  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • Determination of Flow Rates in part-filled Applications using the Radar Method

    Introduction The radar measurement method plays an increasingly important role in the water and wastewater field. This is particularly reflected by the "Metering outside of the medium" trend. Flow measurement using radar which enables contactless measurements thus becomes a major focal point. It features a wide range of applications and hence is useful as permanent measurement system for ...

  • Data Centre CRAC unit efficiency improvements

    One of the main types of project Munters look at is energy efficiency improvements within the thermal management side. One of the easiest changes that can be made is swapping out the old AC powered motors for EC powered impellors. the reductions in energy is considerable, with some older belt drive unit changes measuring a saving of over 60% this is due to the design of the new impellors and the ...

  • Detect Leaks and Analyze Water Consumption with WaterSignal

    Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

  • Blockchain Technology Can Boost Climate Action

    Experts meeting at the recent UN Climate Change Conference in Bonn in May have said that a new technology called “Blockchain” could play a major role in tackling climate change. A Blockchain is a distributed database that is continuously updated and verified by its users. Each added block of data is “chained” and becomes part of a growing list of records, under the ...

  • Lagoon Discharge Flow Monitoring

    Open Channel Flow Monitoring without a Flume or Weir Township operators liked the Greyline AVFM 5.0 datalogger reporting system where formatted flow reports (total, minimum, maximum and average) could be downloaded automatically to a USB memory stick without carrying a laptop to the site. The Township of South Glengarry in Eastern Ontario discharges continuously from their ...

  • Scottish Water Flow Monitoring Contracts

    Scottish Water commissioned HL in 2007 to deliver two separate flow monitoring contracts to help improve the water companies understanding of the yield and low flow conditions at several water supply catchments across Scotland. One project involved the installation of reservoir level, inflow flow gauges and recording raingauge devices in nine reservoir catchments in South West Scotland. Although ...

  • Green House Gas Flow Monitoring

    This article addresses the challenges and solutions to flow measurement of green house gases in various industry applications.  GHG flow monitoring regulations are discussed and addressed. Last year the EPA implemented new regulations entitled “Mandatory Reporting of Greenhouse Gases.” The new regulations called for certain facilities emitting 25,000 metric tons or more per year ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
