  • 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 ...

  • 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 ...

  • Preventable Mistakes with Vortex Flow Meters

    Vortex flow meter technology is an ideal technology for many applications particularly saturated and supersaturated steam, volumetric water applications as well as flow energy management (natural gas, compressed air, steam, water) in facilities and large campuses. In some of these applications, vortex installations can be tricky and take flow expertise for the most successful installations. Kam ...

  • Why evaluate hydraulic fluid compatibility?

    When introducing a new control fluid to hydraulic systems, it is important to ensure that the new liquid or mixture is of equal or superior quality to the previous fluid. If the new mixture is incompatible, precipitate may form and result in an overall inferior fluid. This can speed up clogging or damage the system. When a manufacturer of construction machinery releases a new line of bulldozers ...

  • Flow Measurement in the Cold

    Measuring flow can be a very delicate process depending on the needs of your operation. For instance, measuring flow in cold weather locations is an extremely difficult task. When outdoor temperatures are near or below freezing, it makes it nearly impossible to measure flow as you would in normal circumstances, meaning you must find alternative solutions so that your operation continues to have ...

  • How Does a Water Flow Meter Work?

    A water flow meter works by measuring the amount of water that passes though the flow meter. The most common mechanical types work by measuring the speed of flowing water that causes a turbine or piston to rotate. The volumetric flow rate of the water is proportional to the rotational speed. Other water flow meters include ultrasonic, magnetic and vortex flow meters. The best type of water flow ...

  • Thurston County comments on Greyline Area-Velocity Flowmeters - Case Study

    We have been using Greyline products at Thurston County, Washington for approximately seven years. We use both the Stingray portable flow meters and the permanent Area Velocity Flow Meter (AVFM II) in multiple stormwater applications. We have used these meters to measure stormwater flows to help our design engineers develop flow capacity for stormwater projects. We have deployed the Stingrays at ...

  • Open Channel Flow Monitors retired after 16 years continuous service - Case Study

    Long Sault WWTP Influent Flow Monitors 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 ...

  • Area-Velocity Flowmeter Installations in Denmark - Case Study

    Area-Velocity Flow Meters are designed to monitor flow rates in partially filled pipes and open channels without flumes or weirs. A sealed ultrasonic sensor is mounted on the bottom of the pipe or channel and connected to electronics through a watertight cable. The sensor measures both level and velocity and when calibrated with the pipe diameter or channel dimensions, the Greyline AVFM ...

  • Irrigation Water Flow Measurement with Greyline AVFM Area-Velocity Flowmeter - Case Study

    The United Irrigation District (UID) in Southern Alberta, Canada serves 34,400 acres of rural land through a series of canals, channels and pipelines running 236 km throughout the region. Water is a valuable resource in the warm, arid regions of the province and agriculture uses 60-65% of the fresh water consumed. So water use is closely regulated and monitored. ...

  • Organic matter capture by a high-rate inoculum-chemostat and MBBR system

    The main objective of this study was to develop an innovative process to maximize the bio-transformation of colloidal and soluble biodegradable matter (CSB) into particulate matter (XB) for energy recovery via methane production. Two configurations were studied: (1) high-rate moving bed bioreactor (HR-MBBR) and (2) inoculum-chemostat (IC) system consisting of a very HR-MBBR inoculating a ...

  • Sound recording to characterize outdoor tap water use events

    Obtaining disaggregated water use at the home typically involves expensive smart metering. In this study, water use events at the outdoor tap were captured using recorded sound. Outdoor taps at 10 homes were fitted with small-sized microphones and digital sound recorders. Sound files recorded over a 1-month period were used in the analysis. In the preliminary analysis, a human operator browsed ...

  • The importance of groundwater monitoring

    Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

  • Effect of permanent magnetic field on scale inhibition property of circulating water

    Effect of a permanent magnet field on the scale inhibition property of circulating water was investigated. Orthogonal experiments of L16(45) were performed and analyzed using the range analysis method. The operating parameters included magnetic field intensity, initial concentration of Ca2+ and Mg2+, magnetic treatment time, temperature, and flow velocity. Scale ...

  • Building Box Culverts with Articulated Cable Concrete Block Systems

    When you need to manage the flow of water in an area with streams, heavy rainfall or otherwise consistently wet conditions, the box culvert stands the test of time. Box culverts have been around for many years for a good reason: they can be excellent tools for directing and controlling water so it doesn’t cause erosion and interfere with roads, trails or other manmade structures that need ...

  • Non-equilibrium model for solute transport in differently designed biofilters targeting agricultural drainage water

    Biogeochemical processes in subsurface flow constructed wetlands are influenced by flow direction, degree of saturation and influent loading position. This study presents a simulation tool, which aims to predict the performance of the unit and improve the design. The model was developed using the HYDRUS program, calibrated and verified on previously measured bromide (Br−) pulse tracer tests. ...

  • 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 ...

  • Report documents effects of 40 years of groundwater withdrawal

    The cumulative effects of 40 years of groundwater withdrawals in the Houston-Galveston region are documented in a report from the United States Geological Survey. Decades of extensive withdrawals have caused the land to sink, or subside. The Houston-Galveston region is one of the largest areas of land surface subsidence in the U.S., according to the agency. Water withdrawals started as early as ...
