7.4 Nominal diameter and flow rate
As a rule the pipe diameter governs the nominal diameter of the sensor. When the
volume flow is known, it is possible to estimate from the table below whether the
optimal velocity range of 2...3 m/s can be adhered to.
The flow velocity (v) also has to matched to the physical properties of the medium:
•
v < 2 m/s: with abrasive media (potter’s clay, lime milk, or slurry)
•
v > 2 m/s: with media forming a coating (waste-water sludge, etc.)
If it is necessary to increase the flow velocity, this can be done by reducing the
nominal diameter of the sensor (see chapter 3.3 “Adaptors”).
The table below summarizes the minimum and maximum full-scale values (incl. works
setting) which can be set by miniature switches in Promag 30.
