Flow computer

Additional to natural gas, some flow computers offer an array of density calculations for steam, oxygen, hydrogen, nitrogen, and ethylene.

API MPMS Chapter 11.1 (2004), NIST 1045 and IUPAC for ethylene measurement, GPA TP-27 for LPGs and NGLs are amongst an array of calculations performed by liquid flow computers.

Flow computers are available as completely programmable devices using a variety of software tools or as configurable devices using manufacturer's specific configuration software packages to set up interfaces to gas chromatographs, gas ultrasonic meters, liquid provers, flow control valves, PLC, DCS, SCADA and industry-recognized HMI supervisory systems.

A key component in custody transfer systems, flow computers can be approved to metrological and quality standards such as OIML R117-1 for liquids, EN12405 for gas, WELMEC 7.2 for software development, and ISO 9001:2008.

These are considered key selection criteria for flow computers that are installed in Europe, Middle East, Asia and also Latin America.
