The Sewerin SePem 155 radio noise loggers are the latest in Sewerin noise logger technology. The SePem 155's offer class leading construction and performance. Their stainless steel and durable plastic construction meet IP68 standards. They are completely waterproof and resistant to all corrosion making them suitable for all water distribution environments. SePem 155 loggers utilize long life batteries (many years) and class leading sensitive Piezo microphones specifically optimized for water leak detection. SePem 155 loggers can be deployed in both the traditional "Lift & Shift" applications or on a semi-permanent "Patrol" application via attaching them to valves, pipe or fittings using their powerful magnets and listening for leaks during off hours like between 2:00am-4:00am. SePem 155 loggers are programmed by the SePem 01 Master controller. The SePem 01 Master controller is a hand-held device that can also be mounted into a vehicle bracket for "Patrol" applications. During "Patrol" or drive-by the SePem 01 Master controller will automatically communicate with the SePem 155 loggers as they come into range of its bidirectional radio and indicate both via audible tone and visual display a leak indicated or no leak found. Information such as "Minimum noise level" and "Noise consistency" will be highlighted on the display for easy user analysis. Loggers that record no leak noise will simply indicate zero. Each SePem 01 Master controller can accommodate up to 500 SePem 155 loggers.
