
sensor (→ ä 17).
