As a highly sensitive indicator of change in product quality, viscosity is increasingly recognised as one of the most important industrial process measurement parameters.

Solartron Mobrey specialises in the manufacture of process viscosity transmitters, digital viscometers and complete viscosity control systems (skids). Our products are replacing many existing technologies such as:

- Process capillary
- Falling ball
- Orifice
- Vibrational

Mobrey viscometers, viscosity transmitters and viscosity control systems (skids) are being used in applications where previously only laboratory measurements could be made.

Mobrey vibrational and rotational techniques can measure most process fluids, even under difficult conditions such as marine environments. These measurement technologies are generally used for quality and process control in production processes such as blending, coating and spraying.


The 7829 Viscomaster Series Viscosity transmitters from Solartron Mobrey are used for the measurement and control of heavy fuel oil (HFO) in marine and power applications. The 7829 Viscomaster and 7829 Viscomaster Dynamic Viscosity Transmitters are a major innovation in the measurement of all types of fuel oil that supply engines, turbines and burners.

The 7829 Viscomaster simultaneously measures real-time viscosity, density and temperature and can be configured to output either dynamic or kinematic viscosity.

As a vibrating element transducer, the 7829 Viscomaster complements the 7829 Visconic and 7827 Digital Viscometer, and incorporates all the advantages that this technique has over capillary, orifice and rotational viscometers. As an established, proven design, the 7829 Viscomaster has been approved by Lloyds Register for Marine environments and has a wide range of equivalent worldwide Marine approvals.

-No moving parts - Minimal maintenance
-Continuous measurement of viscosity, density and temperature
-Referred viscosity and density measurements
-User configurable 4-20mA output
-PTFE coated sensor that resists product/asphaltene build-up
-MODBUS output of all parameters
-Adapters available for existing technology marine viscometers
-PC-based configuration tool


-Marine & Power Heavy fuel oil burner control
-Fuel booster modules
-Turbine oil viscosity control
-Retro-fit of existing technology viscometer technologies


The 7829 Viscomaster and 7829 Viscomaster Dynamic Viscosity Transmitters are a major innovation in the measurement of all types of fuel oil that supply engines, turbines and burners.

In a similar fashion to the 7829 Visconic, the 7829 Viscomaster Dynamic Viscosity transmitter incorporates a stand-alone electronics module with a configurable integral 4-20mA and a Modbus RS485 communication output.

As an established, proven design, the 7829 Viscomaster Series Viscosity transmitters have been approved by Lloyds Register for Marine environments and ha a wide range of equivalent worldwide Marine approvals.
