  • 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 ...

  • Attenuation of an ultrasonic beam by suspended particles and range of acoustic flow meters in sewer networks

    Ultrasonic flow meters are commonly used in wastewater management. Under certain circumstances, a reduction in the flow meter range may occur and cause significant error in the flow rate measurement. Attenuation due to suspended particles is one of the phenomena capable of reducing the flow meter range. The present paper examines attenuation resulting from re-suspended pond sediment over a wide ...

  • 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 ...

  • Non-Contacting Solution for Plugged Off Flow Meters in The Oil Patch

    For years Petrobakken Energy Ltd. used inline turbine flow meters to track the flow rate of oil recycled to treaters. But with a high concentration of wax and sand in the oil, the turbine meters were quickly plugging off. The line had to be shut down at least once a day and the turbine flowmeters disassembled for cleaning. This was troublesome and expensive. Petrobakken knew there had to be a ...

  • Open Channel Flow - The use of Level sensors for open channel flow measurement

    Open Channel Flow - The use of Level sensors for open channel flow measurement Level sensors from SolidAT are implemented in Open Channel Flow applications. In these types of applications, the level sensor is installed above a special water flow structure and accurately measures level of flowing water or wastewater. The sensor then calculates flow through the structure ...

  • Two Technologies for Flow Measurement from Outside a Pipe

    Doppler and Transit Time are two very popular types of flow meter for non-invasive measurement of flow in full pipes. We tend to confuse these technologies because they are both ultrasonic and both measure flow by using sensors clamped onto the outside of a pipe. In the real world they actually work best in opposite applications. Success in your installation depends on understanding the ...
