Sewer network monitoring in Athens

摘要

Water and asset monitoring specialist HWM has added GPRS data transmission to its Pressure Transient Logger. The logger triggers a capture window around a transient event and transmits this data. Operators can send transient alarm information and a selectable window of fast logged data before and after an event via an event window selection feature. The sampling rate on the logger's pressure transient channel extends to 100 times a second and operators can define sampling intervals and transient data capture trigger levels.
