About the 7829 Viscomaster Dynamic
The Micro Motion
®
7829 Viscomaster Dynamic
™
is a
proven technology for the accurate, continuous real-
time measurement and control of liquid viscosity.
The 7829 Viscomaster Dynamic viscosity meter has
been designed for installation in fuel oil applications
that supply engines, turbines, and burners in on-
shore and off-shore applications.
As part of its unique and rugged design, the 7829
Viscomaster Dynamic viscosity meter directly
measures dynamic viscosity and temperature. The
meter is also programmable to output calculated
density and kinematic viscosity measurements. The
Viscomaster Dynamic can easily cope with a range
of fuels from heavy fuel oil (HFO) to marine gas oil
(MGO).
The Viscomaster Dynamic has worldwide marine-
industry approvals including Lloyds Register, GL,
DNV, ABS, and BV. For a complete list of marine
approvals, see “Marine approval classifications” on
page 7.
Advantages
• Fully integrated “fit and forget” digital viscosity
and temperature measurement for monitoring
and control
• Two 4–20 mA outputs of kinematic viscosity and
temperature
• Modbus/RS-485 communications output of all
parameters, including calculated density and
calculated kinematic viscosity at operating
temperature
• Continuous measurement
• No moving parts means virtually no
maintenance
• PFA-coated tines for asphaltene rich fuels
• Integral Class B PT100 temperature sensor
• Hazardous-area approved (ATEX and CSA)
• Insensitive to vibration
• Direct insertion meter suitable for high-line
pressure
• PC configuration tools for diagnostics and data
