Water Instrumentation White Papers & Case Studies,

  1. Why A Little Knowledge About Sensors Can Be A Dangerous Thing
    6/4/2014

    Every day our technical support people answer questions on the selection of sensors for pH, ORP, conductivity, dissolved oxygen and turbidity. No issue generates more confusion than cell constants for conductivity sensors. The vast majority of returns we process are for conductivity sensors that were ordered with the wrong cell constant. It turns out that cell constants are something that we all read but that most of us don’t really understand. Pick the wrong cell constant for a probe and your analyzer will happily give you numbers to 3 significant digits. The only problem is those numbers are wrong.

  2. Solving A Taste and Odor Problem Step By Step (Article)
    5/22/2014

    The City of Alliance Ohio’s water system has experienced annual Taste and Odor (T&O) events since the mid 1950’s, when the first of two reservoirs, Deer Creek Reservoir, was placed into service. Nutrient contaminants, in particular phosphorous, in the watershed accumulate in the reservoirs causing algal blooms.

  3. AMERICAN Valve And Pipe Groups Join Forces To Serve The Citizens Of Eastern Pennsylvania
    5/8/2014

    Together, AMERICAN Flow Control and AMERICAN Ductile Iron Pipe are providing a complete package of valves, hydrants and pipe for a new waterline to serve the eastern Pennsylvania communities of North Wales and Chalfont Borough.

  4. Two-Way Fixed Network Helps Texas Community Become ‘City Of The Future’
    4/11/2014

    In January 2014, the city of Meadows Place, Texas, became the first city in Fort Bend County to fully convert to an Advanced Metering Infrastructure (AMI) fixed-network system. At the same time, the city also implemented a complete meter change-out for its 1,600 customers. Both projects represent large initiatives for the self-proclaimed “little city” with a population of 4,600 citizens.

  5. Versatility Of Thermal Mass Flow Meters
    3/10/2014

    There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

  6. The Benefits Of A Venturi Meter
    2/19/2014

    With the introduction of new measurement technologies and the myriad of performance claims from sale literature, it’s easy to lose sight of the important elements that an effective flow meter offers no matter what technology is used. Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.

  7. Protecting Our Water – Keep Chemicals In The Tank
    2/12/2014

    Leaking or overfilled tanks can cause environmental problems, contaminate drinking water, and cost a company millions of dollars. Proper instrumentation, monitoring and control can prevent these problems. By Bill Sholette, Level Products Business Manager, and Ricardo Chavez, Solutions Business Manager, Endress+Hauser

  8. Making Accurate pH Measurements
    1/21/2014

    Like the old saying goes, give a man a watch and he always knows what time it is. Give him two watches and he never knows the correct time. What do watches have to do with pH? In this article, we will tie the analogy of accurate time to pH measurement and show how to make more accurate, dependable and believable pH measurements by using three pH sensors.

  9. Thermal Dispersion Technology Helps Utility Meet Federal Environmental And Health Regulations
