Emerson introduces new meter for demanding processes

Emerson Process Management has released a direct insertion density and concentration meter designed for aggressive applications.

The Micro Motion Fork Density Meter is the next generation of the Micro Motion 7826 and 7828 direct insertion density meters. Incorporating the same tuning fork design as its predecessors, the Fork Density Meter is built to tackle process applications such as pipeline interface detection, mineral slurry solids monitoring and corrosive acid concentration control.

The meter incorporates a hazardous area head-mounted transmitter that has the flexibility to digitally connect to distributed control systems (DCS) as well as output raw sensor signals to signal converters and flow computers.

With the implementation of HART and RS485 Modbus digital I/O communications, the meter has the capability to accept external signals from other field instrumentation such as temperature, pressure and volumetric flow devices.

The input of these external measurements enables it to calculate and output enhanced process measurements such as mass flow and net solids flow, while still minimising installation and cabling costs.

Also incorporated is a new diagnostic capability called Known Density Verification that checks the meter for measurement alarm conditions, sensor integrity and the presence of coating, erosion or corrosion.

This new technology expands the availability of diagnostics information in critical density measurement applications, resulting in significant reductions in maintenance costs and cycle times.
