1: The air quality class is according to JIS B 8392-1:2012 [4:6:-] and ISO8573-1:2010 [4:6:-].
2: The set range changes based on the setting of the zero cut-off function.
3: When using the accumulated value hold function, calculate the product life from the operating conditions, and use the product within
its life. The maximum update limit of the memory device 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.
4: When pipe bore sizes 3/8 (PF3A701H) and 1/2 (PF3A702H) are connected.
5: In the low flow rate range, the temperature value fluctuates (rises). Refer to the temperature accuracy chart. (Page 100)
6: 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.
7: These values are for modular products with a pipe bore size of 3/8 (PF3A701H), 1/2 (PF3A702H), and supply pressure of 0. 5 MPa.
8: The time can be set from when the instantaneous flow reaches the set value, to when the switch output actually begins working.
9: 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.
10: The flow rate given in the specification is the value at standard condition (STD).
11: This is only available for models with the units selection function.
12: Displayable range change based on the setting of zero cut-off function.
13: 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.
14: Anyｓ products with tiny scratches, smears, or display colour variation or brightness which does not affect the performance are
verified as conforming products.
