About establishment environment
Do not store or install the flowmeter:
• Where there is direct sunlight.
• Where excessive vibration or mechanical shock
occurs.
• Where high temperature or high humidity
conditions exist.
• Where corrosive atmospheres exist.
• Places that can be submerged under water.
• When placing the flowmeter temporarily on the
floor, support it, i.e., with a block so that the
flowmeter does not topple over.
In areas like the following, there may be the case that
infrared switches do not function correctly. (If these
are unavoidable, use an appropriate cover.)
(1) Where unit (operation panel) is exposed to direct
sunlight, reflection of light onto window pane
and diffused light reflection.
(2) Where smoke and steam may occur.
(3) Where exposed to direct snow, ice or mud.
Ordering Information
