Praised by research scientists and water quality engineers and cited in peer-reviewed journals, the FlowCAM is used in a range of industries such as food, beverage, pharmaceutical, biotechnical, marine and water.

Using Bentley's WaterGEMS water distribution modelling software integrated with a geographic information system (GIS) and supervisory control and data acquisition (SCADA) system (both introduced into the utility in the past two years), Westernport Water's managers were able to achieve a high-performance, automated system. This targeted investment in new technologies is currently delivering substantial cost savings and contributes to the effective operation and management of more than $43 million in water assets. The Open Spatial GIS, in conjunction with WaterGEMS, enables simple and easy updates of the system, including all new subdivisions. The Control Microsystems SCADA system allows field-measured data to be brought directly into WaterGEMS using the modelling software's SCADAConnect and Darwin Calibrator modules. Since SCADAConnect can use both historical and real-time data, the model is constantly up to date, but also has tables of previous values for trending and projections. This means that flow, pressure and tank-level data for each demand zone can be fed on a real-time basis, enabling the system to model real-world conditions. Using the imported SCADA values, Darwin Calibrator, and the demand inversing tool in WaterGEMS, Westernport Water engineers can proportionally change the demand values assigned to those nodes within each demand zone. This innovative first for the water industry in Victoria allows the model to continually update demand groups. As a result, all calculated values in the water model are more accurate, since the exact flow from the SCADA system is used to calculate, for example, velocity, losses, and system curves. An up-to-date and accurate model gives engineering design and operational personnel the best possible platform for decision making. Cost benefits, efficiency and environmental improvements Previously, Westernport Water had engaged the services of external contractors to manually upgrade and calibrate its water model. The SCADAConnect technology with real-time updates will save Westernport Water the cost of these calibrations, which came to around $80,000. Additionally, the WaterGEMS water model will help deliver savings in leak detection by measuring and identifying non- revenue water. Westernport Water aims to achieve a 25% reduction in water losses and recover up to $85,000 (retail value) of water. Reducing water losses also means that less water will need to be pumped to customers to achieve the same level of service, so carbon emissions will be reduced as well. LOW-COST, HIGHLY SOPHISTICATED ANALYSER/CONTROLLER FROM PI For water engineers, many modern controllers and analysers provide just too much in terms of standard features that need to be paid for. For this reason Pi has developed the CRONOS, a highly sophisticated multi-lingual controller that is both simple to use and low in cost. The new controller follows the maxim "everything you need -- and nothing you don't". CRONOS does indeed have everything you need in an analyser/controller, with up to three universal inputs and up to three universal analogue outputs, up to four relays and options for Profibus, Modbus, LAN and other comms protocols. The user interface is highly intuitive and comes equipped in multiple languages and a set-up wizard for ease of use.
