A method for bubble volume measurement under constant flow conditions in gas–liquid two-phase flow

Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...

ROTAMASS 3 Series Coriolis Mass Flow and Density Meter - Achieving High - speed Measurement with High Accuracy and Robustness -

The Yokogawa Group has developed the ROTAMASS 3 series Coriolis flow and density meters. A Coriolis flowmeter can directly measure mass flow of fluid regardless of its temperature and pressure. The ROTAMASS 3 series meters have such unique features as fast signal processing, anti-vibration mechanism, and high accuracy density measurement. This paper describes these features and applications of ...

Thermal Flow Measurements at Gr/Re by Silicon Anemometry

We present the first characteristics of air flow measurements in the mixed convective region with strong buoyancy effects (Gr/Re 1), using a thermal silicon double-Wheatstonebridge vector sensor. The Alternating Direction Method is applied to eliminate additive drift influences. The upper limit on the mixed convective region is experimentally defined to be given by Gr/Re = [0:3–0:8]. Flow veloc...

Compensation of Verdet Constant Temperature Dependence by Crystal Core Temperature Measurement

Compensation of the temperature dependence of the Verdet constant in a polarimetric extrinsic Faraday sensor is of major importance for applying the magneto-optical effect to AC current measurements and magnetic field sensing. This paper presents a method for compensating the temperature effect on the Faraday rotation in a Bi12GeO20 crystal by sensing its optical activity effect on the polariza...
