The diagnostic bit in the cyclic process data makes it easy to find problems with the equipment.
It is possible to find problems with the equipment in real time using the cyclic (periodic)
data and to monitor such problems in detail with the noncyclic (aperiodic) data.

Both the flow rate and pressure can be measured with 1 product.
The installation of a digital pressure switch and a cross spacer is not necessary, thus reducing
the face-to-face and depth dimensions. In addition, only 1 cable is required for wiring. This
reduces the required installation space, piping, and wiring work.

When using the accumulated value hold function, use the operating conditions to calculate
the product life, and do not exceed it. The maximum update 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
When the pressure range is 1.0 to 1.5 MPa, the pressure characteristics will be ±5% F.S.
(standard pressure is 0.5 MPa). Do not release the OUT side piping port of the product to
the atmosphere without connecting piping. If the product is used with the piping port re-
leased to atmosphere, accuracy may vary.

changes from 0 to the maximum value of the rated flow range instantaneously)

the fluctuating width needs to be set. Otherwise, chattering will occur.
*7 Analog output or external input can be selected by pressing the buttons.
Refer to the graph for analog output.
*8
When selecting 0 to 10 V, refer to the analog output graph for the allowable load current.
*9 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 analog output reaches 90% of the rated flow rate

1/2 (PF3A702H) and the product is operated at a supply pressure of 0.5 MPa
*7
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
*8 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.
*9 Analog output or external input can be selected by pressing the buttons.
Refer to the graph for analog output.
*10 When selecting 0 to 10 V, refer to the analog output graph for the allowable
load current.
*11 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 analog output reaches 90% of the rated flow rate
*12 Analog output or external input can be selected by pressing the buttons.
*13 The flow rate given in the specifications is the value under standard
conditions.
*14 Setting is only possible for models with the units selection function.
*15
Display range will change according to the setting of the zero cut-off function.
*16 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 color 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.

Products do not come assembled. They should be ordered
separately and assembled by the customer.
∗Avoid mounting the lubricator on the inlet side.
∗If a pressure relief 3-port valve is installed on the inlet side of the digital
flow switch, causing a backflow of air, the measured value will change.
