  • 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 ...

  • 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 ...

  • Advances in Thermal Dispersion Mass Flow Meters - Part 1 Principle of Operation

    Abstract This paper describes an advanced microprocessor-based thermal dispersion mass flow meter that uses four temperature sensing elements in its flow sensor instead of the traditional two elements and has a dry velocity sensor that uses no potting materials instead of the traditional potted velocity sensor. This unique new mass flow meter automatically manages changes in gas selection, ...

  • The POROLUX “calculated” First Bubble Point detection mode application note

    The POROLUX 1000 is a research grade capillary flow porometer with very pressure and flow control and accuracy. In the POROLUX 1000 a porous sample is inserted, wetted with a so-called wetting liquid. The sample is usually a flat round disk, three different diameters are standard: 13, 25 and 47 mm. Custom made sample holders are optional. The wetting liquid is a liquid which fills up all pores of ...
