81. 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.

82. Aeration Basin Air Flow Monitoring At A Stockholm Wastewater Plant 12/20/2013

    At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent

83. Level Measurement Showdown: Ultrasonic Vs. Radar 12/16/2013

     In the level measurement world, there is a rivalry between the two most commonly used measurement instruments: ultrasonic, which uses sound-based measurement, and radar, which uses high-frequency electromagnetic waves to determine distance.

84. Pulse Burst Radar 'Levels' Competition For Chemical Waste Tank Process Control 11/15/2013

    Our customer case studies illustrate how our proven level and flow controls are helping industry leaders improve the safety of their mission-critical applications. This recent case study demonstrates that pulse burst radar technology can provide a highly reliable level control solution for challenging process applications.

85. Thermoplastic Double Wall Piping Systems—What You Need to Know 7/5/2013

    Double wall piping systems are essentially a piping system within a piping system. The inner pipe is referred to as the “primary” pipe, while the outer pipe is referred to as the “secondary” or “containment” pipe. The goal of double wall piping is to create a failsafe system where the secondary containment piping would contain any leaked fluid if a failure occurred in the primary piping. Available in a variety of materials, double wall piping systems are ideal for many applications. By Steven Dolejsi, Applications Engineer, IPEX USA, LLC

86. Should You Trash Your Flow Meter? 4/10/2013

    Generally speaking, market research reports aren’t terribly exciting reads, but they are at times enlightening. Studies on how specific technologies are being applied can reveal trends for the industries they serve — for example, flow meters in water and wastewater. I recently came across some interesting analysis on the subject, homing in on what they reveal about our corner of the world.

87. Monitoring Stormwater Outfall Study In North Carolina Assesses Impacts Of Discharge To Coastal Ecosystem 11/17/2011
    Stormwater outfalls that flow into coastal waters can affect human and environmental health.
88. Water Alternating Gas Injection System Requires Compact Flow Measurement Solution 10/7/2011

    A major oil/gas producer in the Southeastern U.S. needed to implement enhanced oil recovery (EOR) technology to boost production in a mature oil field. For the past 25 years the company had been using water-flooding, but this technology was no longer providing the desired output. The field’s first well had been drilled in 1942.

89. Refinery Cooling Water System Maintenance Problem Solved With Hot-Tap Insertion Mag Flow Meter 10/7/2011

    A large oil/gas refinery located in the Southern US along a major river utilizes water from the river for process cooling in its operations. A large amount of water is used in the refining process by the plant that must be treated after use in the plant and then returned to the river. An accurate and low maintenance flow monitoring system is essential to keep water intake, treatment and return operational costs as low as possible.

90. Case Study: FMU90 And FDU92 Sensor Provide Level Control In Aeration Basins 8/10/2011

    The Prosonic S FMU90 and FDU91 ultrasonic system is used for automatic level control in aeration basins. By Endress+Hauser, Inc.
