This module is placed if water consumption must also be measured and monitored in the sanitary blocks. The entire MBV-MONI-SAVER system consists of a special MBV-SAVER lock valve, a water meter with pulse, a leak detection kit AS-LEAK (to detect continuous leaks) and an electronic module SANIMOD-DIN. The electronic module controls the tap, records the water consumption and also the alarms of the leak detection kit, and prepares all consumption data and alarms in Modbusregisters so that a very easy connection to the building management system (BMS) can are realized. It is a module with web server for monitoring data and remote alarms. By placing this system, one obtains the necessary BREEAM points.
