Viscosity Process Analyzer VISC-4 Application The BARTEC BENKE Viscosity Process Analyzer (VISC-4) is a continuously kinematic viscosity measuring capillary analyzer suited to measure the viscosity of a product. The VISC-4 operates online. It serves to monitor/maintain product quality for the in-spec production of mineral oil products. Three basic variants are available: measuring temperature 20 to 60°C (68 to 140°F) measuring temperature 41 to 60°C (106 to 140°F) measuring temperature 61 to 100°C (142 to 212°F) Each variant available with following measuring ranges: viscosity 0.7 to 30 cSt viscosity...

Norms and Standards ASTM D 445 DIN EN ISO 3104 IP 71 Method The value of kinematic viscosity results from the product of the measured passage time and the device constant of the capillary: v = C * t. As viscosity is highly dependent on the temperature, the temperature of the liquid during the measurement has to be regulated precisely with minimum variation (0.02 K in accordance with ASTM D 445). For a continuous determination of the viscosity of a liquid during the production process the liquid is controlled in viscometers through a capillary. From the mass flow rate through the capillary and...
