10.2 Totalizer and Pulse Output
Proceed as follows to use the totalizer and pulse output.
Count Rate and Pulse Width Settings
Follow the procedure in 8.2.15 “Count Rate (Pulse Rate) and Pulse Width” and set
the flow rate per 1 count (1 pulse) (count rate), pulse width mode and pulse width.
* Count rate can be set within the range of 3.6 to 3,600,000 pulses/h (1/1000 to
1000 pulses/s) with respect to the set range. (Note 2)
* Pulse width will be set automatically if the pulse width mode is set to AUTO.
If you want to set the pulse width manually, the pulse width can be set between
0.3ms and 500ms. However, the pulse width must be 40% or less of the
full-scale period. (Note 3)
For pulse width, check the acceptable signal width of the receiving instruments
when you set the pulse width.
If the pulse output is not used, pulse width setting is not needed.
DO Setting
Follow the procedure in 8.2.14 “Digital I/O Function” and set the Digital Output 1
(DO1) or Digital Output 2 (DO2) for pulse output.
If the pulse output is not used, DO setting is not needed.
DI Setting
Follow the procedure in 8.2.14 “Digital I/O Function” and set the Digital Input
(DI) function.
In the case of the converter without Digital Input (9th digit of the product code is
“1”), set “NO USE” (factory setting).
Indicating Unit Setting
Follow the procedure in 8.2.6 “Normal Indicating Unit” and set a totalization unit
(m
3 , l, ml, gal, bbl, pt, qt or COUNT) for indicating unit.
If only the pulse output is used, pulse output can be sent out without setting an
indicating unit but it is recommended that you set a totalization unit as indicating
unit to check the operating condition.
Switching to the Measurement Mode
Follow the procedure in 7.3.1 “Mode Switching” and put the mode back to the
measurement mode.
