On-line Continuous Density Measurement

Dynatrol^® Density System is designed for the measurement of density in familiar units such as specific gravity, API gravity, Baumé, BRIX, as well as being able to measure the percent solids or percent concentration of a liquid or slurry.

Dynatrol Density System achieves exceptional accuracy over a wide range of process changes in ambient temperature, pressure, viscosity or flow.

Principle of Operation

The media under test flows through the internal U-tube portion of the Dynatrol cell. The ½" tubing is driven into mechanical vibration by the electrically excited drive coil. As the density or specific gravity of the media increases or decreases, so does the effective mass of the U-tube, changing the frequency of vibration. The pick-up end, consisting of an armature and coil arrangement, senses the vibration and provides an output that is a function of the density, specific gravity or percent solids of the proces
