Catalog excerpts
The 2150EX is an intrinsically safe Area Velocity Flow Meter which has been approved by Baseefa and CSA for use in potentially explosive atmospheres. The AV 2150EX smart Area Velocity probe is built on digital electronics, so the analog level is digitized in the sensor itself. The probe is also factory-calibrated for temperature and 3-meter span. This built-in calibration data eliminates temperature drift in the level signal, providing long-term level stability that reduces recalibration frequency and completely eliminates span recalibration. Superior Probe Design All-digital electronics Built-in microprocessor eliminates EMI interference No temperature drift No span calibration required Long-term level stability Field interchangable Power Options Battery Module 2196EX with built-in lead-acid rechargeable batteries (for Zone 1 or Class I Division 1 applications only). Rechargeable lead-acid batteries Lithium batteries 2194EX Network Interface Module Applications Open channel flow measurement in hazardous locations Portable and permanent-site AV flow monitoring for inflow and infiltration, sewer overflow, and other sewer studies. Measuring shallow flows in small pipes. The low-profile Area Velocity sensor minimizes flow stream obstruction and senses velocity in flows down to 25 mm in depth. Level measurement in potentially explosive areas such as manholes, digesters, and storage tanks. Standard Features Rugged, submersible enclosure meets IP68 (NEMA 4X, 6P) environmental protection. Chemically resistant epoxy-encapsulated sensor withstands abuse, resists oil and grease fouling, and eliminates frequent cleaning. Replaceable high-capacity internal desiccant cartridge and hydrophobic filter protect sensor reference from moisture and water entry. Pressure transducer vent system automatically compensates for atmospheric pressure changes to maintain accuracy. RS232EX Isolator Cable provides safe, inthe- field connection to a laptop computer. The quick-connect sensor can be easily removed and interchanged in the field without needing recalibration. 2150EX Intrinsically Safe Area Velocity Flow System The 2150EX is approved to the ATEX Directive 94/9/EC by Baseefa, and to Class I, Division 1 by CSA for use in manholes and other hazardous locations. A second flow module can be stacked to provide redundant or multistream measurement.
Open the catalog to page 1Variable rate data storage The 2150EX flow module has the ability to automatically switch data storage rates based on varying conditions. In the example at left, the 5-minute data storage rate automatically changed to 30 seconds when the flow rose above a programmed level. Software Features Secure data storage. All data are continuously stored in "flash" memory to protect against loss in case of power failure Easy to upgrade. New operating software can be downloaded into non-volatile "flash" memory, without affecting stored program and data, and without removing the 2150EX from the...
Open the catalog to page 2Portable installation For temporary installations, the 2150EX with battery module is suspended in a manhole or other hazardous area. The EX network cable is routed to the safe area, where it can be connected via a second cable to a laptop computer running Isco Flowlink® software. This allows data retrieval and setup without removing the flow meter from the manhole. Flowlink® data analysis Isco Flowlink® software is a powerful tool for analyzing flow and water quality data. This screen shows a comparison of dry and wet weather flows, plus rainfall, typical of an Inflow & Infiltration study....
