  • How an Ultrasonic Flow Meter Works

    An ultrasonic flow meter utilizes ultrasound to measure the velocity of a fluid and is used in a variety of fluid applications. Ultrasonic flowmeters are ideal for water and other liquids. Clamp-on ultrasonic flow meters achieve high accuracy at low and high flows, save time with no pipe cutting or process shutdown, and are not affected by external noise. Here’s how ultrasonic flow ...

  • A Dutch first in the polder - Water Board Zuiderzeeland measures flow rates to achieve sustainability

    The Dutch province of Flevoland lies metres below sea-level. That’s why rain and seepage need to be removed from the polder, some 6 metres up. And that’s the reason Flevoland is drained continuously by seven huge pumping stations. The quantity of energy involved in this is as great as the energy consumption of 4,000 households. Water Board Zuiderzeeland has launched the ‘Energy ...

  • 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 ...

  • 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 ...

  • How Does a Thermal Flowmeter Work?

    A thermal flowmeter works by measuring the total mass flow rate of a fluid flowing through a pipe or duct. In a thermal flowmeter’s simplest working configuration, fluid flows past a heated thermal sensor and a temperature sensor. As the molecules of the fluid flow past the heated thermal sensor, heat is lost to the flowing fluid. The thermal sensor cools down while the temperature sensor ...

  • The Function of an Ultrasonic Flow Meter

    Running a water management operation requires taking a wide range of measurements. In addition to measuring the flow in your system, many systems must measure the water level of their channel, and one of the best tools for accomplishing this goal is an ultrasonic flow meter. ...

  • 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 ...

  • 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 ...

  • 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. ...

  • Strategies for the electric regulation of pressure control valves

    In water distribution networks (WDNs), the classic pressure control valves (PCVs) are mechanical/hydraulic devices aimed at maintaining the target pressure just downstream or upstream of the PCV pipe, namely pressure reduction or sustaining valves. From a modelling standpoint, the major drawback of such local control is that classic PCVs may require target pressure varying over time with the ...

  • What are the advantages of ultrasonic wind sensors?

    Whether mechanical, ultrasonic or laser wind measurements: All measuring methods have technical limits. While for mechanical wind sensors the measuring element – cups and vanes – itself predominantly produces a disturbance in the flow field, for ultrasonic anemometers a disturbance can be caused by the sensor holder or housing construction. Only optical methods, e.g. LDA (Laser ...
