VuLink Data Logger and Telemetry
VULINK CELLULAR (CI) AND VULINK SATELLITE (SI) ARE
GLOBAL TELEMETRY DEVICES THAT WILL CHANGE THE WAY
YOU THINK ABOUT REMOTE MONITORING. OUR TURNKEY
SOLUTION IS EASY TO SET UP, WORKS FROM ANYWHERE,AND DELIVERS LONG-LASTING POWER. SO, YOU NEVER HAVETO WORRY ABOUT YOUR EQUIPMENT OR YOUR DATA.

EXTENDED LIFE
• VuLink offers two-to-five times the battery life of similar devices.
M1 and NB-IoT offer extraordinary power savings. And at fasterreporting rates, VuLink offers exponential savings – more than
two years of battery life at 15-minute reporting intervals.
• Say good-bye to custom, expensive batteries – VuLink uses
off-the-shelf alkaline and lithium D cell batteries.

ONE-PRESS SETUP• VuLink autodetects any In-Situ device with one button press orscheduled report. Icons indicate battery life, instrument connection,
network connection and HydroVu connection.
EXPANDED COVERAGE• VuLink Cellular (CI) is truly global, offering cellular coverage acrossmultiple networks. Future proof your system for decades with 4GLTE Category M1/NB-IoT technology, while ensuring backwards
compatibility with quad-band 2G coverage.
• VuLink Satellite (SI) is the first in-well Iridium satellite device
featuring customized data compression and low power usage tolengthen battery replacement cycles.
FREE GLOBAL CELLULAR DATA
• VuLink offers free cellular data for life, right out of the box,
no set up required. See back for details.
