Problem

DLR have 18 Crowcon gas detection units across the network, monitoring alarms for Methane and Hydrogen Sulphide.  Each monitoring unit is connected to SCADA which relays when alarm limits have been exceeded, there is no real time monitoring to show current gas levels. The obtain current values requires a site visit to manually record the values shown on the Crowcon  display.  

Solution

To monitor in real-time the Methane and Hydrogen Sulphide gas levels, feeding data to any web enabled device.

Our data harvester connects into the Modbus connections on the Crowcon control unit.  We take values and alarm status every 10 seconds, which if fed direct out our servers.

This is an example of where of we take data that is already available and provide the client with analytics and a graphic display,    allowing informed business decisions to be taken that are data driven.
