摘要： An apparatus and method for the measurement of, for example, the moisture in a material or, more generally, for the measurement of any material parameter which may be inferred by measuring the electromagnetic properties of the material under investigation. The meter apparatus comprises a controllable source of electromagnetic energy having stable selectable frequency. The controllable source of electromagnetic energy is coupled to a material measurement chamber by means of probes, loops, antennas, apertures or other structures so as to establish an electromagnetic field inside the measurement chamber thereby causing the field to interact with the material contained in the chamber. The method includes passing the process material through a frequency sensitive measurement cell. Exposing the process material to electromagnetic energy produced by a multi-frequency source. Generating an output signal having a distinctive frequency response characteristic. Detecting and amplifying an output signal by a receiving means and converting the signal to a digital representation. Analyzing the digital representation of the signal by the computer to determine the cutoff frequency. Determining the sharpness of the cutoff characteristic by mathematical algorithms in the computer. From the measured cutoff frequency and the sharpness of the cutoff characteristic, determining the dielectric constant and the conductivity of the material. Using stored calibration data or equations in the computer, computing and displaying the desired material property, e.g., the material's moisture content. And further, using the passband attenuation to determine the density of the material.

摘要： The present invention provides an apparatus and method for the measurement of, for example, the moisture in a material or, more generally, for the measurement of any material parameter which may be inferred by measuring the electromagnetic properties of the material under investigation. The electromagnetic properties of use in the present invention are complex electrical permittivity or the magnetic permeability of the material. The meter apparatus of the present invention comprises a controllable source of electromagnetic energy having stable selectable frequency. The controllable source of electromagnetic energy is coupled to a material measurement chamber by means of probes, loops, antennas, apertures or other structures so as to establish an electromagnetic wave inside the measurement chamber thereby causing the wave to interact with the material contained in the chamber. Its preferred structure comprises coupling of microwave energy from a coaxial transmission line to the measurement chamber over a multi-octave bandwidth via an intermediate microstrip to slotline coupling circuit.

摘要： A device is provided for detecting the ullage level and flow in a vessel by detecting the presence of a solid or liquid material in proximity to a microwave detector. The device may be mounted to the side of the vessel or suspended inside the vessel so as to bring the microwave sensor into proximity with the surface of the contents of the vessel. A microwave bridge circuit may be used to detect a change in either the amplitude or phase of a signal reflected by the material within the vessel compared to a reference signal tuned to either the presence or absence of the anticipated solid or liquid material. In one embodiment, the reflected material signal is compared to the signal from a sample chamber containing the material to be detected. The device can reliably detect the level of multiple interfaces for various materials having distinct electric or magnetic properties.

摘要： A sweep frequency, continuous wave (CW) radar tank gauge (3) providing measurement of the level of tank contents or ullage (19), having greatly improved accuracy through improved methods of processing calibrate and return signals directed toward the surface of tank contents (20). Use of sweep synchronous measurement (46) of time domain calibrate/return difference signals (42) and time domain of a virtual "carrier" fundamental in the frequency domain, provide highly accurate measure of tank signal return times. The entire range of return signals is made available for processing and analysis (5), including distinguishable tank bottom reflections.

摘要： A microwave apparatus and method for ullage measurement of agitated materials is provided. The apparatus and method utilize a transformation of the reflected time domain signal into a frequency domain signal. The frequency domain signal is averaged using the natural, inherent weighting associated with the transformation to achieve a unique corrected result. The average frequency domain signal is then used to calculate the average distance for determining the ullage measurement.
