  • Open Channel Flow - The use of Level sensors for open channel flow measurement

    Open Channel Flow - The use of Level sensors for open channel flow measurement Level sensors from SolidAT are implemented in Open Channel Flow applications. In these types of applications, the level sensor is installed above a special water flow structure and accurately measures level of flowing water or wastewater. The sensor then calculates flow through the structure ...

  • Improved Open Channel Flow Measurement & Control Using Pulsed Hybrid Flat Bed Magmeters

     ABSTRACT This paper introduces Pulsed Hybrid flat bad magnetic flowmeter techniques and how they improve the quality of flow measurement and control over existing art, normally with significant cost savings in operation and installation. The flat bed magmeters have been extensively tested in the laboratory and on-site, with details given for a particular site case. Such tests gave ...

  • Efficient investigation on fully developed flow in a mildly curved 180° open-channel

    Turbulent flow in meandering open channels is one of the most complicated and unpredictable turbulent flows as the interaction of various forces, such as pressure gradient, centrifugal force, and wall shear stresses severely affect the flow pattern. In order to improve significance in engineering application, understanding the overall flow characteristic is the focus. This paper presents the ...

  • Effective monitoring improves sewage flow management case study

    SmartScan 50 introduces an effective solution for flow measurement of sewage water in one of Poland's municipal waste water treatment plant. The city of Zblewo, Poland provides waste water treatment services to its inhabitants. The plant sought an ultrasonic measurement solution for monitoring the raw sewage flow during the treatment process. The problems When entering the ...

  • Flood modeling and mitigation measures in an urban environment – a Case Study, Victoria, Australia

    Introduction: Flooding on urban basins is intensifying due to rapid urbanization. Flooding primarily occurs because of drainage congestion of inland flow and/or over bank flow of rivers during severe rainfall events. Rapid urbanization is causing a major change in rainfall-runoff phenomenon and the drainage system as well. The overland flow pattern is becoming complex due to huge structural ...

  • Case study - Flowmeter troubleshooting at the township of North Glengarry

    The Problem... The forcemain meter at the pump station read five times higher than the open channel flowmeter at the lagoon 2 km away. The Township needed to determine which of the two flow meters was reading incorrectly. Troubleshooting Forcemain Flow... First step was to evaluate performance of the 12” magmeter at the sewage pump station. The cost ...

  • Kinematic wave computation using an efficient implicit method

    The kinematic wave theorem is the simplest and widely employed distributed routing method used in practical applications for the computation of flood wave propagation in overland and open-channel flows with steep topography. In this paper, an efficient finite-difference implicit MacCormack scheme is developed for the simulation of one-dimensional kinematic wave flows. Simulated results are ...

  • Heat recovery from wastewater

    Heat recovery from gray water is particularly important in water-intensive industries such as pulp and paper plants, dairies and breweries. Rather than flushing used water down the drain, consider whether a heat exchanging system can help you put that energy to work in your process again. Most plant operators arc aware of the need to save money and reduce the environmental impact of their plant ...

  • How to tap the energy savings in greywater

    Many operators of offices, hospitals, hotels, large condos, and other buildings are aware of the need to save money and reduce their environmental impact, through better water management. The result has been the growth of ways to reduce water consumption, ranging from low-flow show-crheads to landscaping that requires minimal watering. Building operators are also aware of a similar need to ...
