Water/Wastewater 47 New Intrinsically Safe Area-Velocity Flowmeter
The new Isco 2150EX Flowmeter is the intrinsically safe version of Isco's (USA) modular Area-Velocity flow system. The 2150EX is designed and Baseefa- approved for use in potentially Explosive Atmospheres (category 1G) under the ATEX Directive 94/9/EC. Powered by two Lithium batteries, the 2150EX uses highly efficient power management to achieve battery life up to 9 months with two-minute data storage interval. Rechargeable batteries and an AC-powered Network Interface Module provide great flexibility for a variety of long-and short-term monitoring applications. Isco's exclusive variable rate data storage enables programmable changes in the data interval, to further extend battery life and provide more detailed data only during unusual flow events.
Area velocity flow measurement provides greater accuracy in open-channel applications where weirs and flumes are not practical, and where submerged, full pipe, surcharged, and reverse flow conditions may occur. Applications for the 2150EX flowmeter include: Portable and permanent-site AV flow monitoring for inflow/infiltration, sewer overflow, and other sewer studies; Measuring shallow flows in small pipes. The low-profile Area Velocity sensor minimises 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. The 2150EX stores data continuously in "flash" memory to protect against loss in case of power failure. Isco's versatile Flowlink®
Software provides site setup as well as retrieval and analysis of stored data. Reader Reply Card no 164
Dates Announced for WWEM 2010 - the World's Largest Water Monitoring Event
ANALYTICAL INSTRUMENTS
Turbidity Measurement AMI Turbiwell
for the measurement of turbidity in potable water, surface water and effluent
AMI Turbitrace
for the measurement of low level turbidity in pure and ultra pure water
Following the outstanding success of WWEM 2008, the organisers of the world's largest environmental monitoring event have announced that WWEM 2010 will take place 10th
and 11th November 2010. Following the same format as previous
WWEM events, WWEM 2010 will again take place over two days at the Telford International Centre. The main WWEM Con- ference will be repeated on both days and a comprehensive programme of Workshops will run alongside an Exhibition featuring all of the world's major players in water regulation, testing and monitoring.
Exhibitor feedback from the last WWEM was extremely positive. For example, YSI’s Ian Thompson said, “WWEMwas a fantastic event for us; our stand was extremely busy on both days and as such we were able to demons- trate new products to a large number of existing and potential customers." An impressive list of further testimonials is featured at
www.wwem.uk.com
Visitor feedback was also very construct- ive; Ian Mewett, ICA Project Engineer at Yorkshire Water, said, "I was only able to attend on the second day, but found it very informative as well as a great opportunity to check out what is happening in the industry."
Many of the 2008 exhibitors have already re-booked, but the organisers are allocat- ing space on a first-come, first-served basis. Further details on the Conference, Work- shops and Exhibition are available at

Non-contact turbidimeter: optics not in direct contact with sample, no fouling on optical surfaces.
Manual or automated draining of the sample chamber.
Optional sample degasser to avoid the formation of interfering bubbles in samples.
Programmable automatic zero point measurement for drift compensation by integrated submicron particle filter.
Valve and connector for slope calibration with formazine according to ISO 7027.
Pressure tight sample system up to 10 bar avoids outgassing of sample.
