WASTEWATER Flow Control Resources

  1. Ultrasonic Flow Measurement System Saves WWTP $72,500 Annually 10/3/2014

    If the wastewater treatment plant serving Reading, PA, and 11 surrounding municipalities has a mission statement for its day-to-day operations, it couldn’t be simpler or more critical: “95°F.”

  2. New Developments In Thermal Dispersion Mass Flow Meters 9/15/2014

    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. By John G. Olin, Ph.D., Founder/Chairman, Sierra Instruments

  3. Math Solutions: Volume Calculations 9/13/2014

    Water Online’s “Math Solutions” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), provides an understanding of the sometimes difficult calculations involved in achieving wastewater operator certification.

  4. Advanced Diagnostics of Thermal Mass Flow Meters 9/9/2014

    Many thermal mass flow meters are of the insertion type. As a starting point, proper insertion depth and straight run per the manufacturer’s recommendations should be adhered to.

  5. 4 Keys To Great Portable Ultrasonic Flow Metering 9/5/2014

    The liquid measurement market is an extremely large market with many varied measurement requirements. To get the best bang for your buck, a portable ultrasonic flow meter is a practical solution. With a portable ultrasonic flow meter, you can use one liquid flow meter in several locations throughout your flow process.

  6. Math Solutions: Flow Rate Conversions 8/4/2014

    Water Online’s “Math Solutions” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), provides an understanding of the sometimes difficult calculations involved in achieving wastewater operator certification.

  7. Best Practices for Mass Flow Controller Manufacturing 8/1/2014

    In Part 1 of our mass flow controller best practices series, Best Practices for Mass Flow Controller Selection and Installation,  Sierra’s Chief Engineer John Smitherman compiled a comprehensive list of best practices for the selection, installation and operation of mass flow meters and controllers. With so many flow measurement products and technologies on the market, it’s important to also be able to assess the manufacturer,

  8. How To Save Time & Money By Calibrating Flow Meters Onsite 7/1/2014

    If you have hundreds of mass flow controllers and meters or just a few in your lab, facility, or manufacturing process, how do you keep up with the demands of annual recalibration?

  9. 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.

  10. Instrumentation Do's And Don'ts For The Water Industry 3/12/2014

    To say that instrumentation, automation, and control are key to the modern wastewater industry is somewhat of an understatement.  With growing populations, tighter consent parameters, and the need to do more for less, operational efficiency is more and more important.
