Hardware configuration and installation

Device overview

Refer to the block diagram below. The Hydro-Logic

®

Flexi Logger 300Ex is

controlled by a low-power microcontroller. There is a sensor interface with HART
modem, 3 sensor connectors and storage on local memory for the logger
configuration and typically several months of time-series data.

A 3G mobile data modem is used to transfer data to a remote data collection
system via either an internal and or external antenna. The modem includes a
standard SIM interface.

The orange lines show the power distribution. There is an internal battery which
can typically provide years of operation. The HLC is a small module containing a
rechargeable battery which provides boost power for the modem and sensor as
required.

Yellow zones in the diagram are ATEX components or subsystems designed to
allow safe operation in explosive atmospheres. See
