Bypass structure with protruding part
at the main piping, reduces the
contact of moist air with the sensor,
reducing degradation of the sensor
and maintaining accuracy.
Functions

Response time can be set depending on application.
 The accumulated indication shows the operating
flow rate or residual amount (of N2, etc.)
in a gas cylinder.

pneumatic circuit
Select a digital flow switch to increase energy savings!
Flow control is necessary for promoting energy saving in any application.
Saving energy starts from numerical control of the flow consumption of equipment and lines and
clarification of the purpose and effect.
Digital display allows visualization.

∗1
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
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 million = 5 million min = 9.5 years
•
2 min interval: life is calculated as 2 min x 1 million = 2 million min = 3.8 years
If the accumulated value external reset is repeatedly used, the product life
will be shorter than the calculated life.
∗2
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.
∗3
The time from when the flow is changed by a step input (when the flow rate
changes from 0 to the maximum value of the rated flow range instantaneously) until
the switch output turns ON (or OFF) when set to be 90 % of the rated flow rate
∗4
If the flow fluctuates around the set value, be sure to keep a sufficient margin.
Otherwise, chattering will occur.
∗5 Setting is only possible for models with analogue output.
∗6 The time from when the flow is changed by a step input (when the flow rate
changes from 0 to the maximum value of the rated flow range instantane-
ously) until the analogue output reaches 90 % of the rated flow rate
∗7 Setting is only possible for models with external input.
∗8
The flow rate given in the specifications is the value under standard conditions.
∗9 Setting is only possible for models with the units selection function.
∗10 The accumulated flow display is the upper 3-digit and lower 6-digit (total of
9 digits) display. The position of the dots on the upper part of the screen
indicates which digits are displayed.
∗
Products with tiny scratches, marks, or display colour or brightness variations which
do not affect the performance of the product are verified as conforming products.
For flow switch precautions and specific product precautions,
refer to the “Operation Manual” on the SMC website.

IN Side Straight Piping Length and Accuracy (Reference Data)
• The piping on the IN side must have a straight section of piping with a length of 8 cm or more.
If a straight section of piping is not installed, the accuracy can vary by approximately ±2 % F.S.
∗“Straight section” means a part of the piping without any bends or rapid changes in the cross
sectional area.
• When the PFMC7501 or 7102 is connected to tubing, use a tube I.D. 9 mm or more just before
the product. The accuracy can vary by approximately ±2 % F.S. when such tubing is not used.

∗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, be sure to keep a sufficient
margin. Otherwise, chattering will occur.
∗5 Setting is only possible for models with analogue output.
∗6 Setting is only possible for models with external input.
∗7 Setting is only possible for models with the units selection function.
∗8
The response time indicates when the set value is 90 % in relation to the step input.
∗9 The accumulated flow display is the upper 6-digit and lower 6-digit (total of
12 digits) display. When the upper digits are displayed, x 106lights up.
∗
Products with tiny scratches, marks, or display colour or brightness variations which
do not affect the performance of the product are verified as conforming products.
For flow switch precautions and specific product precautions,
refer to the “Operation Manual” on the SMC website.
