4.7. Switching measurement mode
4.7.1. Setting measurement mode and CH3 (calculation output)
Description
 Measurement mode can be selected.
 When 2-pipe measurement is selected, the calculation formula for CH3 can be configured.
Settable range
1. Measurement mode : 1-path, 2-path, 2-pipe
・
1 PATH : Measure flow rate and thermal energy in 1 pipe using 1 set of detector
・ 2 PATHS : Measure flow rate in 1 pipe using 2 sets of detector
・
2 PIPES : Measure flow rates in 2 separate pipes using 1 set of detector for each pipe.
2. CH3 calculation output : average, addition, subtraction (CH1-CH2), subtraction (CH2-CH1)
When selecting 2-pipe measurement mode:
・
AVERAGE
＝
(path 1 + path 2
）
/ 2
・ ADDITION ＝ path 1 + path 2
・
SUB (CH1-CH2)
＝
path 1 - path 2
・
SUB (CH2-CH1)
＝
path 2 - path 1
* When selecting 2-path measurement mode, average value is output for CH3.
* When selecting 1-path or 2-path measurement mode, there is no setting items of CH3.
For actual keying, refer to the typical operation indicated below. Set the protection to OFF beforehand. (See Section 4.5.1.)
Operation
(example) Set measurement mode to 2-pipe and CH3 calculation output to subtraction (CH1-CH2).
