  1. 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.

  2. Case Study: Newport News Uses Emerson Ozone Instrumentation For Safe, Effective Disinfection
    5/22/2006

    Maintaining the quality of the water supply is the top priority for municipal drinking water treatment plants across the country. Water plants use several treatment processes to ensure water quality and safety, and these treatment steps include disinfection. Traditionally, chlorine is used in both primary and secondary disinfection treatments and has been used since 1908. Some water plants are moving to ozone for primary disinfection. One water utility that is taking this direction is Newport News Waterworks.

    9/14/2017

    Emerson Automation Solutions has introduced the industry’s first WirelessHART® pressure gauge. The Rosemount Wireless Pressure Gauge enables remote collection of field data, keeping operators updated on changing field conditions and improving personnel safety by reducing manual operator rounds and field exposure.

  4. Primary Wastewater Treatment: Influent Monitoring
    11/10/2013

    The raw sewage entering a wastewater treatment plant comes from a variety of sources. In addition to effluent from domestic users, effluent from industrial users and storm water run off can be present.

  5. 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.

  6. 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.

  7. Leak Detection Using Conductivity
    11/11/2013

    Virtually all industries from food and beverage to chemical processing use heat exchangers, condensers,or jacketed vessels. Leakage of the process into the cooling water represents a loss of product and can be a source of fouling or corrosion in the cooling water system.

  8. Wireless pH Monitoring Of Storm Water Runoff And Final Effluent
    3/1/2010

    Wireless pH instrumentation is appropriate in several applications in the power industry. The principal benefit of a migration to wireless technology from more traditional copper cable is cost reduction. A wireless network requires none of the cable, conduit, or switching hardware which represent the largest expense in most plant networks. By Emerson

  9. Application Note: pH Control Protects Membranes In Reverse Osmosis
