Flowrate Nomograph
The volume flowrate is a function of the flow velocity and the
flowmeter size. The Flowrate Nomograph shows the flow range
available for a particular flowmeter size as well as the flowmeter
sizes suitable for a particular flowrate value.
Example:
Flowrate = 7 m
3
/h (maximum value = flow range end value).
Suitable are flowmeter sizes 3/4” to 2-1/2” [DN 20 to DN 65] for
a flow velocity of 0.5 to 10 m/s.
