Emerson Process Management has introduced the Micro Motion Heavy Fuel Viscosity Meter (HFVM) Viscomaster, the next generation of the Micro Motion 7829 Viscomaster direct insertion viscosity and density meter. The HFVM incorporates a robust, low-friction, diamond-like carbon (DLC) coating that is suitable for tackling demanding process applications such as marine heavy fuel oil (HFO) combustion control, marine gas oil (MGO) viscosity control and land-based fired heaters.

The head-mounted transmitter is hazardous area approved and has the flexibility to connect to control systems via a wide range of digital and analog protocols. System integration and start-up commissioning costs are said to be reduced due to the support from 4-20 mA, HART, wireless HART and RS485 Modbus communications. The product accepts and processes external signals from other field instrumentation such as temperature and mass/volumetric flow devices, enabling the meter to calculate and output enhanced process measurements while minimising installation and cabling costs.

The HFVM also incorporates a diagnostic capability called Known Density Verification (KDV) that checks the meter for measurement alarm conditions, sensor integrity and the presence of coating, erosion or corrosion. This technology expands the availability of diagnostic information in critical viscosity and density measurement applications, which can result in significant maintenance costs and cycle time reductions.
