GPS Communications Ensure an Accurate Clock

The Delphin LogMessage is a stand-alone operating device for acquiring, monitoring, calculating and logging measurement data. It is equipped with a 3.5GB memory for logging up to 250 million measurement values. Recently a Spanish oil & gas consulting company, Sumelco Technologies, is proposing to use these data acquisition systems for remote data collection. CAS DataLoggers briefly outlines the requirements and features in the following Apps Note.

What Sumelco Does:

Remote Control: Automation

  • Gas
  • Electricity

Gas Pipeline Pressure Control by GPS:

Oil & Gas companies’ interstate pipeline networks and systems extends for hundreds of kilometers across the world. This target project is the latest in an ongoing industry effort to control gas leakages across the main pipeline networks.

Sumelco’s proposal incorporates the Delphin LogMessage series dataloggers. The LogMessage's analog inputs are differentially and galavanically isolated from each other as well as from the power supply. Earth loops and non-isolated sensors therefore present no problem. All analog inputs can be used universally and are capable of measuring any type of thermocouple, RTD, voltage or current signal. Channel configuration takes place via the easy to use DataService Configurator software included with the delivery.

Data Logger Requirements:

  • High Speed 4-20mA data acquisition for online pressure reading
  • Datalogging with high memory capacity 4GB
  • Autonomous datalogger. NO PC connected!
  • Filtering functions: low pass filter
  • GPS clock update and position
  • External communications with dataloggers and memory recorded by Delphin’s dll. Customer is developing a .NET solution with the API.


Once configured, the Delphin LogMessage can operate standalone and requires no PC support. Configuration and data readout takes place via a network interface. LogMessage's two serial ports enable connection of a modem for remote access, or for other hardware to be connected for data transfer purposes. Alarm notifications and text messages may also be transmitted using a GSM modem. By operating the LogMessage device within a network, measurement data can be transmitted online and processed using the ProfiSignal Go software.

Filtering mA Input with Calculation Channels:

  • S0 = X0
  • S1 = a*X1 + (1-a)*S0
  • S2 = a*X2 + (1-a)*S1



LogMessage devices are supplied with the powerful ProfiSignal Go software. ProfiSignal Go is a professional PC software for the online and offline monitoring and analysis of measurement data. If you already use other measurement technology software, the full service package includes LabVIEW™ and DASYLab™ drivers, Modbus TCP and OPC Server.
