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 between 2 and 3 m/s (6.5 to 9.8 ft/s)
The velocity of flow (v), moreover, has to be matched to the physical properties of the fluid:
• v < 2 m/s (v < 6.5 ft/s): for abrasive fluids
• v > 2 m/s (v > 6.5 ft/s): for fluids producing buildup
!
Note!
Flow velocity can be increased, if necessary, by reducing the nominal diameter of the sensor
