| 20090260424 | SELF-CHECKING ANALYZER METHOD AND SYSTEM USING FREQUENCY RESPONSE - A self-checking analyzer system is provided according to an embodiment of this disclosure. The analyzer system includes a pipeline for receiving a multi-phase fluid flow and a first measuring device configured to provide a first frequency response corresponding to the multi-phase fluid flow. The analyzer system also includes a second measuring device differing in frequency response from the first measuring device and configured to provide a second frequency response corresponding to the multi-phase fluid flow. The analyzer system is configured to validate the first frequency response using the second frequency response. | 10-22-2009 |
| 20100242578 | Method and Device for the Production of a Polycrystalline Ceramic Film on a Substrate Capacitive Structure Comprising Said Ceramic Film and Use of Said Capacitive Structure - In a method for production of a polycrystalline ceramic film on a substrate: a) the substrate is prepared with the substrate surface and preparation of at least one source for the ceramic particles of the ceramic film and b) a particle stream of the ceramic particles is generated from the source of ceramic particles in the direction of the substrate surface on the substrate, with deposition of the ceramic particles on the substrate surface on the substrate with formation of the ceramic film. At least one screen is arranged within the gap, for adjusting an average incidence angle of the ceramic particles relative to a plane normal of the substrate surface, such that the ceramic particles are deposited on the substrate surface at a preferred direction and a relative position of the substrate surface and the screen is altered whilst the gap remains essentially the same. | 09-30-2010 |

| 20120055239 | MULTIPHASE FLUID CHARACTERIZATION SYSTEM - A measurement system and method for permitting multiple independent measurements of several physical parameters of multiphase fluids flowing through pipes are described. Multiple acoustic transducers are placed in acoustic communication with or attached to the outside surface of a section of existing spool (metal pipe), typically less than 3 feet in length, for noninvasive measurements. Sound speed, sound attenuation, fluid density, fluid flow, container wall resonance characteristics, and Doppler measurements for gas volume fraction may be measured simultaneously by the system. Temperature measurements are made using a temperature sensor for oil-cut correction. | 03-08-2012 |

The sensor can also further comprise an analyte delivery system and can be functionalized for detection of at least one analyte. | 07-03-2014 |
| 20140238115 | CLAMP-ON-TYPE ULTRASONIC CONCENTRATION METERING SYSTEM AND METHOD - Disclosed is a clamp-on-type ultrasonic concentration metering system and method. The clamp-on-type ultrasonic concentration metering system includes an ultrasonic sensor portion and a concentration meter. The ultrasonic sensor portion is attached to an outer wall of a pipe through which a fluid to be measured flows and that transmits and receives an ultrasonic signal through a wall of the pipe. The concentration meter measures a concentration of a substance according an intensity of the ultrasonic signal that is received after passing through the wall of the pipe, the fluid to be measured, and the wall of the pipe by means of the ultrasonic sensor portion. | 08-28-2014 |
| 20140238116 | ULTRASONIC SYSTEM FOR MEASURING BOTH FLOW RATE AND CONCENTRATION - Disclosed is an ultrasonic system for measuring both a flow rate and a concentration including: a transmission ultrasonic sensor which is attached to an outer wall of a pipe and which transmits an ultrasonic signal, a concentration-metering ultrasonic sensor which is attached to the opposite outer wall of the pipe and receives the ultrasonic signal that has passed through the wall of the pipe, flow-metering sensors which are attached to the opposite wall of the pipe and receive ultrasonic signals transmitted by the transmission ultrasonic sensor at different points in time, and a unified signal processor which measures a concentration and a total amount of suspended solids according to the intensities of the ultrasonic signals received by the sensors, and measures a flow rate of a fluid using a difference in transit time through a medium. | 08-28-2014 |
