  • Patent number: 10295387
    Abstract: A fluid-flow measuring ball valve includes a housing and a ball having an orifice. The ball is moved between an open position allowing fluid flow through the orifice and a closed position preventing fluid flow. A first ultrasonic transducer is positioned in the housing upstream of the ball. A second ultrasonic transducer is positioned in the housing downstream of the ball and both are aligned to send and receive pulses. First and second acoustic reflectors are aligned with the transducers to transmit and reflect ultrasonic signals in at least one direction through the ball orifice when the ball is in an open position. The controller determines the fluid velocity based on measured speed of sound and calculates the volume of fluid through the orifice based on the measured fluid velocity and cross-sectional area.

  • Patent number: 10280025
    Abstract: A sensor controller for web handling applications is described. The sensor controller is provided with a first port, a second port, a computer readable medium, and a processor. The first port receives a sequence of data frames capturing an area of a material web having a width to height ratio between 0.10 and 100. The computer readable medium stores logic indicative of identifying properties of a first group of data points of a feature of the material web extending in a web direction of travel. The processor scans the sequence of data frames to locate a transition between a property of the first group of data points and a property of a second group of data points in the data frames and generates a series of location signals indicative of lateral locations of the transition within the data frames. The second port outputs the location signals.

  • Patent number: 10281310
    Abstract: Several embodiments include a method of computing a phase composition ratio of a two-phase mixture in a pipe. For example, the phase composition ratio is a void fraction or a dryness fraction. The two-phase mixture can have one or more material substances that do not travel as a whole (e.g., at least two of solid phase, liquid phase, and gaseous phase or two liquid materials of different densities that do not mix). A load cell can measure, continuously, weight of the pipe and content of the pipe. Then, a computing system or a circuit can compute, continuously, a moving average of the continuously measured weight. The computing system or the circuit can compute a change in the phase composition ratio of the two-phase mixture based on the computed moving average.
