SePem 01

Stationary noise logger for early leak detection in water supply networks

The amount of water lost through leakages in the water supply network largely depends on how long it has been leaking from the damaged spot. Reducing the quantities of water lost thus means minimising the duration of the leak. Besides conventional methods of systematic leak detection in evolved network structures, the SePem® 01 stationary noise logger offers a practical alternative for permanently monitoring areas which have already been declared leak-free. The SePem® 01 loggers are positioned in valves inside the measuring area. They can, of course, also be fitted to fire hydrants. The instruments record sounds in a defined measurement cycle and emit signals at a certain radio time. These are then transmitted out of the valve box by radio. The signals are received by the SePem® 01 - Master, which collects the data when driving past. The loggers do not have to be removed from their measuring positions, nor do the covers have to be opened.


  • Large radio range
  • Can be installed vertically or horizontally
  • Flexible measuring and transmission times
  • Flexible antenna positioning in the measuring points
  • Long battery life
