Thermal mass wo sensor principles
Order example
Mounting accessories
Symmetric
temperature prole
(a) No ow
In the absence of ow, the heat
from the heater spreads evenly
left and right, so the temperature
distribution is like (a).
(b) Small ow
When ow begins, the inlet side
is cooled by the ow, the outlet
side is warmed by the heat of the
inlet side of the heater, and the
temperature distribution is like (b).
(c) Large ow
When the ow increases, it
becomes a distribution like (C).
Since the temperature distribution
before and after the heater is
proportional to the ow rate, the
ow rate can be determined from
the ratio.

*2. When using window comparator mode, the difference between two set points must be greater
than the xed hysteresis, otherwise will cause the switch output to malfunction.

MF01 Installation instructions
Installation instructions
●Piping
Install the pipe by following the arrow indication that shows
the air ow direction on the product.
Use straight piping 8cm or longer to connect the Piping Port
(Inlet side).
If straight piping is not installed, the accuracy may vary by ±
2% F.S..
* Straight Piping: The pipe is without bending and the cross
sectional areas of the pipe keeps the same.
Blow the air to ush out the foreign matters, dust and etc.
before installing the pipe.
Uncleaned air may cause malfunction or damage to the
product.
Piping for the One-Touch Fitting, insert the tube rmly into the
tting and make sure it cannot be pulled out.
Also using the proper tube cutter is recommended to ensure
square edge tube.
●Mounting Bracket / Optional Parts
The LCD display may be difcult to see at certain angles.
The sensor can be installed horizontally or vertically, but
the ow rates
may change because of the installation way of the product
or piping.
The tightening torque for screws should be under 0.5 ±0.1
N.m.
* The tightening torque for bracket mounting screws should
be under 0.5 ± 0.1 N.m.
