12 Water/Wastewater Flow Meters for Challenging Locations
OTT Hydromet (Germany) is going to expand its portfolio. Based on close cooperation with the US manufacturer Hach, OTT is now able to offer measuring instruments which provide flow measurement also in locations that are commonly considered to be challenging.
Since the OTT current meter had been created, OTT Hydromet has gained reputation as a reliable and competent partner in precise flow measurement for hydrological applications. Now, the cooperation with Hach makes it possible to offer measuring instruments that have proved in hydrological borderline areas. Small runoff ditches featuring low water level, low velocity inflows or even shooting water – a solution for even such challenges is now available from OTT. Moreover, the new units are ideally suited to be used for gravity pipelines and, depending on type, may be used for both measurements in smaller diameter pipes such as water passages under roads, culverts, or drainage pipes and in the municipal sewage network.
OTT provides three sensors from the Hach product range: Flo-Dar (radar), Flo-Tote (magneto-inductive), and Sub AV/AV9000 (Doppler ultrasonic). The instruments are fitted with proven Marsh-McBirney or American Sigma sensors. Each unit uses another measuring method since each point of use is unique and individual solutions are required. All units may easily be connected to the FL900 flow logger – which is particularly beneficial for use in portable applications.
Whether the feeding flow rate is needed for a sewage treatment plant or for sewage billing purposes, whether it is required to perform monitoring tasks in small runoff ditches or to size channels or pipes – the new products are suitable for a variety of applications.

26430pr@reply-direct.com New On-Line and Laboratory Analysers, both for Acute Toxicity in Water
The Easychem Tox on-line from Alliance Instruments (France) is a fully automated analyser for toxicity monitoring of water samples, using live cultures of luminescent bacteria, combined with the quantitative measurement of chemical parameters applying standard spectrophotometric & fluorimetric methods (up to 10 chemical parameters).
The system is programmed to manage three bacterial vials in succession, thus enabling up to one month of unattended operation. The instrument provides local storage and immediate data transmission by FTP, HTTP or SMS, with alert service.
The Easychem Tox for laboratories is the first discrete analyser to utilise a Cuvette Quality Assurance system, which offers automated system Quality control, in addition to automated analysis. Easychem Tox is also the first discrete analyser to utilise a patented, integrated direct read luminometer based on high sensitivity photomultiplier designed for
multitasking and high output rates. The instrument can analyse up to 45 samples/hour in order to measuring Acute Toxicity.
In compliance with ISO 11348-3, the most common toxicants that can be detected by the instruments in the samples are: Biotoxins, Heavy metals, Herbicides, Pesticides, Oil contaminants, PCBs, Polycyclic aromatic hydrocarbons...
For both, AMS Systea have specifically created ready to use reagents for Acute Toxicity and other chemical parameters, developed, tested and validated by our Application Laboratory.

Industrial facilities use large volumes of cooling water from lakes, rivers or oceans to cool their plants in order to remove heat from a machine or system. These facilities are steam electric power plants, chemical manufacturers, petroleum refiners, and manufacturers of primary metals like iron, steel and aluminum.
Cooling methods can vary widely in their structure and composition of cooling water. It may be recycled through a recirculation system or used in a single pass once-through cooling (OTC) system. Open recirculating systems rely upon cooling towers to remove heat. In closed recirculating systems, heat removal is accomplished with negligible evaporative loss of cooling water. Furthermore, chemicals may be added, e.g. to prevent biological growth or stabilising the hardness. In that case, cooling water has to be monitored continuously to protect the environment and/or the cooling system itself. Even if there are no chemicals added, a heat conductor breakdown can also pollute the cooling water. For that reason, the need of reliable online monitoring is significant.

LAR AG (Germany) offers a wide range of applicable online TOC analysers which offer optimal solutions for every cooling water challenge. The LAR ultra-series, using the robotic injection system, fit best when there are chemicals added or any other solids present in water. LAR's TOC analysers, using the injection loop system, offer the optimal solution for clean cooling water applications without chemicals and solids. Alternatively, the continuous TOC analyser QuickTOCuv using the UV persulphate method suits also well.
In conclusion, the selection of a TOC analyser depends on the composition of cooling water. For every cooling water application LAR AG offers the optimal solution.
