  • 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 ...

  • 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 ...

  • Non-contacting solution for Plugged off flow meters in the oil patch - Case Study

    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 ...

  • 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 ...
