1: The air quality class is according to JIS B 8392-1:2012 [3:6:-] and ISO8573-1:2010 [3:6:-].
2: When using the accumulated value hold function, calculate the product life from the operating conditions, and use the product within
its life. Maximum updating time of accumulated value is 1.5 million times.
If the product is energized for 24 hours per day, the product life will be as follows:
•Data memorized every 5 minutes --- 5 minutes x 1.5 million times = 7.5 million minutes = 14.3 years
•Data memorized every 2 minutes --- 2 minutes x 1.5 million times = 3 million minutes = 5.7 years
If the Accumulated Flow External Reset is repeatedly used, the product life will be shorter than calculated life.
3: When the pressure range is 1.0 to 1.5 MPa. The pressure characteristics will be ±5%F.S. to the standard pressure of 0.5 MPa.
Do not release the OUT side piping port of the product directly to the atmosphere without connecting piping. If the product is used with
the piping port released to atmosphere, accuracy may vary.
4: The time can be set from when the instantaneous flow reaches the set value, to when the switch output actually begins working.
5: If the applied voltage fluctuates around the set value, the width for setting more than the fluctuating width needs to be set. Otherwise,
chattering will occur.
6: Analogue output or external input can be selected by pressing the buttons. Refer to the graph for analogue output.
7: When selecting 0 to 10V, refer to the analogue output graph for the allowable load current.
8: The time from when the flow is changed as a step input (when the flow rate changes from 0 to the maximum flow instantaneously)
until the analogue output reaches 90% of the rated flow rate.
9: Analogue output or external input can be selected by pressing the buttons.
10: The flow rate given in the specification is the value at standard condition (STD).
11: Setting is only possible for models with the unit selection function.
12: Displayable range change based on the setting of zero cut-off function.
13: Upper 6 digits are displayed and ×10
14: Set the time for digital filter to the sensor input. The response time indicates when the set value is 90% in relation to the step input.
15: Any products with tiny scratches, smears, or display colour variation or brightness which does not affect the performance are verified
as conforming products.
