The MAR - IN - CONTROLS VISCOTROL is an heavy duty on line
viscosity meter designed to measure and control viscosity
of low-grade and intermediate heavy fuel oils, with the highest
possible degree of reliability. The measuring system is based
on a gear type-metering pump, which with draws the fuel sample
from the mainstream and propels it continuously through a
capillary. In the pressure drop across the capillary is proportional
to the absolute viscosity in mPas.
Features
Fast Response.
Back -flow pattern prevents poor heat transfer in measuring
section.
Trouble Free Operation.
The viscotrol body transmitter fixing arrangement assures
proper installation and no malfunctioning of the viscosity
measurement system after it has been put into operation.
Free of Oil Sediment Build
up. The Fluonplastic (Teflon) coated steel oil sediment
repellent measuring capillary prevents build up of oil
sediment deposits to the capillary wall. Poor quality
heavy fuel oils will not effect viscosity measurement.
Simple to Install, to
operate and to maintain.
High viscosity measurement
precision.

Why Viscosity Control?
Viscosity control instead of temperature control has the
following advantages:
Improved
combustion efficiency. The injected fuel
has the proper degree of atomization thus droplet size.
Less
maintenance. Periods between over hauling
pistons and valves increase.
Reduced
lubrication oil cost. Less unburned combustibles
will cut down the consumption of lubrication oil.
Carbonization
prevention of the fuel valve nozzle.
A too low viscosity of the heavy fuel oil causes gasification
with as result the formation of carbon at the nozzle outlet,
which causes poor atomization of the fuel.
Less
corrosion in boilers. Both the proper
atomization as the proper air/ fuel ratio cut down the
SO2 and SO3 content.
