New unit offers cost-effective data transmission and prolonged battery life
HWM has added GPRS data transmission to its pressure transient logging capability. The new GPRS Pressure Transient Logger triggers a capture window around a transient event and transmits this data, keeping costs down and prolonging battery life.
The ‘event window selection’ feature allows operators to send transient alarm information and a selectable window of fast logged data before and after the event. Network transient monitoring is now feasible via remote telemetry rather than manual site surveys. As transients are immediately identified, swift remedial action can be taken to avoid burst and infrastructure damage.
Specifically designed to combat water hammer, the data logger features sampling rates up to 100 times per second to effectively monitor for damaging pressure spikes, which may only last a fraction of a second. Addressing these brief moments of extreme pressure is a major factor in reducing burst water mains. Now that data is immediately available through remote telemetry, swift remedial action can be taken to avoid infrastructure damage.
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. With the optional addition of flow channels, the unit is able to provide comprehensive transient and general network monitoring.
Supplied in an IP68-rated case, the logger is designed for long-term field deployment. Its 4GB flash memory (SD card) offers storage for up to eight billion readings. Typical battery life is two years with internal batteries at a sampling rate of 25 Hz, one data connection per day and typical event window dial-ins. External HWM battery packs can be added to support more frequent sampling or dial-in rates, or to extend life between battery changes.
