The C581 is the first model in an exciting new lineup of powerful and versatile Flow & Energy Computers. It combines our extensive expertise in instrumentation, a deep understanding of international requirements, and a commitment to user-friendly design. The result? The most robust, accurate and versatile field mount Flow & Energy Computer available today. The C581 sets a new standard for performance and reliability, leading the way in a promising range of Flow & Energy Computers!

Accurate

The C581 single stream flow and energy computer is a powerhouse for precision measurement. It accurately measures flow, temperature, and pressure of water or steam, and uses IAPWS density and enthalpy determinations to precisely calculate energy, mass, and volumetric flow. Thanks to 11 linearization points for all input signals, you'll experience enhanced accuracy across all flow ranges.

Flow measurement
The C581 can handle all ISO5167 flow elements and more; either with signals form a single dP sensor up to 3 stacked or averaged dP sensors.  As such range and accuracy at the lower end of the flow spectrum is significantly improved. For other applications the flow calculation can be based at the design conditions of the flow element.  Pulse inputs are soon available for the measurement of rotating flow meters. The C581 is able to determine the energy transfer in heat exchangers.

Robust and weatherproof
Built to endure the toughest environments, our robust IP66/67, Type 4X aluminum field enclosure withstands extreme weather and harsh industrial conditions. It’s engineered to perform flawlessly in temperatures ranging from a -40°C/-40°F to +70°C/+158°F. With this rugged enclosure, the C581 stays protected, no matter what nature or the job throws at it!
