10. Section 1 Introduction 1 1 Product Description The 2150EX Area Velocity Flow Module is part of Isco s 2100 Series The 2100 Series measures parameters of open channel flow streams The intrinsically safe 2150EX is intended for use in potentially explosive atmospheres and complies with ATEX Directive 94 9 EC The 2150EX is Group II Category 1G or 2G equipment as appropriate for use in Hazardous Zones 0 1 and 2 The purpose of intrinsic safety is to limit the energy available to a given circuit or device to a level where electrical discharge sparking cannot ignite the hazardous flammable or explosive atmosphere With no spark ignition possible safe operation of the equipment in areas with potentially explosive atmospheres is possible The standard 2100 Series is designed to be modular so that you can expand the system by stacking modules to meet your data collection needs The 2150EX incorporates this modularity allowing up to two 2150EX modules to be stacked on one 2191EX or 2196EX battery module The 2150EX is paired with Isco s Flowlink software With this full featured application software you can quickly set up the module retrieve measurement data manage the sites and analyze the data and update the module s own software all without entering the hazardous area The module s data storage memory is quite flexible able to store the measurements in intervals from 15 seconds to 24 hours The module can also be

25. Flow Module Section 1 Introduction Circuits internal to the module compare the frequencies of the sound waves and extract the difference An increase or decrease in the frequency of the reflected wave indicates forward or reverse flow The degree of change is proportional to the velocity of the flow stream Using measurements from the AV Sensor the 2150EX can cal culate the flow rate Many different flow rate conversion methods are supported Area Velocity Data Points Manning Formula Two term Polynomial Equations Flumes Weirs Often the 2150EX is chosen for applications where a primary device is not available nor is it practical to install a primary device Therefore area velocity is usually the conversion method of choice The 2150EX is capable of calculating and storing any two con version methods simultaneously This feature is useful when it is necessary to validate a flow conversion method For example the flow rate at a new site programmed for area velocity conversion can be directly compared to the flow rate calculated using a Manning formula The 2150EX can calculate and report the total flow You can set up the system to monitor net positive or negative total flow from either of the calculated flow rates Through Flowlink you configure which type of data is logged and the storage rate For each measurement the Data Storage Setup window lets you turn the primary rate off or select a rate from 15 seconds to o
