Emerson Process Management has released the next generation of the market-leading Micro Motion 7826 and 7828 direct insertion density meters.
The Micro Motion fork density meter incorporates the same rugged and reliable tuning fork design as its predecessors, and is built to tackle demanding process applications such as pipeline interface detection, mineral slurry solids monitoring, and corrosive acid concentration control.
Suitable for solving problems such as reducing product give-away, minimising cross-contamination on multi-product pipelines and ensuring operator safety when sampling hazardous liquids, the direct insertion Micro Motion fork density meter is designed for applications where fast-response density and concentration monitoring is required, even when the installation footprint is limited.
Key features of the direct insertion Micro Motion fork density meters include hazardous area head-mounted transmitter with the flexibility to digitally connect to distributed control systems (DCS) as well as output raw sensor signals to signal converters and flow computers; support for 4-20mA, HART, WirelessHART, Sensor Time Period, Foundation fieldbus and RS485 Modbus communications, which reduces system integration and start-up/commissioning costs; and capability to accept external signals from other field instrumentation such as temperature, pressure and volumetric flow devices thanks to HART and RS485 Modbus digital I/O communications.
The input of these external measurements enables the fork density meter to calculate and output enhanced process measurements such as mass flow and net solids flow, while still minimising installation and cabling costs.
A new diagnostic capability in the fork density meter called Known Density Verification 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 reduction in maintenance costs and cycle times.
