Drinking Water Measurement White Papers and Case Studies

  1. Singer Valve Improves Aussie Water Supply
    11/20/2012

    Without the right solution, aging water pipes, overflowing tanks and noisy valves can become chronic issues to a water retailer’s supply infrastructure.

  2. FMCW Or ToF? Which Radar Level Technology Is Best For Tank Gauging In Custody Transfer Applications?
    4/9/2018

    Measuring the level of tanks used to hold fluids for custody transfer can be expensive. This is not due to the cost of the measurement instrumentation, but to what inaccurate measurements can cost the company. Picking the right instrumentation for applications is important. Which radar level technology should you choose for tank gauging in custody transfer applications? Frequency Modulated Continuous Waveform (FMCW) or pulsed Time-of-Flight (ToF or PToF).

  3. Monitoring Lead In School Drinking Water
    5/23/2016

    The EPA’s guidance documentation “3T’s for Reducing Lead in Drinking Water in Schools and Child Care Facilities: Training, Testing, Telling” recommends for schools to routinely test their facility’s drinking water, with a focus on lead levels in drinking water fountains.

  4. How To Clean And Handle pH Sensors
    10/31/2017

    For a pH sensor to maintain an accurate reading, the sensor must remain clean. Specifically, the glass measuring electrode cannot become coated, and the reference electrode assembly must not become coated, plugged or otherwise contaminated by the process solution. Here’s how to clean pH sensors to ensure correct operation.

  5. Advantages Of Thermal Dispersion Switches For Pump Protection
    7/1/2014

    Thermal dispersion switches use similar principles as thermal mass flow meters. Fluid carries heat away from the probe tip reducing the temperature difference between a heated resistance temperature detector (RTD) and a reference RTD.

  6. Portable Parallel Analysis: Streamlining Distribution System Water Testing
    3/6/2015

    A Water Quality Specialist used the Hach SL1000 Parallel Portable Analyzer (PPA) to test 6 parameters simultaneously – all within about 8 minutes.  Previously, the procedure took 20 minutes just for one parameter.

  7. Precise Biogas Flow Measurement
    4/25/2016

    As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

  8. Are Test Strips Still Relevant For Water Analysis?
    9/26/2017

    Today’s environmental laboratories are audited and accredited companies where quality control (QC) and quality assurance (QA) reign. Advanced technology is needed to measure parameters for regulatory compliance down to parts per billion. In a world of regulatory mandates, can test strips still be used for water analysis?

  9. New Electromagnetic Water Meter Technology Improves Accuracy And Reliability
    12/26/2012

    Electromagnetic water meters are becoming more and more popular for bulk measurement of residential and commercial drinking water, especially as pricing and metering gain traction as tools for more efficient use of water and water conservation.

  10. Case Study: Optimized Quality Control In Mineral Water Plants
    4/16/2009
    Due to microbiological activity in the process, or to a lesser extent due to the reduction in nitrate levels in the raw water, nitrogen compounds may give rise to increased nitrite concentrations. By Endress + Hauser, Inc.
