Model 2000

The Elster-Instromet real-time flow computer series are designed for hydrocarbon liquid and gas measurement and control applications. The advanced features support flexible configurations for fiscal and custody transfer measurements based on volume, mass and energy calculations using the latest applicable AGA, ISO and API standards available. The flow computers (single- or multiple stream) support turbine, rotary, ultra-sonic, orifice, density, venturi and coriolis flow meters. Alternative the flow computers can be used as a system component serving station controller, liquid prover / grab sampler and/or valve & PID loop controller functionalities. The top range flow computers provide remote control capabilities using web-based Ethernet TCP/IP technologies including remote front panel operations.
