If the measured
Δp
reaches the design
Δp
for the selected valve, the flow status message will be FLOW OK .
However, if the design
Δp
is not met the flow status message will be LOW FLOW .
The Advanced Display can show more complex commissioning data and it may be preferred to the DP And
Flow Display if automatic balancing valves are being measured or if a system of proportional balancing is being
adopted. Fig. 3 shows an example of displayed data when a variable orifice valve has been selected and fig. 4
shows an example of displayed data when an externally adjustable automatic balancing valve has been
selected.

These are iterative processes due to the unknown valve authority in the circuit and so 2‐3 attempts may be
required to achieve the desired reading. Please also note that in conjunction with pressing the
◄
or
►
button
on the AC6 , the physical handwheel setting of the valve will also need to be changed to match the new value.
