Functions
Can be set between 0 and 60 s
The delay time can be set according to the
application.
Application example
When 5 V output is required
from the flow switch at 75 L/min,
use a sensor that outputs 1 to 5 V
at 1 to 100 L/min.
The analog span point (5 V
(10 V), 20 mA) can be
changed within 10 to 105%
of the rated flow rate with
respect to the displayed
value.

2-Color Display Digital Flow Switch PF2M7(-L) Series

Select a digital flow switch to increase
energy savings!
Flow control
is necessary for promoting en-
ergy 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.
M/C
M/C
M/C
Main line flow control
Flow control for each branch line
Applications
For welding machines
For leak testers
For N2gas cylinder peripheral equipment
For the control of metal wire tension For air blow
For suction verification
The accumulated indication shows
the operating flow rate or residual
amount (of N2, etc.) in a gas cylinder.
Detection camera
Models compatible with argon (Ar)
and carbon dioxide (CO2) mixed
gas are available.
*Please contact SMC for details.
¡For flow control of N2gas to
prevent lead frame oxidation
¡N2blow prevents the
distortion of camera images
due to air turbulence.

2-Color Display Digital Flow Switch PF2M7(-L) Series

Implement diagnostic bits in the process data.
Supports the IO-Link communication protocol
IO-Link is an open communication
interface technology between the sensor/
actuator and the I/O terminal that is an
international standard: IEC61131-9.
IO-Link Master
Device settings
can be set by the
master.
• Threshold value
• Operation
mode, etc.
Read the device data.
• Switch ON/OFF signal and analog value
• Device information:
Manufacturer, Product part number, Serial number, etc.
• Normal or abnormal device status
• Cable breakage
Application Example
Configuration File (IODD File*1)
· Manufacturer · Product part no.
· Set value
*1 IODD File:
IODD is an abbreviation of IO Device
Description. This file is necessary for setting
the device and connecting it to a master. Save
the IODD file on the PC to be used to set the
device prior to use.
For the predictive maintenance of
suction verification
The flow rate “switch ON/OFF signals” and
“analog values” are monitored to determine
the suction status. The process and
suction status can then
be compared.

Diagnosis Switch output
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.
