  • New Developments in Thermal Dispersion Mass Flow Meters

    Introduction This paper describes a newly developed microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and automatically manages changes in gas selection, gas temperature, gas pressure, and outside temperature. This new mass flow meter is ideally suited for apportionment applications ...

  • Match, don't mix: implications of institutional and technical service modalities for water governance outcomes in south Indian small towns

    This paper seeks to contribute to the limited literature on water governance in small towns in India. For assessing water governance, we propose a broad framework encompassing adequacy and affordability, equity, sustainability and responsiveness. Analytically, the concept of ‘service modality’ is expanded to include not only institutional arrangements but also water resource deployment, and ...

  • 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 ...

  • Mexico - HydroMet Calibration Vehicle with WS501 weather station on board - IGS Hydro - Case Study

    The Office of Meteorology and Hydrology in Mexico equipped a vehicle with measurement technology for verification of their Hydro-Met stations. We are proud that they decided to choose our smart WS501 compact weather station (All-in-one) for measurement of the meteorlogical parameters. With the integration of the smart weather sensor WS501-UMB the calibration vehicle can provide accurate data ...

  • 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 ...

  • 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 ...

  • 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 ...

  • The Function of an Ultrasonic Flow Meter

    Running a water management operation requires taking a wide range of measurements. In addition to measuring the flow in your system, many systems must measure the water level of their channel, and one of the best tools for accomplishing this goal is an ultrasonic flow meter. ...

  • 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 ...

  • Application of a water balance adapted to intermittent water supply and flat-rate tariffs without customer metering in Tiruvannamalai, India

    Establishing the water balance developed by the International Water Association (IWA) is a worldwide applied approach to determine and analyse water losses in water distribution systems (WDS). The water balance covers those parts of a WDS within the responsibility of the water utility. Water losses occurring ‘before’ a customer meter are at the expense of the utility, while water lost or ...
