APPARATUS AND METHOD FOR FLUID MONITORING
Abstract
According to some embodiments, an apparatus and method are provided for detecting the composition of a fluid. An alternating electromagnetic field may be applied to the fluid and distortions in the electromagnetic field are compared with predetermined, expected distortion «signatures» for particular components at particular concentrations. The presence and concentration of the components in the fluid may be detected by detecting these distortion signatures.

DETERMINATION OF ATTRIBUTES OF LIQUID SUBSTANCES
Abstract
A monitoring unit (100) that determines parameters (p1, p2) of an attribute (P) of a liquid substance flowing (F) through a dielectric conduit (110) includes plural coil members (121, 122) encircling the dielectric conduit (110) that subjects a flow of the liquid substance to plural different electromagnetic fields (B(f)), and under influence thereof measuring circuitry registers corresponding impedance measures (z(f)) of the liquid substance. A processor (130) derives the parameters (p1, p2) of the attribute (P) based on the registered impedance measures (z(f)).

VIVO DETERMINATION OF ACIDITY LEVELS
Abstract
A bolus for use in a ruminant animal’s reticulum includes a cavity (100) configured to receive ruminal fluids present in the stomach. The cavity has walls (110) of a dielectric material and is encircled by a coil member (120), which is configured to subject the ruminal fluids to an electro-magnetic field. A Sensor element (310) measures the electromagnetic field’s influence on the ruminal fluids and thus register an electromagnetic property representative of an acidity level of said fluids. A transmitter (410) transmits a wireless output signal (SD) reflecting the acidity measure.

Testing apparatus for simulating stratified
or dispersed flow
Abstract
A system and method for simulating stratified or dispersed flow dynamics are disclosed herein. The method includes filling an apparatus with a multi-phase mixture that includes an upper phase and a lower phase, wherein the upper phase and the lower phase are immiscible liquids. The method also includes establishing contact between a bottom surface of a rotor drum and a top surface of the upper phase. The method also includes rotating the rotor drum such that the rotation of the rotor drum causes the upper phase to rotate and ultimately causes the lower phrase to also rotate. The method further includes monitoring a parameter of the multi-phase system while the rotor drum is rotating.

Sensor for detecting liquid spilling
Abstract
Present invention concerns generally to a sensor or a sensor system for detecting spilling of aqueous liquids, for instance in confined spaces were such is critical such in an airplane. The system of present invention is an early warning system or sentinel for the prevention of corrosion by corrosive liquids. Corrosion caused by corrosive liquids can rapidly change the surface properties of components in engineering structures, and that will finally endanger the functionality of structural parts. However, if monitoring technologies are in place providing continuous information on the presence of corrosive liquids, corrosion treatment and even corrosion prevention can start at a very early stage. Present invention provides such by early detection of corrosive liquids by extended sensors based on the collapse of percolation conductivity (COPC). The term collapse refers to the fact that the transition into the non-conducting state must not necessarily have the properties of a thermodynamically well-defined transition.
