4.1 Notes on Selecting the Installation Location
Do not store or install the flowmeter in :
1.
Places within the immediate proximity of equipment producing electrical interference (such as
motors, transformers, radio transmitters, electrolytic cells, or other equipment causing
electromagnetic or electrostatic interference).
motors, transformers, radio transmitters, electrolytic cells, or other equipment causing
electromagnetic or electrostatic interference).
2.
Where there is direct sunlight.
3.
Where excessive vibration or mechanical shock occurs.
4.
Where high temperature or high humidity conditions obtain.
5.
Where corrosive atmospheres exist.
6.
That can be submerged under water.
7.
Where there is a sloped floor. To put the flowmeter temporarily on the floor, place it carefully
with something, such as a block, to support it so that the flowmeter will not topple over.

9. Avoid places where fluid runs in a pulsating form.
10. Design piping so that the detector pipe is always filled with fluid, whether the fluid is flowing

Places where there is following factors.
◆
Factors to impede infrared switch to operate properly
・
Intense light such as direct sunlight and reflected sunlight by window glass or metal plate
・
Place where brightness changes suddenly such as lighting being turned ON/OFF
・
Dense smoke or steam near the control panel
・
Those attached on the control panel such as rain (dew drop), snow, ice, mud and oil, and haze due to
their attachment
their attachment
・
Light reflecting object near the control panel, or reflecting object such as metal plate placed opposing
to the control panel
to the control panel
When any of above factors is considered, take a measure for the proper operation of infrared switch such
as to place a cover or to secure a space for at least a person to stand in front of the control panel.
When unable to avoid above factors, operate the EMF converter removing the factor by covering the
control panel by hand so that light does not shine on it, by cleaning those attached on the control panel,
or by standing in-between the reflecting object and the control panel to block the light.
