Oil and gas test system saves £100,000

17 December 2008

The mass of gasses and liquids are affected by changing temperature and pressure, therefore a flow computer is required to calculate the mass flow rate of a fluid. The flow computer takes readings from volumetric flow meters, temperature and pressure sensors.
The flow computers have sixteen 4-20mA input signals, RS485 Modbus communications and twelve alarm relays.

A real-time system based on a DAP (Data Acquisition Processor) is used to control all the outputs and inputs. This data acquisition card uses an on-board microprocessor and its own operating system to manage hundreds of input and output channels. “Pipes” are used for data to flow through the DAP architecture, independently from each other and the PC’s operating system.

This system comprises of two DAP cards, 32 eight channel analogue output cards and 12 digital input cards installed in two further 19” rackmount enclosures.

The system complies with COTS (Commercial Off The Shelf) product requirement that enables a saving of over £100,000 compared to the cost of developing an in-house system.
