Temperature Coefficients 

 
 

 
 

 
 

 

Note: 

Water temperature coefficients can be used 
for many low concentration products, such 

as milk, beer, whey, starch suspension, etc. 
For upgraded milk, whey, cottage cheese, 

etc. the values given for sugar solution can 
be used with good approximation.
