Abstract: Apparatus including an electrically conductive housing, an electrically non-conducting pipe carrying the slurry through the housing, one or more primary coils each encircling the pipe within the housing and having a capacitor unit coupled thereto with a capacitor unit value chosen so that a primary coil series resonance is formed close to the value of a target magnetic resonance frequency, and for each primary coil, a drive coil and associated electrical network positioned to magnetically couple the drive coil to that primary coil. An impedance monitor coupled to each electrical network measures a complex input impedance thereof. An RF transmitter transmits a signal to one or more of the electrical networks with a frequency approximately equal to the target magnetic resonance frequency, and an RF receiver receives from each electrical network magnetic resonance signals from the target and forms an output signal of detected signals.

Abstract: Magnetic resonance (MR) apparatuses, systems and methods for analysing a material. The magnetic resonance apparatuses include a primary loop defining an aperture that the material being analysed can pass through where the primary loop includes at least one pair of electrically conductive segments. The magnetic resonance apparatus also includes a pair of capacitance units corresponding to each pair of electrically conductive segments. Each capacitance unit is conductively connected to two adjoining conductive segments in series so that the primary loop forms a circuit for a radio frequency (RF) current. The primary loop is adapted to: conduct the RF electrical current so that the RF electrical current is predominantly in-phase over the entire primary loop. The magnetic resonance apparatus further includes: a pair of secondary coils corresponding to each pair of capacitor units, electrically conductively isolated from the primary loop.

Abstract: There is disclosed a method of estimating moisture content in a material involving directing a first frequency (f1) signal and a second frequency (f2) signal through a material, determining a first absolute phase shift (?1) of the frequency signal and a second absolute phase shift (?2) of the second frequency signal, transforming ?1 to a first corrected absolute phase shift (?1c) and ?2 to a second corrected absolute phase shift (?2c) in accordance with an expected relationship between ?1 and ?2, and estimating moisture content from ?1c and ?2c.
