  • How Does a Water Flow Meter Work?

    A water flow meter is a device that measures the amount of water flowing through a pipe. There are several water flow meter technologies to choose from depending on the water measurement application, maintenance requirements, and budgetary terms.  Each of these types of water flow meters has a unique principle of operation, specific application benefits, and overall ...

  • Five principles of uncertainty for modelers discussed in November-December issue of Groundwater

    If you’re a member of the NGWA Scientists and Engineers Section, you will soon receive your copy of the November-December 2017 of Groundwater®, an issue brimming with a wide range of topics. In his Guest Editorial, Randall J. Hunt offers five principles of uncertainty for groundwater modelers. He argues that uncertainty must ...

  • How Does a Water Flow Meter Work?

    A flow meter works by measuring the amount of a gas, liquid or steam that passes through or around the flow meter sensors. While flow meter sensors work in many different ways, the end goal is the same: Deliver the most accurate and repeatable flow measurements for the specific application, whether for general research, process control or semiconductor processing. Flow meters measure either mass ...

  • Integrating toxicity reduction strategies for materials and components into product design: A case study on utility meters

    Using RIO Tronics utility meter products as an industrial case study, the numeric Fraunhofer Toxic Potential Indicator (TPI) assessment tool is employed to determine high impact materials with the aim of reducing the content of inherently toxic substances in these products. However, because product re‐design with alternative materials affects entire components, overall component toxicity ...

  • New Developments in Thermal Dispersion Mass Flow Meters: In-The-Field Compensation for Changes in Natural Gas Composition

    Introduction The flow of natural gas in pipelines is often complicated by changes in the composition of the gas. The method described in this paper solves the problem of variable composition via a new four-temperature mass flow sensor. The new (low sensor feeds its measurements into the algorithms of an advanced mathematical model that includes gas properties in its calculations. The method ...

  • REDmeters - Blue Paper

    REDmeters: Abstract The process of controlling and the cost of monitoring slurries in many industries are normally accomplished using various continuous mass flow systems. These types of systems usually contain a magnetic flow meter and a line density meter. There is inherent cost associated to these systems due to the inaccurate nature of these meters. Some meters on the market boast up to ...

  • Measurement of glucose nanoparticles concentration in plasma and blood accurately using laser sheet interferometry

    Diabetes is one of the major diseases in Egypt and perhaps all over the world. Diabetic patients suffer from many acute and chronic symptoms and diseases which may lead to blindness, reduced blood circulation in extremities arising ulcers and gangrenes. In this paper, we present a new technique called the laser sheet interference technique developed by the first author, for measuring the optical ...

  • Modeling of radial well lateral screens using 1D finite elements

    A water supply system including radial wells (RWs) is usually large, extending several tens of kilometers horizontally and is dozens of meters deep. An RW is a vertical shaft with lateral screens, which radially penetrate the soil. A large and complex 3D finite element (FE) mesh also needs to include laterals with cross-sectional dimensions measured in centimeters. An adequate representation of ...

  • Dewatering Crews Keep the Alameda Corridor Dry and Open for Business

    Griffin installed a multitude of deep wells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter high density polyethylene pipe (HDPE) to a below grade mixing vault, where a neutralizing agent was introduced to the groundwater as the quality of the groundwater was not allowed to discharge to the designated receiving ...

  • Effect of sodium azide on the metabolic activity of cultured fetal cells

    Sodium azide is a highly toxic substance. However, the mechanism of its toxicity has not been fully established. In the present study, we attempted to investigate the toxicity of sodium azide in various cultured fetal cells, using changes in cellular respiration as an indicator of metabolic inhibition to elucidate tissue-specificity. The human fetal cell lines used in this study included ...
