US Patent:

53214080, Jun 14, 1994

Filed:

Dec 31, 1992

Appl. No.:

7/999680

Inventors:

Buford R. Jean - Round Rock TX
Gary L. Warren - Austin TX

Assignee:

Baker Hughes Incorporated

International Classification:

G01S 1308

US Classification:

342124

Abstract:

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.

Filed:

May 30, 1991

Appl. No.:

7/707742

Inventors:

Buford R. Jean - Round Rock TX
Gary L. Warren - Round Rock TX
Richard W. Newton - Dallas TX
Billy V. Clark - Dallas TX

International Classification:

G01F 2328
G01R 2706

US Classification:

73290V

Abstract:

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.

International Classification:

G01N 2204
G01R 2704

US Classification:

324639

Abstract:

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.
