In running production the measurement of process and material properties in-line, is a
requirement to design and implement effective process control in injection moulding. This …

Ultrasonics. A subject with applications across all the basic sciences, engineering, medicine,
and oceanography, yet even the broader topic of acoustics is now rarely offered at …

The analysis of chemical species is one of the most fundamental and long-standing
challenges in fiber-optic sensors research. Existing sensor architectures require a spatial …

In ultrasonic pulse-echo systems, polymers like PMMA (polymethylmethacrylate) and PEEK
(polyetheretherketone) are often used as buffer-rods, placed between the ultrasound …

In this contribution, an overview is given of physical sensors for the determination and
monitoring of the state of liquids. Basic liquid properties in different energy domains …

Optical fibers are an excellent sensor platform. However, the detection and analysis of
media outside the cladding and coating of standard fibers represent a long-standing …

In this article review of density and viscosity measurement methods is presented, including
ultrasonic pulse echo methods, which are capable to measure these properties of polymer …

The accuracy of density, reflection coefficient, and acoustic impedance determination via
multiple reflection method was validated experimentally. The ternary system water–maltose …
