Versatile virtual flow computer software

Precise, our virtual flow computer solution, is a software product based on proven TruST technology. It is designed to replicate the functionality of a traditional flow computer without the need for separate flow computing hardware.

Precise operates to fiscal standards, which means it can be used as a flow computer replacement and it is particularly cost effective on multi-stream allocation systems. The software can acquire and display data from almost any device in the metering environment, applying alarming, reporting and eventing to each device.

It can also pull together multiple streams, allowing the user to create custom metering stations.
Because Precise is based on our TruST system, as well as industry standard calculations it offers custom programmable areas, allowing users to configure specialist calculations to meet their system requirements.

The software uses an IEC-61131-3 configuration environment and can attach to any Modbus enabled I/O, typically Programmable Logic Controllers (PLC), Distribution Control Systems (DCS) and other commercially available hardware.

The benefits Precise offers include:

  • Accuracy: The software was developed to meet demand for high accuracy fiscal measurement at a low cost
  • Value: Precise eliminates the need for traditional flow computing hardware
  • Versatility: The software can be used to create a custom designed metering environment, incorporating all aspects of the metering system
  • Flexibility: Precise can attach to almost any commercially available hardware
  • Ease of use: The ST103A is a low power device that is easily fitted onto an existing Din rail in a panel
  • High performance: The ST103A is suitable for use across a wide temperature range, making it ideal for use in the field, within a relevant enclosure
High accuracy flow monitoring

High accuracy flow monitoring

To meet customer demand for high accuracy measurement we developed the ST103A module, a data acquisition unit designed to meet the specific demands of fiscal metering without the expense associated with traditional flow computers.

As well as being rich in traditional I/O, this module features a highly accurate clock. Precise uses a special integration technique, continually calibrating the PC’s clock ‘tick’ accuracy against the stable clock of the ST103A source. It reads and updates all I/O within 500 milliseconds, and makes the data available over two Modbus serial ports.

The main Precise computing software can be installed on a standard desktop PC or server. Hardware I/O signals are brought in through the ST103A module. Read more about ST103 and ST103A here.

The Precise software module can be supplied as part of our established TruST metering software package. Contact us to find out more.
