<strong>2150EX</strong> Area Velocity <strong>Flow</strong> System<br />
Section 1 Introduction<br />
1.1 Product Description The <strong>2150EX</strong> Area Velocity <strong>Flow</strong> <strong>Module</strong> is part of <strong>Isco</strong>’s 2100<br />
Series. The 2100 Series measures parameters of open channel<br />
flow streams.<br />
The intrinsically safe <strong>2150EX</strong> is intended for use in potentially<br />
explosive atmospheres, and complies with ATEX Directive<br />
94/9/EC. The <strong>2150EX</strong> is Group II, Category 1G or 2G equipment<br />
as appropriate for use in Hazardous Zones 0, 1, and 2.<br />
The purpose of intrinsic safety is to limit the energy available to<br />
a given circuit or device to a level where electrical discharge<br />
(sparking) cannot ignite the hazardous (flammable or explosive)<br />
atmosphere. With no spark ignition possible, safe operation of<br />
the equipment in areas with potentially explosive atmospheres is<br />
possible.<br />
The standard 2100 Series is designed to be modular so that you<br />
can expand the system by stacking modules to meet your data<br />
collection needs. The <strong>2150EX</strong> incorporates this modularity,<br />
allowing up to two <strong>2150EX</strong> modules to be stacked on one 2191EX<br />
or 2196EX battery module.<br />
The <strong>2150EX</strong> is paired with <strong>Isco</strong>’s <strong>Flow</strong>link software. With this<br />
full-featured application software, you can quickly set up the<br />
module, retrieve measurement data, manage the sites, and<br />
analyze the data, and update the module’s own software, all<br />
without entering the hazardous area.<br />
The module’s data storage memory is quite flexible, able to store<br />
the measurements in intervals from 15 seconds to 24 hours. The<br />
module can also be configured for variable rate data storage.<br />
Variable rates allow you to store data at a different interval<br />
when a programmed condition occurs.<br />
The module’s program and collected data are stored in flash<br />
memory for security. Flash memory retains data without the<br />
concern of power failures or aging backup batteries. Its capacity<br />
is more than sufficient for most applications. The data storage<br />
memory can hold approximately 79,000 readings – the equivalent<br />
of nine months of level and velocity data when stored at<br />
fifteen minute intervals. The flash memory also stores sensor<br />
level adjustment information. A separate flash memory device<br />
inside the module stores the operating firmware.<br />
The rugged <strong>2150EX</strong> components are rated NEMA 4X, 6P (IP68).<br />
The permanently sealed enclosures are designed to meet the<br />
environmental demands of many sewer flow monitoring applications.<br />
All connections between sensors and communication cables<br />
“lock” in place. Each locking mechanism strongly secures the<br />
components and ensures a watertight seal.<br />
