  • DFM 5.0 doppler flow meter for frac sand slurry flow monitoring

    CanFrac Sands Ltd. of Lloydmister Saskatchewan (Canada) needed a flowmeter that could accurately measure sand slurry flow without being damaged by this highly abrasive product. They selected the Greyline DFM 5.0 Doppler Flow Meter with a clamp-on ultrasonic sensor mounted on the outside of a pipe. CanFrac produce “fracturing sand” used by the oil and gas industry. This special type of ...

  • Portable Monitoring Instruments Solve Flow Rate Mystery

    The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow. The Township started by video taping all of the lines ...

  • Implications of observed and simulated ambient flow in monitoring wells

    The authors of this paper present compelling evidence that conventional monitoring wells act as vertical conduits whenever vertical hydraulic gradients are present (i.e., at most sites). Vertical flow within wells due to natural hydraulic gradients not only makes it impossible to accurately define the vertical distribution of dissolved contaminants within the aquifer, but it can transport ...

  • 156 Flow Monitors Installed in 14 Days

    San Diego, CA - The City of San Diego Metropolitan Wastewater Department received a formal consent decree from the EPA in 2005. In response, the department decided to replace and update the flow monitoring system they had in place. They selected ADS<sup>®</sup> for the challenge of installing 156 flow monitors in sites that were scattered across varied terrain, including canyons and ...

  • Monitoring Flow Rate in a Channel to Minimize Water Pollution

    Recently a wastewater management district in Cleveland contacted CAS DataLoggers to supply an automated monitoring solution for their environmental project. In most cities, sanitary sewers and storm sewers were separate, so that storm water was diverted into a nearby lake. However, Cleveland had only one sewer available, so all of the flow went to the ...

  • Effective monitoring improves sewage flow management case study

    SmartScan 50 introduces an effective solution for flow measurement of sewage water in one of Poland's municipal waste water treatment plant. The city of Zblewo, Poland provides waste water treatment services to its inhabitants. The plant sought an ultrasonic measurement solution for monitoring the raw sewage flow during the treatment process. The problems When entering the ...

  • An asymptotic observer-based monitoring scheme for a class of plug flow reactors

    In this paper a monitoring tool is designed for a class of plug flow reactors whose mathematical model is described by a set of first-order partial differential equations with different coefficients in the convective terms. The infinite dimensional structure of such a tool is derived according to the methodology established in the design of the well-known asymptotic observer. As a consequence, it ...

  • AVFM 5.0 area-velocity flow meter monitors sewage lagoon discharge flow

    The Township of South Glengarry in Eastern Ontario discharges continuously from their 72,000 m3 sewage lagoon. But they ran into flow measurement problems when their magnetic flowmeter was unable to detect seasonal low flow rates. Operations Manager, Shawn Killoran selected a Greyline AVFM 5.0 Area-Velocity Flow Monitor because it was simple to install in a horizontal discharge pipe from the ...

  • OCF 5.0 open channel flow monitors - monitor infulent at Long Sault WWTP plant

    Greyline Open Channel Flow Monitors were installed at the Wastewater Treatment Plant in Long Sault, Ontario when the SBR plant was originally commissioned in 1995. But after 16 years of continuous service, components for the old models became obsolete. Plant operators Caneau Water and Sewage Inc. decided to replace the instruments and new Greyline OCF 5.0 Open Channel Flow Monitors were installed ...

  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...
