MultiLog GPRS
Multilog is the proven Radcom multi-channel hardware platform with thousands of units installed worldwide. It has now been upgraded to include the benefits of advances in GPRS availability, and cost effective commercial rates.
MultiLog GPRS has up to four inputs for monitoring any combination of digital or analogue signals, and features an innovative ‘secondary channel’ feature which enables an additional fast logging channel that can log down to one second intervals. This is invaluable when more detailed investigation (such as pressure spikes and ‘true’ minimum night flow) is required. The pseudo channel trace can be implemented to track max or min of the fast logging results. Previously, secondary channel logging could only be used as a manual direct download but lower GPRS data transfer rates have enabled HWM to make this available as a telemetry feature. The standard logging continues alongside the more intense logging for general reporting purposes.
Low power electronics enable the long battery life to be maintained even with increased transmission rates. The replaceable internal batteries will typically power the device for over five years when data is transmitted every eight hours. Three options of low cost external battery packs are available which enables this typical five year life to be maintained when transmitting data every hour, 30 minutes or even down to every 15 minutes.
Can be used to perform dynamic flow & pressure analysis of network models, particularly where hourly data updates can be useful for near real time monitoring.
