Nominal diameter and flow rate

The diameter of the pipe and the flow rate determine the nominal diameter of the sensor. The
optimum velocity of flow is 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 buildup such as wastewater sludge, etc.
Note!
Flow velocity can be increased, if necessary, by reducing the nominal diameter of the sensor
→ Page 19.
