Integrated Flow metering in Depot & Terminal Automation

Flow metering within the concept of Depot and Terminal Automation with eXLerate can be an integral part of the depot and tank management system.

 

tabat 4Interfaces with flow computers and field equipment from various manufacturers is realized by means of its communications drivers, ranging from Ethernet or serial port based Modbus RTU/ASCII, Master & Slave, HART®, to various vendor specific communication protocols.

 

Supported metering devices

Special metering devices, such as ultrasonic meters, electronic turbine meters and flow computers from various vendors are integrated in eXLerate beyond the regular Modbus interface found in many other metering systems.

For example, eXLerate is able to directly read out historical reports from various brands of flow computers which are archived and can be reprinted at any time.


A sophisticated mechanism make sure that the central report archive is synchronized with all the flow computers at all times even when the eXLerate system has been offline for a longer period of time.

Liquid metering functions

Liquid (and also gas) metering are areas in which eXLerate is powerful through its available metering functionality.

The support for liquid metering includes, but is not limited to:

  • Liquid density calculations (i.e. API liquid density calculations, TP-25 LPG density corrections and various other liquids) ready to be directly used in the application spreadsheet.

  • Retentive flow totalizers, time weighted averages, flow weighted averages and periodic time series for each data point as required.

  • Linearization curves for correction of calibrated meters straight in the application software.

  • Proving (master meter proving, compact and ball proving) either through a flow computer or directly in the application.

  • Batching, batch control, and associated batch reporting.

  • Instrument validation & diagnostics (on-line and real-time verification of field instrumentation, such as pressure transmitters, temperature transmitters, densitometers etc).

  • Audit trails at the supervisory level, as well as from connected devices.

  • All of the required flow metering equipment specific data formats (i.e. 64-bits IEEE double precision floating point formats, various dedicated formats).

  • Ultrasonic meter diagnostics & validation (VOS footprint charts, VOS ratio chart, gain monitoring, status monitoring).
