Elster-Instromet real-time flow computers are designed for liquid hydrocarbon and gas measurement and pressure control applications. The advanced features support flexible configurations for custody and non-custody transfer measurements based on volume, mass and energy calculations using the latest AGA, ISO and API standards available. The (single or multiple stream) flow computers support turbine, rotary and ultrasonic meters, as well as orifice, density, Venturi and Coriolis mass flow meters. Alternatively, the flow computers can be used as system components which fulfil station controller, liquid prover, grab sampler and valve & PID loop controller functions. The top range flow computers provide remote control capabilities using web-based Ethernet TCP/IP technologies including remote front panel control.
