  • 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 ...

  • 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 ...

  • Preventable Mistakes with Vortex Flow Meters

    Vortex flow meter technology is an ideal technology for many applications particularly saturated and supersaturated steam, volumetric water applications as well as flow energy management (natural gas, compressed air, steam, water) in facilities and large campuses. In some of these applications, vortex installations can be tricky and take flow expertise for the most successful installations. Kam ...

  • 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 ...

  • Smart Water Metering For Smart Cities

    One of a city’s most important pieces of critical infrastructure is its water system. With populations in cities growing, it is inevitable that water consumption will grow as well. The term “smart water” points to water and wastewater infrastructure management system. A smart water system is designed to gather meaningful and actionable data about the flow, pressure and ...

  • Sound recording to characterize outdoor tap water use events

    Obtaining disaggregated water use at the home typically involves expensive smart metering. In this study, water use events at the outdoor tap were captured using recorded sound. Outdoor taps at 10 homes were fitted with small-sized microphones and digital sound recorders. Sound files recorded over a 1-month period were used in the analysis. In the preliminary analysis, a human operator browsed ...

  • Adapting the IWA water balance to intermittent water supply and flat-rate tariffs without customer metering

    The International Water Association water balance is an approach applied worldwide for determining and analysing water losses in water distribution systems (WDS) up to the point of customer metering. Thus, water losses occurring ‘before’ a customer meter are at the expenses of the water utility while water lost or wasted ‘after’ the meter is paid for by the customer. This applies to systems ...

  • Investigating unaccounted for water and its components in Zomba City water supply system, Malawi

    This study assessed Unaccounted for Water (UFW) in Zomba City, Malawi in 2009 and quantified its real and apparent loss components. The study was carried out in the period January–May 2009 and focussed on three selected water supply zones (Airwing, Malonje and Sadzi) especially for determination of the components of non-revenue water (NRW). Field measurements of flow and utility records formed ...

  • U.S. utilities increasing water reuse investment

    Decreased technology costs are prompting more municipal water utilities in the United States to invest in new water reuse infrastructure. In fact, a new forecast projects more than $18 billion in water reuse and desalination projects are on tap in 17 states, according to Bluefield Research analysts. Although water scarcity is a conventional driver for this type of project, the analysts say the ...

  • In the depths of the oceans, human activities are beginning to take their toll

    Once seen as too remote to harm, the deep sea is facing new pressures from mining, pollution, overfishing and more. Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for another 15,000 feet (4,600 meters) to the seafloor — roughly the ...
