VAF Viscotherm® V-92

Series V92 Model VC Electronic Component System


The benefits of accurate viscosity control
with Viscotherm:
Viscosity control of fuel oil for combustion engines is a necessity because of unpredictable quality of fuel.

Prevention of engine damage and reduction of maintenance, next to efficiency
improvement, are essential to the financial bottom line.

Your advantage using Viscotherm V92
Designed to save time and raw material
in-line measurement of viscosity will give you
the possibility to optimise your process and
instantly obtain the required quality of final
product. No samples have to be taken and
bulky mixing vessels are no longer necessary.
