The density sensor RHOTEC continuously measures the density of liquids according to the oscillating U-tube principle. The instrument is designed for applications requiring maximum sensitivity and highest accuracy. It is easy to operate and maintenance-free. For density measurement the liquid flows through a thin U-shaped tube inside the sensor. Even the smallest changes in fluid density have an impact on the detected signal and are identified with highest precision. As a specific property of each liquid, the correlation between concentration and density can be described by a mathematical polynomial. Any temperature drifts of the measured signal are automatically compensated for by an internal Pt1000 sensor. RHOTEC can display liquid density and solution concentration in various units.
