31. 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.

32. 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.

33. 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.

34. 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.

35. 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.

36. 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.

37. 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.

38. A Cost-Effective Answer To Partial-Pipe Flow Metering 10/14/2019

    One of the most perplexing challenges for wastewater plant operators is the need to measure the various sources of influent. This is especially true for closed-pipe systems where the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement.

39. Navigating The Partial-Pipe Flow Challenge 10/10/2019

    One of the most perplexing challenges that wastewater plant operators face is the need to measure the various sources of influent. For closed-pipe systems, the use of traditional flow devices requires intensive and expensive engineering to keep the pipe full at the point of measurement. The good news is that there is an emerging solution that measures flow in a less-than-full pipe.

40. Squeezing Every Last Dollar From Biogas 10/8/2019

    A growing number of wastewater treatment plants are banking on biogas from their sludge as a supplemental power source. Unfortunately, biogas is notoriously difficult to quantify. Ultrasonic flow meters specifically designed for biogas applications can provide a solution that addresses many of the issues created by traditional technology.
