Flow computer Thermo Scientific Process Systems

The lightning fast Thermo Scientific AutoEXEC flow computer and remote telemetry unit integrates measurement and control functionality for both natural gas and petroleum liquids. This highly accurate system calculates flow on four to 32 runs at an unprecedented rate of 10 times per second. It solves complicated AGA equations and is compliant with API Ch. 21.1 and Ch. 21.2. It features a preloaded default configuration; USB connectivity via three ports: host, slave-device and on-the-go (OTG); secure access controls; authentication and built-in encryption; built-in lightning protection on each board; a processor that operates at the widest temperature range in the industry: -40 C (-40 F) to 85 C (185 F); and AO accuracies of ±0.1% over the full temperature range. The standard AutoEXEC includes a CPU board, power supply and an enclosure with six available board slots. Optional boards can be added to increase input/output as necessary and each board has its own 32-bit ARM 7 industrial grade processor, enabling the most rapid communication to the motherboard. Seven additional chassis can be daisy-chained together to obtain tremendous input/output and meter run capabilities. Remote installation requires that the AutoEXEC be manufactured to endure the harshest elements. The board withstands 120 indirect lightning strikes of 6,000 volts/3,000 amps each and temperature cycling from -40°C (-40°F) to 85°C (185°F). Analog output accuracies of ±0.1% are ensured over the full temperature range. Multiple surge protection schemes are also installed on each board.
