Calibration Range
If the calibration range is not specified, the standard
range as shown below will be used. If the range is
specified, we will use the specified range for
calibration.

Note: The unit of "gal/min" is not exchanged
(converted) by "m 3 /h".
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.
• 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.
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

Flow calibration data: (required or not)
6. Other items
Specifications other than standard items
Consult a Toshiba representative before ordering
when choosing materials of the wetted parts such as
lining, electrodes, and grounding rings.
