5. EXPLANATION OF BASIC ITEMS
5.3 Transducer Block Parameters
The transducer block sets functions specific to the flow
rate measurement of the ADMAG AXF. Figure5.3.1
presents the diagram of the Transducer block.
PRIMARY_VALUE_RANGE:
Shows the range of PRIMARY_VALUE. The engi-
neering units must match the units selected in the
parameter XD_SCALE of the AI Block that reads the
channel with this value.
PRIMARY_VALUE_FTIME:
Sets the time constant of damping to the flow rate
calculation.
PRIMARY_VALUE_LOWCUT:
Sets low cut range for output. Setting range is 0 to
10% of PRIMARY_VALUE_RANGE. EU_100.
"0%" is factory set.
Normally low cut be set by this parameter, not by
LOW_CUT of AI function block.

Diagram of the Transducer Block
For a list of the parameters of each block of the
ADMAG AXF, refer to "List of parameters for each
block of the ADMAG AXF" in Chapter 8. The
following is a list of important parameters.
NOMINAL_SIZE:
Sets the size of the flowtube.
NOMINAL_SIZE_UNIT:
Sets the unit of the flowtube size.
LOW_MF:
Sets the meter factor of low frequency side for stan-
dard dual frequency excitation.
HIGH_MF:
Sets the meter factor of high frequency side for
standard dual frequency excitation.
LOW_MF(EDF):
Sets the meter factor of low frequency side for en-
hanced dual frequency excitation.
HIGH_MF(EDF):
Sets the meter factor of high frequency side under
enhanced dual frequency excitation.
