  • Water Flow Monitoring Helps Avoid Costly Fines

    Water Distribution Company Refines Pumping System Many water distribution companies use a similar process for Water Flow Monitoring:  Collect water from a well with the help of water pumps, utilize a pond or reservoir to temporarily store the water and maintain a loading center to fill water trucks for transport. The problem is how to pump the maximum allowable volume of water on a ...

  • In-Situ Calibration - Methods & Pitfalls of Thermal Mass Flow Meter Sensor Field Validation

    Introduction Mid-to-large size facilities and campuses inevitably have hundreds of ¬ ow instruments to monitor, maintain, and repair. For a reliability engineer, ensuring that all instrumentation meets ISO 9000 or similar standards is a time-consuming responsibility. These standards mandate that precision instrumentation needs to be checked (validated) or recalibrated as often as once a ...

  • Sanitary Valve Installation

    1. Control valve seal design. The single seat valve can reach less than 1 drop per hour of leakage. The double seat valve is difficult to seal. Therefore, switching to a single seat valve must be an optional choice. 2. Large amounts of high pressure fluid trapped between the shut-off valves may present considerable force and ...

  • Understanding the iSeries Totalizer

    Do you have questions about the iSeries Totalizer App? We get many support questions regarding the app, generally covering the same few points, so let’s spend a few minutes and discuss how to use and understand the power of the iSeries Totalizer. What is a Totalizer Simply put, a totalizer is a running total of how much fluid (gas, liquid, steam) has passed by the ...

  • Hydraulic simulation of perforated pipe systems feeding vertical flow constructed wetlands

    For successfully operating a vertical flow constructed wetland, the uniform distribution of wastewater on the surface of the soil filter is essential. In research, however, this aspect is often overlooked. This study presents a methodology for assessing discharge uniformity from perforated pipe systems via hydraulic modeling. First, the requirements and conditions for the simulation of ...

  • The Safety Issues in Valve Installation

    In the design of the valve system, the following points need to be considered: 1. Control valve seal design. Single-seat valve can reach less than 1 drop per hour leakage. Double seat valve is difficult to close tightly. Therefore, the switching to a single seat valve must be an optional choice. 2. Large amounts of high-pressure fluid trapped between shut-off valves ...

  • 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 ...

  • Effect of Doppler flow meter position on discharge measurement in surcharged manholes

    Determining the proper installation location of flow meters is important for accurate measurement of discharge in sewer systems. In this study, flow field and flow regimes in two types of manholes under surcharged flow were investigated using a commercial computational fluid dynamics (CFD) code. The error in measuring the flow discharge using a Doppler flow meter (based on the velocity in a ...

  • Achievement Unlocked: Brian Estep Appointed Vice Chair of ASME’s Thermal Committee

    To solve problems and build solutions in the modern world, an engineer must have clear focus, an ability to think critically under pressure, and a willingness to work long hours. When skills are developed over time and knowledge is refined, meaningful innovation can and does come to fruition. However, what allows one to rise above day-to-day work to make a positive impact on the engineering ...

  • 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 ...

  • 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 ...
