*The Design Flow for any automatic balancing valve will be achieved if the
Δp
across the valve reaches (or
exceeds) the design value. If the Design
Δp
is met, the displayed message will be FLOW OK . If the Design
Δp
is not met, the displayed message will be LOW FLOW .
The DP Only Display (shown in fig. 5) is the simplest option available and may be preferred when the AC6 is
being used as a simple manometer.
Fig. 5
The Flow Only Display (shown in fig. 6) would normally only be the preferred display screen when fluid
velocities are being measured for the purposes of system flushing.
