Drinking Water Measurement

  1. (Ultra)Sound Opportunities For Aging Metering Infrastructure
    7/30/2018

    Most people accept that major purchases in life — e.g., housing, automobiles, appliances — come with cyclical budgeting impacts that require amortizing costs over the long term, through savings or borrowing. Why should anyone expect the national water infrastructure to be any different?

  2. Smart Water: Remote Sensing
    7/19/2018

    Automated metering systems (AMSs) or “smart meters” can provide valuable data for electric and water utilities. Data analytics can be used to improve customer service, boost conservation, monitor the system, and even forecast demand. An ultimate goal might be to eventually monitor everything from streetlight intensity to fire hydrants.

  3. Benefits Of Off-Line Calibration Of pH And ORP Meters
    7/17/2018

    One of the most commonly used measurements in the water and wastewater industry is pH. A measurement of how acid or alkaline a substance is, a pH reading can instantaneously indicate a problem with the water. Another common and useful measurement is oxidation-reduction potential (ORP). Treatment facilities use ORP sensors to optimize disinfection and biological nutrient removal processes.

  4. Instrument Resiliency For Tough Times
    7/17/2018

    Utilities have relied on numerous instruments for process control and monitoring for many years. But in today’s world, instrumentation is more crucial than ever. Most treatment facilities, pump stations, and other system components are automated to some extent. Instrument failure or inaccuracy may result in serious public health or environmental consequences. Resilient instruments can power through adversity and keep utilities running smoothly.

  5. Operational And Maintenance Benefits Of Portable Flow Instruments
    7/16/2018

    Accurate flow measurement is critical for process control and regulatory compliance. Flow meters are essential instruments for water and wastewater facilities, installed at multiple locations throughout entire systems. For the most part, these are permanent installations. However, portable flow instruments prove beneficial in certain situations.

  6. Six Top Factors To Consider When Selecting A Flow Meter
    7/13/2018

    Water utilities rely on accurate and dependable flow measurement for critical process controls. Regulatory agencies also require flow monitoring and reporting, with specific accuracy limits.

  7. How Calibration Impacts Flow Meter Performance
    7/12/2018

    Utility managers and operators rely on flow meters to provide critical information for process monitoring and control. They require and fully expect the flow data to be accurate and reproducible.

  8. How To Avoid System Downtime When Installing Flow Meters
    7/11/2018

    Water and wastewater utilities rely on accurate flow measurement for important process controls. These may include recycle streams, chemical dosing systems, and other operational functions. In addition, regulators require utilities to measure certain flows, such as treatment plant influent and effluent and potable water pumping. Accurate flow measurement is also important for monitoring and reducing unaccounted-for water.

  9. The Challenge Of Flow Disturbances On Meter Accuracy
    7/10/2018

    Accurately measuring flow is critical for water utility operations. Also, regulatory agencies mandate flow monitoring and require annual calibration of meters. But even a meter in perfect condition and properly calibrated can read inaccurately. Flow disturbances are a common cause of accuracy and repeatability errors.

  10. Sensitive Determination Of Iron In Drinking Water, Mineral Water, Groundwater, And Spring Water Using Rapid Photometric Tests
    7/3/2018

    The quality of drinking water is regulated by a variety of guidelines, such as the EU Council Directive 98/831,2 and WHO guideline. The key principles used to define these limits consider both health hazards and sensory and technical reasons. Iron, for example, does not exhibit a risk for health in concentrations usually found in drinking water.
