  • A Standard for Users and Manufacturers of Thermal Dispersion Mass Flow Meters
    Thermal dispersion mass flowmeters comprise a family of instruments for the measurement of the total mass flow rate of a fluid, primarily gases, flowing through closed conduits.
  • Fine Powder Design - Flow Rate Control (.pdf)
    Engineers must often control the mass flow rate from a handling system by using a volumetric feed device. This poses several problems. Accurate control requires three conditions: consistent bulk density, geometries that are not flow rate limited, and orifice sizes greater than cohesive hang-up
  • Introducing a New Paradigm for Thermal Dispersion Mass Flow
    groundbreaking innovations in sensor design. That, along with a comprehensive algorithm facilitated by current hyper-fast microprocessors, has created a new paradigm for the measurement of the mass flow rate of gases by means of thermal dispersion technology.
  • Advances in Thermal Dispersion: Mass Flow Meter Accuracy (.pdf)
    to generate a. signal directly proportional to the temperature differential and mass flow rate. Over the years, Thermal type flow sensors have. been utilized across a very wide spectrum of applications and feature an assortment of performance limits. Modern Thermal flow sensor designs have greatly evolved

  • Mass Flow Meters
    (R) mass flow meter line uses the science of particle acceleration and its resultant forces to measure flow rate and total weight at accuracies of +/- 0.5%. Space efficiency and overall reliability make Multicor (R) an ideal choice for feeding, measuring and batching applications involving
  • Principle of Mass Flow Instruments: Measuring Unit of Flow Rate
    A mass flow meter measures the mass flow irrespective of pressure and temperature. When representing mass by the flow, it is necessary to use units such as g/min and kg/min which are different from the familiar units used for general fluid measurement. Therefore, it is common to use volume fl ow
  • Choked flow doesn't need theHeimlich maneuver
    Manipulating the principles of choked flow can simplify valve design. Flow rate versus upstream pressure for a 0.005-in.-diameter orifice. When upstream pressure is lower than 27.84 psia, the curve is no longer perfectly linear. Most mass-flow controllers are thermal based. That is, they use
  • Application Note: Quantified Leak Rate Using Mass Flow
    Production and test engineers often know the leak rate of product in bubbles per minute, but do not have an accurate way to convert bubbles to more universal ? ow numbers such as cubic centimeters per minute.
  • Thermal Mass Flow Meter Improves Refinery Flare Gas Monitoring Accuracy
    toxic gases. This gas mixture led them to conclude that mass (rather than volumetric) flow rate was the most important parameter to consider in the incineration process and to assist in plant's mass balance calculation. In the header lines, the variable flow rate ranged from just 0.5 to 150 SCFM
