Description
The LL-GAUGE-010 is a 10m water level and temperature logger designed for long-term deployment in diverse aquatic environments, including harsh and saline conditions, thanks to its durable all-Titanium body and comes backed by a 5-year warranty. It precisely measures water levels up to 10m with a 5cm accuracy. A sealed option is also available, LL-ABS-010.
The LL-GAUGE-010 connects via the Vented Leveline Extension Cables to surface, where connection via the LL-EXT-TEL-AD and EX-TDH allows for desiccant to prevent water ingress. The vented cable is necessary to allow readings to be compensated for atmospheric pressure and allow for data to be retrieved from the loggers, or to use as a simple Modbus or SDI-12 sensors. The integrated data logger is capable of storing 500,000 data points and powered by a 10-year lithium battery. The whole unit is housed within a 22mm x 186mm all-Titanium body, ensuring resilience in demanding environments. The device is supported by Levelink PC software for data processing and carries a 5-year warranty. The device can be easily deployed using the Leveline QuickDeploy Key.
