ControlEdge RTU Gets Liquid Flow Capability


ControlEdge Remote Terminal Unit (RTU) now offers measurement of both gas and liquid flow. The latest version of the product also offers expanded HART support, which allows for easier device commissioning and diagnostics.


The electronic flow metering capability supports liquid custody transfer per the American Petroleum Institute (API) 21.2 guidelines in North America. This latest release increases the efficiency of remote asset management by doubling as a flow meter, as well as allowing operators to automate loop check and commissioning, reduce hard-wired input/output (I/O) devices, and extend device diagnostics. 


ControlEdge RTU is part of Honeywell’s next generation family of controllers, leveraging the power of the Industrial Internet of Things (IIoT). It reduces equipment monitoring and diagnostic time from hours to minutes and significantly decreases configuration time. The RTU is able to withstand harsh environments and is designed for easy deployment at remote sites, in applications such as wellhead monitoring and control, data concentrators, gas flow metering, block-valve automation, and pump and compressor control, as well as in water distribution and wastewater treatment. Featuring native redundancy, the controller complements the C300 and Series-C platform used in Honeywell’s Experion Process Knowledge System (PKS) to provide a fully integrated solution.



  • Operates in harsh environments with low power consumption – ideal for remote installation and operation on solar power
  • Increased availability through native controller redundancy – no switch required for I/O communication
  • Hart-enabled onboard I/O and expansion I/O modules
  • Removable and plug-in terminal blocks simplify wiring and reduce time for cabinet assembly
  • A new onboard wireless I/O solution– no specialized modules needed to integrate ISA100 instruments. Both wired and wireless I/O devices are programmed and managed with same configuration tool. 
  • Built-in HART I/O, and ISA100 field instrument integration with Field Device manager
  • Efficient remote management across hundreds to thousands of RTUs Reduce equipment monitoring and diagnostic time from hours to minutes.
  • Electronic Flow Metering (EFM) capability for both gas and liquids per API 21.1 and 21.2
