2150EX Area Velocity Flow System 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 configured for variable rate data storage. Variable rates allow you to store data at a different interval when a programmed condition occurs. The module’s program and collected data are stored in flash memory for security. Flash memory retains data without the concern of power failures or aging backup batteries. Its capacity is more than sufficient for most applications. The data storage memory can hold approximately 79,000 readings – the equivalent of nine months of level and velocity data when stored at fifteen minute intervals. The flash memory also stores sensor level adjustment information. A separate flash memory device inside the module stores the operating firmware. The rugged 2150EX components are rated NEMA 4X, 6P (IP68). The permanently sealed enclosures are designed to meet the environmental demands of many sewer flow monitoring applications. All connections between sensors and communication cables “lock” in place. Each locking mechanism strongly secures the components and ensures a watertight seal. 1-1
