Measure Density and Determine Product-Specific Concentration
 
RHOTEC continuously measures density using the oscillating U-tube principle, for example in acids, alkalis, fats, emulsions and solvents. Concentration is determined from density using a suitable product-specific mathematical relationship.
 
Measuring Principle
 
Density measurement is based on the oscillating U-tube principle. Even small density changes affect the measurement signal. The measured density can be used to determine concentration with a suitable product-specific polynomial.
 
Applications
 
 
 
Acids
 
 
Alkalis
 
 
Fats
 
 
Emulsions
 
 
Solvents
 
 
Phase Detection
 
 
Crystallisation Processes
 
 
Temperature drift of the measurement signal is automatically compensated. European patent application: 1 439 438 B1.
