Water leakages in pipes, fittings or systems, e.g. in server rooms, computer centres, air conditioning and heating centers as well as archives and libraries, can cause considerable damage to buildings and their inventory and equipment. Gradual damage caused by leaks, occuring over a long period of time, can only be eliminated with great effort and high costs, as the pipes are often installed in double floors, suspended ceilings or hollow wall construction.

To avoid these costs, METZ CONNECT offers a new leakage/level sensor MR-LD6, which can be quickly and conveniently integrated into the building control system via the Modbus RTU protocol or used independently without a control center. The leakage/ level sensor MR-LD6 monitors and locates leakage points caused, for example, by a pipe rupture, using an electrically conductive liquid. The MR-LD6 functions by measuring the resistance of the conductive liquid. In addition, immersion electrodes (e.g. TE1) can be used to monitor levels in containers such as wells or cisterns.

Two integrated relay outputs are used to switch magnetic valves and pumps or to signal a pipe rupture. A cable break is detected and signalled by the MR-LD6 (suitable sensors required, e.g. LKS-ZD). The MR-LD6 can be configured for different applications using MR-CT software from METZ CONNECT. In this way, for example, a level with three immersion electrodes and four chambers can be monitored for leakage, or, for example, six chambers can be monitored for leakage and/or other line-ups.
