  • Using Alternative Methods in Greenland - Qaqortoq, Greenland - Case Study

    In 2012, Leif Koch A/S had the honor of performing leakage detection as well as being witness to the repairing process. At the time, Nukissiorfiit Qaqortoq lost 5-7 m3 of water each day on their district heating plant. Unfortunately, nature of the pipes made it impossible to find the leaks without the use of alternative methods, which is why the supply company decided to contact Leif Koch A/S. ...

  • The future of leak detection starts today

    For many water engineers the day in the office begins with a look at the screen. They can analyse the results of the nightly measurements of their fresh water pipelines in a few minutes and make important decisions for the day. Are there any new leaks in the system? Using the information found, the water engineer can send his workers to precisely those points that the leak detection system has ...

  • How an Ultrasonic Flow Meter Works

    An ultrasonic flow meter utilizes ultrasound to measure the velocity of a fluid and is used in a variety of fluid applications. Ultrasonic flowmeters are ideal for water and other liquids. Clamp-on ultrasonic flow meters achieve high accuracy at low and high flows, save time with no pipe cutting or process shutdown, and are not affected by external noise. Here’s how ultrasonic flow ...

  • How Does a Water Flow Meter Work?

    A water flow meter is a device that measures the amount of water flowing through a pipe. There are several water flow meter technologies to choose from depending on the water measurement application, maintenance requirements, and budgetary terms.  Each of these types of water flow meters has a unique principle of operation, specific application benefits, and overall ...

  • What is turbidity?

    Turbidity measures the relative clarity of a water sample. It is determined by the amount of scattering that occurs when a light source is shined through a water sample. Light scattering is caused by increased concentrations of suspended particles in water that are not individually visible to the naked eye, which can give the water a cloudy appearance. This parameter is used as a general ...

  • How Does a Water Flow Meter Work?

    A flow meter works by measuring the amount of a gas, liquid or steam that passes through or around the flow meter sensors. While flow meter sensors work in many different ways, the end goal is the same: Deliver the most accurate and repeatable flow measurements for the specific application, whether for general research, process control or semiconductor processing. Flow meters measure either mass ...

  • Assessment of domestic consumption in intermittent water supply networks: case study of Puerto Ayora (Galápagos Islands)

    Intermittent water distribution systems are a stark reality in developing countries. Puerto Ayora, the centre of tourism of the Galápagos Archipelago, is not an exception, with its population and tourists suffering from scarce water resources. However, the extreme per capita consumptions, well above those in 24/7 supply situations in many other countries, contradict the (sense of) scarcity. In ...

  • Optimizing DMAs' formation in a water pipe network: the water aging and the operating pressure factors

    Dividing a water distribution network (WDN) into district metered areas (DMAs) is the first vital step towards pressure management and real losses reduction. However, other factors of water quality such as the water age must be taken into account while forming DMAs. The current study uses genetic algorithm (GA) optimization methods to achieve the desired WDN segmentation conditions in terms ...

  • Forming DMAs in a water distribution network considering the operating pressure and the chlorine residual concentration as the design parameters

    Dividing a water distribution network (WDN) in the optimal district metered areas (DMAs) formation is one task that usually troubles water utility managers. The present paper utilizes optimization methods to achieve desired segmentation conditions in terms of (a) operating pressure reduction, thus reducing the system's real water losses and (b) residual chlorine concentration reduction thus ...

  • How Does a Water Flow Meter Work?

    A water flow meter works by measuring the amount of water that passes though the flow meter. The most common mechanical types work by measuring the speed of flowing water that causes a turbine or piston to rotate. The volumetric flow rate of the water is proportional to the rotational speed. Other water flow meters include ultrasonic, magnetic and vortex flow meters. The best type of water flow ...
