Introduction and general information
The Hydro-Logic®Flexi Logger 105 is a telemetry data logger. It takes
measurements from single or multi-parameter sensors at regular intervals
(typically every 5 or 15 minutes) and stores this data in internal memory. Using a
mobile data modem, the Hydro-Logic®Flexi Logger 105 contacts a telemetry
server (typically once per day) and transfers data to it.
Main features of the Hydro-Logic®Flexi Logger 105
The main external features of the logger are shown below. (1) Serial number
window. There is only one serial number. (2) Status LED and magnet switch
location. (3) GORE® breather for sensor connector. (4) External antenna
connector. There is also an internal antenna. Switching is automatic. (5)
Ventilated sensor connector. (6) Wired comms and external power connector.
