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 10 to 500 cSt

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 fl ow rate through the capillary and from the pressure drop over the length of the capillary, the current value of the kinematic viscosity of the liquid is ascertained by applying the law of Hagen-Poiseuille.
