CiDRA Corporation”s SONARtrac flow monitoring systems with FOUNDATION Fieldbus have successfully completed interoperability testing and are now officially registered with the Fieldbus Foundation. As such, SONARtrac systems are now available with a choice of MODBUS or FOUNDATION Fieldbus, in addition to 4-20mA current outputs with HART, providing multiple options for integration into control systems. All SONARtrac flow monitoring systems are available with Class I Division 2, or ATEX Class I Zone 2 hazardous-area certifications. These certifications allow CiDRA to address customer needs in oil and gas, oil sands refining, chemical processing, and other hazardous-area applications around the globe. SONARtrac systems are capable of providing multi-variable measurements, such as volumetric flow, speed of sound, and entrained air/gas, in a wide variety of fluid regimes, including liquids, gases, slurries, and multiphase fluids. These systems are robust, full-bore clamp-on solutions and scalable to large pipe diameters. This means that there is no restriction to the flow, no need to cut the pipe, and therefore no process downtime or disruption during installation.
