6.2 Transducer Block Parameters
The transducer block sets functions specific to
the flow rate measurement of the digitalYEWFLO.
For each block parameter in digitalYEWFLO, read
APPENDIX 1 “LIST OF PARAMETERS FOR
EACH BLOCK OF digitalYEWFLO.” The following
describes important parameters and how to set
them.
For the METHOD of TR block, read APPENDIX
10.1 “Transducer Block”.
(1) Mandatory Parameter Setting for
Transducer Block
After setting parameters of the transducer block,
set up XD_SCALE of the AI1 block (and of the
AI2 block as appropriate).
Table 6.1 shows the parameters that must be
set (in order of the relative index sequentially)
depending on the operation conditions.
