This paper presents the results of 12 V-Cone DP Flow meters tested over a period of 17 years. Service applications for the V-Cones included natural gas as well as coke oven gas measurement, a dirty aggressive fluid that is problematic over long period of time for most flow meters. All testing was conducted in air by a 3rd party calibration laboratory, CEESI Colorado. Results will be presented for each of the meters over the 17 year span. Conclusions and recommendations will be made to the long term performance and recalibration intervals for the V-Cone flow meter.
Call it what you want, but a busted pipe spells nothing but T-R-O-U-B-L-E.
A Municipal Water Plant in the Southeast United States treats and supplies potable water to a large metropolitan area. Part of the process requires accurate flow measurement of the water from individual pumps to the main distribution system.

Trimble Telog offers a comprehensive remote monitoring system, Telogers, for wastewater collection system operators. Telogers provides an automated system of collecting, archiving, analyzing, presenting, reporting and sharing data from collection system remote assets such as flow meters, rain gauges, CSO/SSO surcharge sensors, lift stations, pretreatment water quality, air quality, and pressure sensors.
The estimated $30-million West Side Loop 48-inch Replacement Project is one of three capital projects being conducted by the Cobb County-Marietta Water Authority to provide additional water to western Cobb County and Paulding County in Georgia. For the project, a 48-year-old, 36-inch pre-stressed concrete cylinder pipe (PCCP) that recently failed is being replaced with 48-inch ductile iron pipe.
Mid-to-large size facilities and campuses inevitably have hundreds of flow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. By Matthew J. Olin, President & CEO, Sierra Instruments, Inc.
As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

At a water treatment plant that provides drinking water for distribution to a large area of customers, a contractor decided to switch to SITRANS FM MAG 5100W flowmeters. A local representative saved a the contractor time and money by recognizing the need for the magmeter to be isolated from the piping protection before startup, which also saved the customer from added downtime.
The Siemens Channel Partner in Oregon, has a customer from an engineering firm who also volunteers for Engineers Without Borders (EWB). The Portland chapter of EWB took on a project in Les Anglais, Haiti, to restore their drinking water supply system that had been disrupted in the Fall of 2008.
A suburban township in the upper Midwest U.S. buys their drinking water from a major municipal water district. The municipality has many customers and has implemented contracts with each of its wholesale customers that limit the peak flows and the time of day in which they may occur. If the wholesale customer exceeds the limit, they are assessed significant surcharges.
A large east coast water supplier faced a number of challenges with one of its pumping stations. It was built more than 35 years ago on a 25’ earth mound (“ant hill”) to protect it from flooding, the pumping station was becoming very expensive and inefficient to operate.
A U.S. company develops energy technologies that are environmentally sustainable and provides their customers with the ability to use their energy sources in a more practical and cost-effective manner.
As the world’s population continues to increase at a fast pace, more food and water will be needed to sustain humanity. In the past 50 years, we have tripled our need for water and food, and there are no signs of this trend slowing down. As a result of these conditions, smart, innovative agricultural practices are needed now more than ever. Technology can, and already does, aid agriculture in innumerable ways. One prominent part of agriculture that can use technological innovation to increase efficiency and effectiveness is irrigation.
One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
The water municipality at a mid-size city in the Western region of the U.S. serving a population of about 180,000 people needed to address a chlorine disinfection system problem at one of its water treatment plants.
Facility administrators will find the advanced ST100 Series Thermal Mass Air/Gas Flow Meter from Fluid Components International (FCI) helps them improve the accuracy of specialty gas point of use and sub-metering operations to achieve accurate billing in their labs for better cost tracking and control.
Fox Thermal Flow Meters use a constant temperature differential (constant Δ T) technology to measure mass flow rate of air and gases.
Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gaining an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas including supply planning, maintenance and resource deployment, leakage detection and rectification and the overall environment, in terms of controlling abstraction and reducing unnecessary draw on natural resources.
The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.
Pressure reducing valves (PRVs) are used throughout water distribution systems to reduce pipeline pressure to a predetermined set point. This decreases water loss and prevents pipe breaks.
