IM 01G05B03-01E 1st Edition 

*7: The couplant weatherproof type is recommended for 

permanent installation in the outdoor, etc. It is adhesive 
liquefied rubber and tight contacts between transducers 
and pipe surface can be obtained by curing it. It usually 
takes one to three days for complete curing depending on 
the conditions. The operating condition of ambient 
temperature is as below. 
Before and during curing : 0 to +50°C / 32 to 122°F 
After curing : –40 to +180°C / –40 to 356°F
