Dynatrol Digital Viscosity Converter

Dynatrol® Digital Viscosity Converters

Dynatrol® Series 3000 Digital Viscosity Converters were designed for use with all Dynatrol® Viscosity Systems. Using microcontroller technology, the digital converter accepts information from a Dynatrol® Viscosity Probe and calculates the viscosity of the liquid under test. The Series 3000 converter mathematically computes and displays the viscosity in standard units.

General Information

Dynatrol® viscosity measurement probes utilizes a vibrating rod immersed in the process media. The design is without recesses, packing or wearing parts.

Principle of Operation

Dynatrol® Cells produce frequencies that are mathematically related to the density of the fluids passing through them. The digital converters use two known product frequency values as reference points, the air frequency value and the water frequency value. Calibration is achieved using these two values.
