  1. Boosting Accuracy For Long-Term SSO And CSO Planning 4/23/2021

    Accurate flow measurement is increasingly imperative for sanitary sewer overflows (SSOs) and combined sewer overflows (CSOs), which are a rapidly growing area of concern for municipalities.

  2. A More Cost-Effective Tool For Oxygen Injection Flow Measurement 4/23/2021

    Variable area (VA) flow meters offer an economical solution in many hazardous wastewater applications, as well as a variety of other uses, but are often overlooked by engineers and plant operators who think a higher level of flow measurement technology is necessary. 

  3. The Next Generation Of Distribution System Management And Leak Detection 4/23/2021

    As municipal water systems grapple with tightening budgets and water scarcity continues to be a growing issue, communities must look toward solutions that reduce their need for source water, bring down the costs of treatment, and allow for better management of the pipeline assets.

  4. Advantages And Disadvantages Of Available Options For Measuring Wastewater Flow In Partially Filled Pipes 4/8/2021

    A variety of devices can be used for measuring water or wastewater flow where pipes cannot be kept full. Examples include open channel flow (OCF) devices like flumes and weirs in combination with secondary level measurement devices and/or electromagnetic flow (EMF) meter options. Each has its pluses and minuses. However, new proven EMF technology can deliver higher accuracy and the best performance when sized for flow rates at levels above 25 percent filled pipe. It also offers a safer environment, simpler installation, and better measuring performance than other available options.

  5. Measuring Flow In Partially Filled Closed Pipes With An Inline Meter 8/5/2020

    The session will outline how a unique metering technology has accomplished this challenging task with superb performance and longevity. Over the course of the last 30 years, since it was first introduced, KROHNE's TIDALFLUX meter has proven to be the only product that has stood the test of time. It is a full-bore device, it has no moving parts, it is factory-calibrated, and is approved for hazardous areas and for water, wastewater, and industrial applications.

  6. The Key To Accurate Waste Gas Flow Measurement 4/20/2020

    Wastewater treatment facilities have a tremendous opportunity to utilize the biogas they generate to lower energy costs and minimize odors. However, the practice isn’t as widespread as it could be, as the precision gas flow and methane content readings required to optimize the process often clash with the misconception that biogas is messy and difficult to measure reliably. With the proper equipment, it is possible to accurately measure biogas to cut emissions and reduce or eliminate the energy bill.

  7. The Reasons Behind The Wide Array Of Liner And Electrode Choices In Magnetic Flow Meters 4/14/2020

    Electromagnetic flow meters offer significant benefits in water, wastewater, and industrial applications because they can be reliably used to measure liquid with many different characteristics. Since these devices contain no moving parts, making them virtually maintenance-free, they are becoming the workhorse for a growing number of utilities and industrial operations. Despite the advantages, however, electromagnetic flow meters are often avoided based on the misconception that there are limitations on what they can measure.

  8. Direct Burial Meters Offer Significant Savings 4/13/2020

    Most pipelines are below grade, so vaults have traditionally been installed to provide access to any place where a meter and valve are necessary. Vault pits tend to be large, and the installation is by far the biggest expense of a metering project. The good news is that direct burial metering options can greatly simplify the installation requirements, significantly lowering the costs, while also boosting safety.

  9. Evolution Of Pipeline Leak Detection 11/5/2019

    As the sheer number of pipelines crisscrossing the country continues to increase, there is an urgent need to ensure pipeline infrastructure safety. The age of many of the pipelines and the number of different products flowing makes this a challenging prospect. Now, new technology has been developed that meets the need for reliable protection that complies with regulatory requirements while eliminating false alarms.

  10. Optical Oxygen Sensors Promote Efficiency Gains 10/18/2019

    Tight control of the biological process in aeration basins is the lynchpin of wastewater treatment at municipal facilities. To perform at their peak, the “bugs” in these basins require a specific amount of oxygen. However, the air blowers controlling this process consume a significant amount of energy and thereby represent a major expense. Now, advanced solutions are available that provide a cost-effective method to measure the oxygen for automatic control in the basins without the need for frequent maintenance.
