RM-WL
Leakage Monitoring and Fault Localisation in Pipe Systems
The LANCIER Monitoring Rail-Module-Bus is a modular and robust sensor system.
Several measuring modules are mounted on a DIN rail and are directly connected to one another by means of plug-in contacts. The supply voltage, data analysis and control panel as well as their transmission to the remote measuring stations are carried out via the RM-Basic module.
he 2-channel RM-WL monitoring module for measuring insulation and loop resistances, in order to detect and locate leaks in pipe systems and rooms, monitors the insulation and loop resistance of a 4-wire WLC leak warning cable.
The leak warning cable is positioned below horizontal fluid-conducting pipes, if necessary inside an insulation layer, wrapped around vertical pipes or installed in regular loops in room floors. In this way, it can detect leakages of electrically conductive fluids, e.g. water, acids and alkalis.
The WLC cable is measured continuously by the RM-WL module. Threshold values for both the loop and insulation resistance can be adjusted locally via the built-in keys and shown on the display of the basic module. Alongside the settings current measured values are of course also displayed.
Furthermore, the RM-WL module recognises and reports line interruptions.
For remote alarms RM modules are fitted with potential-free alarm contacts. Beyond that they can be integrated into telecontrol systems or the LANCIER UMS monitoring system via a range of interfaces.
Furthermore, the use of the LANCIER UMS software makes it possible to display the pipe network’s status and to represent it in a geographical information system.
