Thiết bị ghi dữ liệu MULTILOG LX 2 HWM Water
INNOVATIVE FAST LOGGING
The LX 2’s innovative secondary channel feature enables additional fast logging up to 25Hz. This is invaluable when more detailed investigation is required, such as transient pressure spikes and ‘true’ minimum night flow. Previously, fast logging could only be used as a manual direct download but faster GPRS data transfer rates and reduced costs have enabled HWM to make this a telemetry feature. The standard logging continues alongside the fast channel logging for general reporting purposes. Fast logging can be triggered from a time window or alarm threshold.
EXTENSIVE BATTERY LIFE
Replaceable internal batteries can power the logger for over five years when data is transmitted every 12 hours. A range of low cost external battery packs are available which maintains the five year battery life when sending data every hour, 30 minutes or 15 minutes.
