Phocus.hr Remote leak detection via AMR radio system Primayer technology for network management and leakage control Operation Phocus.hr is an intelligent noise logger which detects the noise generated by a water leak. The logger samples the pipeline noise at one second intervals during each of three periods during the night. Night-time is when the background acoustic noise is lowest. Phocus.hr makes a statistical analysis during each of the three periods to determine the Leakage Confidence Factor LCF or ‘leak alarm’ status. The logger transmits a daily radio message. The message includes the LCF and the level of the lowest measured noise called the Critical Noise Value. This value is important because it determines the proximity of the leak from the Phocus.hr logger. Features • Transmission of daily information • Three different sample periods overnight separate genuine water use from leakage to reduce false alarms • Uses Phocus noise algorithm for better detection of leaks • Significantly reduced operating costs as no ‘drive-by’ required • Integrates with the AMR radio network HOMERIDER SYSTEMS to reduce system costs • Interfaced with the Veolia software LERNE for optimum use of data Phocus.hr is a variant of the Primayer Phocus range of noise logger. It transmits data via the AMR radio network of HOMERIDER SYSTEMS. It is designed to detect and localise leaks in water distribution networks under pressure. Phocus.hr is permanently installed on the network and automatically determines the presence of leaks.

The operator can define the minimum threshold level of leak noise over which an alarm condition will occur. The daily transmitted data is integrated directly under the host software platform LERNE. The user can access all information including signature of leak noise Critical Noise Value and Leakage Confidence Factor. Noise histogram The leakage status data is stored in LERNE
