    Abstract: An ultrasonic meter includes a group of piezoelectronic ceramic arrays, wherein each array comprises array stripes, such that a signal associated with each array can be split and a required phase shaft added to the signal to obtain simultaneously different data from the signal such as, for example, the transit time of a direct path and crosstalk. The smaller array can provide a higher aperture and improve the use of crosstalk.

    Abstract: A system, method, and apparatus for reducing ringing effects associated with a transducer comprises a transducer body, a transducer cap, a piezoelectric element formed in the cap, and a damping material formed around the piezoelectric element wherein the damping material suppresses a ringing effect associated with the transducer, while an O-ring is used together with damping material to support high pressure applications up to 230 bars.

    Abstract: A method and system for locating and quantifying fugitive gas emission leaks includes obtaining gas sensor data and wind direction data from a plurality of sensors and weather stations located proximate a given area of interest. The gas sensor data and the wind direction data is validated to remove erroneous values and to merge the gas sensor data with the wind direction data to provide time synchronized gas sensor data and wind direction data over a given time interval. The time synchronized gas sensor data and wind direction data is segmented for each gas sensor location into wind direction bins containing a concentration of the gas levels in each bin. The area of interest is divided into a grid of cells and the bins projected on the grid cells for each gas sensor location along with the level of gas contained in the bins. The grid cells are then grouped into one or more contiguous grid cells having gas levels above a predefined level and a boundary area is calculated containing the grid cells with a gas level above a threshold to identify a potential leak area. The potential leak area is matched with a prior calculated leak area to identify the source location of the emission leak.

    Abstract: A system includes at least one pressure sensor that is configured to generate a first signal in response to sensing a process and generate a second signal in response to sensing a drift detection condition different from the process. The system includes at least one processing device that is configured to determine a pressure measurement (Pprocess) of the process using the first signal, and determine a pressure measurement (AP2) of the drift detection condition using the second signal. The at least one processing device is configured to compare the pressure measurement of the drift detection condition to one of: the pressure measurement of the process or a reference value. The at least one processing device is configured to identify whether drift has deteriorated accuracy of the at least one pressure sensor based on the comparison.
