Direct-Insertion Density Meters Handle Demanding Process Applications

emerson0310

Emerson Process Management has released the Micro Motion fork density meter, the next generation of the Micro Motion 7826 and 7828 direct insertion density meters. The fork density meter has been built to tackle demanding process applications, such as pipeline interface detection, mineral slurry solids monitoring and corrosive acid concentration control.

The direct-insertion meter is suitable for solving common day-to-day issues, such as reducing product give-away, minimizing cross-contamination on multi-product pipelines and ensuring operator safety when sampling hazardous liquids. It’s also been designed for applications where fast-response density and concentration monitoring is required, even when the installation footprint is limited.

The meter incorporates a hazardous-area, head-mounted transmitter that has the flexibility to digitally connect to distributed control systems as well as output raw sensor signals to signal converters and flow computers.  The meter supports WirelessHART, 4-20mA, HART, sensor time period, Foundation fieldbus and RS485 Modbus communications.

With the implementation of HART and RS485 Modbus digital I/O communications, the Micro Motion fork density 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 the meter to calculate and output enhanced process measurements, such as mass flow and net solids flow, while still minimizing installation and cabling costs.
