Live Measurement Data Acquisition SYSTEM

Live Measurement Data Acquisition System (LiMeDAS) is a powerful and robust software application package designed to collect, store, display and report industrial process-related data from a variety of sources.

LiMeDAS is a highly customizable solution that can be easily extended to monitor virtually any process be it a gas analyzer measuring effluent emissions, a custody transfer gas flowmeter, or a fire alarm sensor.

Main Screen

Our software is designed to monitor various processes on an intermittent or continuous basis. We have a range of off-the-shelf solutions to help with data collection, visualization, analysis and reporting for most common applications where industrial process monitoring is involved.

The collected process data from each source is permanently stored in the corresponding database. The central server will allow the user to view the data individually or compare it side by side.

Data Collection Unit

The Data Collection Unit (DCU) software product is designed to run and collect data on a continuous basis. It can be located close to the data measurement point such as a shelter cabinet or device control panel to directly interface analyzer(s).

The DCU features a touch-screen friendly graphical interface that can be used to observe collected data, see the real-time data updates, and check device status and diagnostics information.

The DCU can connect to one or many devices simultaneously using Ethernet or Serial network, and can be used to interface various devices such as gas analyzers, temperature and pressure meters, and dust and flow monitors.

The DCU can interface with any Modbus or OPC capable third party software component or hardware device such as analyzer, analog or digital I/O module, Data Logger or OPC Server software, and plant DCS system for data acquisition and value exchange. The DCU can be configured to be a Modbus Master or Slave, as well as an OPC Server or Client.

DCU Main


Limesoft Inc. develops two main products used for data acquisition and analysis.


  • The application is available in multiple languages and is regional settings friendly.
  • Distributed architecture allows monitoring data sources from multiple Network locations.
  • There is no pre-defined user interface. Users are able to have their own data displays.
  • User authentication and security is based on Windows User Management. LiMeDAS keeps all data safe and secure and provides custom user access levels.
  • Powerful reporting engine is designed to support multiple languages and is fully customizable.
  • Robust and scalable client-server architecture allows simultaneous client access from Desktop and Mobile clients.
  • DCU

  • The application can run within an industrial panel PC, featuring a touch-screen capable friendly user interface.
  • DCU can communicate to the plant DCS and exchange data with process data historian applications.
  • It is possible to interface a wide range of analysers and measurement equipment using Modbus and OPC communication protocols.
  • DCU stores data simultaneously into two databases to ensure high data availability and automatic data synchronization and replication.
  • All collected data is stored permanently.
