Zero power modems help relieve leaks

Multilog dataloggers from Radcom Technologies use Telemodem 2 technology, allowing users to call up extended networks remotely to a central location for instant monitoring of pressure and water flow.
Water leaks are extremely costly.
It is estimated that water authorities lose 30% of their treated water to leaks.
To help the industry address this problem, a leading UK company has now integrated the latest 'zero power' Telemodem 2 modem technology from Jekyll into its battery powered waterproof dataloggers for fast remote access to water monitoring data.
One of the main difficulties with water leakage is detecting problems early, and pinpointing the exact position of leaks.
Daytime interferences and a general lack of skilled operators also add to the problem.
With the new Multilog dataloggers from Radcom Technologies, users are able to call up extended networks remotely to a central location for instant monitoring of pressure and water flow at selected sites and identification of leaks.
This increases the efficiency of water management programmes, and saves on unnecessary on-site visits.
Battery life is critical in these remote monitors and any additional battery load presented by the communications function is unwelcome.
The Telemodem 2, selected by Radcom for the Multilog, offers 'zero power' operation and therefore gives no additional drain on the logger's battery to maximise capacity and hence extend maintenance free life.
The Telemodem2 is easy to install, either at system design or as a retrofit, with built-in mounting lugs or the option of DIN carrier rail fixing.
The Freedom unit inside the Radcom multilogger includes a reliable data transfer up to 2400bit/s.
Remote setup and diagnostics for online maintenance, an industry standard 25-way D dataport connector, and CTR/21 compliance for use throughout Europe and beyond also feature.
Built to withstand harsh industrial conditions, the Telemodem 2 allows remote data collection from any equipment where a V24 dataport is available.
Units range from the low power Standard for basic remote communications, to the novel 'zero power' Freedom that draws all its power direct from the telephone line, through to the new high performance Fastlink for fast access to larger amounts of data.
Even optical data ports and intrinsically safe interfaces have been provided where required.
