A. General Operational Data Management (DM) involves • - the acquisition of data [28] • - the transmission of data from local sites to operations • - the archiving and presentation of data and reports Such a system requires; • - a sensor, for data gathering at source • - data logging equipment, for local site storage • - a communication system, for transferring data to the operator • - software, for archiving and presenting data Sensors A typical monitoring system will include sensor capacity and interface leads for a range of DMA meters and pressure monitors; • - digital and analogue (e.g. 4-20mA, 0-1V) output • - specific pulse heads for helix meters (e.g Kent PD100 pulse disk bidirectional sensor) • - other proprietary sensors (HRP, LRP, reed switch, BPG20) • - optical sensors • - magnetic sensors • - pressure and depth transducers Data Capture Data capture requires the use of pulse generators, pulse counters and data loggers (portable or with telemetry) to capture data from the DMA meter.
