Direct insertion density & concentration meter!

Fork Density meter helps users achieve fast-response density and concentration monitoring in challenging conditions

The next generation of Emerson's market-leading Micro Motion 7826 and 7828 direct insertion density meters has been released. Incorporating the same rugged and reliable tuning fork design as its predecessors, the Fork Density Meter is built to tackle the most demanding process applications such as pipeline interface detection, mineral slurry solids monitoring and corrosive acid concentration control.

The direct insertion Fork Density Meter is the ideal choice for solving problems that customers face on a daily basis, such as reducing product give-away, minimising cross-contamination on multi-product pipelines and ensuring operator safety when sampling hazardous liquids. It is designed for applications where fast-response density and concentration monitoring is required, even when the installation footprint is limited.

The Fork Density 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 4-20mA, HART®, WirelessHART®, Sensor Time Period, FOUNDATION fieldbus and RS485 Modbus communications all supported, the system integration and start-up/commissioning costs are significantly reduced.

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 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.

The Fork Density Meter also incorporates 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.
