Example 1
Given : Design flow to zone
4200 l/h, pressure drop over
the zone at design flow 25 kPa.
Solution: AB-PM DN 40 is
selected. Δp setting is kept
at factory setting and flow
limitation is changed to 80 %.
AB-PM will control differential
pressure of 25 kPa when
design flow is achieved and
the flow to the zone will be
limited to 4200 l/h
