*1 Rated flow range of the applicable flow switch
*2 Value without digital filter (at 0.00 s)
*3 When using the accumulated value hold function, use the operating
conditions to calculate the product life, and do not exceed it. The maximum
access limit of the memory device is 1.5 million times. If the product is
operated 24 hours per day, the product life will be as follows:
5 min interval: life is calculated as 5 min x 1.5 million = 7.5 million min = 14.3 years
•
2 min interval: life is calculated as 2 min x 1.5 million = 3 million min = 5.7 years
•
If the accumulated value external reset is repeatedly used, the product life
will be shorter than the calculated life.

*4 If the flow fluctuates around the set value, the width for setting more than
the fluctuating width needs to be set. Otherwise, chattering will occur.
*5 Setting is only possible for models with analog output.
