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 LF654 series flowmeters, refer to Tables 4 and 5 (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
6. Other items
Specifications other than standard items
Consult a Toshiba representative when choosing materials for lining, electrodes, and grounding rings.
