 
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.
