  1. Continuous Total Chlorine Measurement And Recording To Meet EPA Discharge Requirements
    11/21/2011

    Total chlorine can be determined using the Rosemount Model TCL. This system is a sample conditioning and measuring system for the continuous determination of total chlorine in water.

  2. Improved Silo Contents Management Using 3D Solids Scanners
    5/7/2015

    Measurement of solids is a challenge for a number of reasons. The solids surface is uneven and shifts as the silo is filled or emptied.

  3. Utah Water District Saves Time And Resources, Improves Accuracy By Upgrading Sensors And Analyzers
    7/20/2015

    Monitoring chlorine and fluoride levels in the drinking water of Utah’s Taylorsville-Bennion Improvement District used to be expensive, labor intensive, and often sensitive to interference from the vari­able frequency drives used to operate the chlorine injection pumps. That is, until the district upgraded to Rosemount free chlorine and fluoride sen­sors and analyzers from Emerson.

    Introducing the easy-to-use Model 56 Analyzer. The high resolution full-color screen provides easily viewed process measurements, on-screen data trend graphs, and details user help screens. This advanced analyzer has data logger, event logger, and a USB 2.0 data port.
  5. Powering Safety Systems - Significant Power 'Headroom' Is Good Practice
    12/15/2014

    One of the most common sources of Fire and Gas detection system failure is power supply interruption and disturbance. Power supply specifications of an instrument refer to the voltage that must appear at the instrument power terminals, not the power supply rated output.

  6. How One Plant Found Great Service Through Turbidity Analyzers
    10/3/2016

    The nearly 16,000 people in Calhoun, GA, rely on two drinking water treatment facilities — one that pulls its water from a river and another that pulls from groundwater — that process about 9 MGD. The turbidity of the river’s water can fluctuate dramatically, so the operators rely on the surface water treatment plant’s turbidity analyzers to ensure that they are serving the population as they should.

  7. Application Note: Ozone Measurement In Potable Water
    3/1/2010

    Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.

  8. Coagulation and Flocculation
    9/18/2013

    Water is clarified using the processes of coagulation and flocculation, which remove suspended solids (turbidity) from water by causing the suspended particles to aggregate into a slime, that settles out of the water.

  9. Point Versus Continuous Level Measuring Technologies
    11/7/2017

    While point level measuring approaches are regarded as simple and user friendly, they lack the capabilities of more sophisticated continuous measuring instruments.
