Communication 4-5
Installing the GSM Module
Establishing remote, wireless communications with the battery-
powered FlowHawk monitor involves installing a GSM module in
the manhole.
The GSM Module (p/n 8000-0052) is a polycarbonate enclosure
containing an electronic assembly comprised of a modem module
and intrinsically safe isolation components. The enclosure has a
clear, removable top to allow the user to access the SIM card
holder. The module also contains an LED window visible through
the clear cover that displays monitor activity and diagnostic codes.
Each module bears an IS Certification label, as well as the serial
number of the unit. A cable, exiting one side of the module,
connects to the monitor communication port. A female SMA
connector located on the other side exists for connecting an antenna.

test the FlowHawk and GSM module with the SIM card
installed to verify the entire system functions and confirm
