Logger for monitoring the operating pressure of natural gas

EP-LOG is a DataLogger designed to monitor the operating pressure in low pressure natural gas distribution networks (UNI/TR 11631:2016 standard).


EP-LOG can connect to the SCADA centre in several ways including: GSM/GPRS, UMTS, LTE, SMS, Radio Modem-169MHz, NB-IoT, LoraWAN. EP-LOG can be configured and updated both locally and remotely in order to adapt its behav- iour to changing regulations.


EP-LOG can be installed on pole or wall mounted boxes and can be supplied with a pressure cable for underground gas outlets or with a connection for off-road gas outlets, guaranteeing maximum installation flexibility..

 

FUNCTIONS

The data that the EP-LOG makes available includes:

  • Pressure
  • Temperature
  • Time intervals with out-of-threshold pressure
  • Out-of-threshold temperature indication
  • Real-time communication for a limited period of time

 

CENTRE - SCADA

The SCADA collects data from all EP-LOGs and calculates the following parameters:

  • Plant efficiency parameter (Peff) Minimum pressure
  • Maximum pressure
  • Average pressure
  • Average squared deviation Out-of-threshold pressure time

 


EP-LOG is ATEX certified and can be installed in potentially explosive areas.
The battery life exceeds 5 years with standard GSM/GPRS communications, i.e. by communi- cating the daily historic data to the SCADA once a day. In the event of an alarm, immediate com- munication with the SCADA itself is activated. The batteries are housed in such a way that they can be easily replaced.
