Measuring range
The measuring range is dependent on the nominal diameter, the fluid and environmental influences.
The following specified values are the largest possible flow measuring ranges (Qmin to Qmax)
for each nominal diameter. Depending on the fluid properties and environmental influences,
the measuring range may be subject to additional restrictions. Additional restrictions apply
to both the lower range value and the upper range value.
