For pseudo-homogeneous flows, measurements of density and mean velocity can give the
component mass flow rate of a two-component mixture. However, for accurate measurement …

Laser absorption spectroscopy has been a valuable technique for sensitive, non-intrusive, in-
situ detection of gaseous and liquid phase target species. The infrared spectral region is …

The main disadvantage associated with the use of impedance devices for measuring
volume fraction in multiphase flows is that they are sensitive to the distribution of the phases …

Recent developments in the principle of using in situ electrical sensing methods to
interrogate the behaviour of concentrated dispersions and suspensions are described …

Rod position measurement sensor is the key equipment of control rod hydraulic drive line,
the measurement accuracy of the sensor is directly related to the safety and reliability of the …

Permanent downhole multi-phase monitoring (DMM) can give several advantages in field
development, such as increased flexibility in the development of multi-lateral and horizontal …

This paper presents a novel and contactless water fraction (also known as water cut)
