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.

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

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.

*1 Air quality grade is JIS B 8392-1:2012 [4:6:-] and ISO 8573-1:2010 [4:6:-].
*2 Set point range will change according to the setting of the zero cut-off function.
*3 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 pres-
sure is 0.5 MPa). Do not release the OUT side piping port of the product to the atmosphere without con-
necting piping. If the product is used with the piping port released to atmosphere, accuracy may vary.
*5 The time from when the ow is changed by a step input (when the ow rate changes from 0 to
the maximum value of the rated ow range instantaneously) until the switch output turns ON (or
OFF) when set to be 90% of the rated ow rate
*6 If the ow uctuates around the set value, the width for setting more than the uctuating
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 ow is changed by a step input (when the ow rate changes
from 0 to the maximum value of the rated ow range instantaneously) until the analog
output reaches 90% of the rated ow rate
*10 Analog output or external input can be selected by pressing the buttons.
*11 The ow rate given in the specications is the value under standard conditions.
*12 Setting is only possible for models with the units selection function.
*13 Display range will change according to the setting of the zero cut-off function .
*14 The accumulated ow 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 veried as conforming products.
For ow switch precautions and specic product precautions,

*2 Set point range will change according to the setting of the zero cut-off function.
*3 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 pres-
sure is 0.5 MPa). Do not release the OUT side piping port of the product to the atmosphere without con-
necting piping. If the product is used with the piping port released to atmosphere, accuracy may vary.
*5 The time from when the ow is changed by a step input (when the ow rate changes from 0 to
the maximum value of the rated ow range instantaneously) until the switch output turns ON (or
OFF) when set to be 90% of the rated ow rate
*6 If the ow uctuates around the set value, the width for setting more than the uctuating
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 ow is changed by a step input (when the ow rate changes
from 0 to the maximum value of the rated ow range instantaneously) until the analog
output reaches 90% of the rated ow rate
*10 Analog output or external input can be selected by pressing the buttons.
*11 The ow rate given in the specications is the value under standard conditions.
*12 Setting is only possible for models with the units selection function.
*13 Display range will change according to the setting of the zero cut-off function .
*14 The accumulated ow 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 veried as conforming products.
For ow switch precautions and specic 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
ow switch, causing a backow of air, the measured value will change.
