Azbil MQV9020 - Flow Rate Range

5-18
Chapter 5. ADVANCED OPERATION
5-4 Flow Rate Range
The flow rate range can be reduced to a level of 99% down to 10% of the standard range using
the flow rate range setup (
C-24
or
C-25
). However, the minimum control flow rate is the same
as for the standard range. As the range is reduced, the setup and display resolution levels are im-
proved as described in the table below.

Handling Precautions
•
Even after flow rate range is changed, the accuracy specifications
are the same as for the standard range. (The full scale designated
by % FS shows the numeric value of the standard range.)
•
Even though the flow rate range is changed, the minimum control
flow rate is the same as for the standard range.
•
Analog input/output scaling is changed automatically so that the
flow rate range after the change is shown as full scale (FS).
