1.2 Product Description The 2103 Modem is a portable data interrogation unit designed
to transmit data from Isco’s 2100 Series flow modules, which
measure parameters of open channel flow streams. It works in
conjunction with Isco’s Flowlink software.
The 2103 Modem can be located anywhere within a stack of up to
three other 2100 Series networked modules, using the same
locking mechanism that connects the 2100 Series modules to
each other. The 2103 is compatible with Isco’s 2150 Area Velocity
flow module, 2110 Ultrasonic flow module, 2101 Field Wizard,
and 2102 wireless module. It is powered by Isco’s 2191 battery
module.
All enclosures are rated NEMA 4X, 6P(IP68). The permanently
sealed enclosures are designed to meet the environmental
demands of many sewer flow monitoring applications. All connec-
tions between modules, sensors, and communication cables lock
in place. The locking mechanisms strongly secure the compo-
nents and ensure a watertight seal.
