3.3 billion litres of water are lost through leaking pipes each day in the UK. As a result, water authorities face increasing demand to find innovative ways to monitor water flow within pipes. Currently, GSM data loggers are used to monitor water flow wirelessly and improve the efficiency of dealing with leaks. The big problem with GSM loggers is they use a network specific SIM, which means different SIMs are required for different locations due to network coverage.
