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.

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
1. When ordering the LF430 series flowmeters, refer to
Tables 6 and 7 (Type Specification Codes).
An entry must be made for each of the columns in
each of these tables.
2. Fluid characteristics:
(1) Type of fluid to be measured and its characteristics
(2) Fluid temperature
(3) Fluid pressure
(4) Electrical conductivity of the fluid
3. Measuring range
4. I/O function setting
5. Ordering scope:
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.
Toshiba International Corp. (Houston) stocks
Hazardous location certification type
flowmeters as standard inventory.
