Emerson Process Management has released its Micro Motion® Fork Density Meter, the next generation in its Micro Motion 7826 and 7828 direct insertion density meters. Incorporating the same tuning fork design as its predecessors, the Fork Density Meter is built for such highly demanding process applications as pipeline interface detection, mineral slurry solids monitoring, and corrosive acid concentration control. The meter is designed to prevent loss in general or cross-contamination on multi-product pipelines, as well as to help ensure operator safety when sampling hazardous liquids. It is designed for applications where fast-response density and concentration monitoring is required in areas with limited installation space. The new meter’s head-mounted transmitter communicates to distributed control systems (DCS). It also can output raw sensor data to signal converters and flow computers. Communications protocols include 4-20mA, HART, WirelessHART, Sensor Time Period, Foundation fieldbus and RS485 Modbus. HART and RS485 Modbus digital I/O enables the Micro Motion Fork Density Meter accept signals from other field instrumentation including temperature, pressure and volumetric flow devices. The meter can then calculate and output, among others, mass flow and net solids flow. The Fork Density Meter also incorporates Known Density Verification, a new diagnostic that checks the meter for measurement alarm conditions, sensor integrity and the presence of coating, erosion or corrosion.
