摘要： A physical quantity measurement device that measures a physical quantity of a fluid has an inflow port and an outflow port, and includes a passage flow channel, a branch flow channel, and a physical quantity detector. An inner peripheral surface of the passage flow channel extends over a pair of facing surfaces, which face each other across the flow passage boundary portion and the inflow port on an upstream side of the flow channel boundary portion. The inner peripheral surface further includes an inflow step surface which forms a step facing the inflow port side.

摘要： A system includes sensors for monitoring pressure, flow, pump speed, temperature, and/or other signals at the output of a main hydraulic pump, and a processing system executes one or more methods for identification of hydraulic system events, from the signals, corresponding to state changes and performance of the system and/or its subcomponents. Event identification is performed with classification and/or other machine learning algorithms, with generation of novel training data sets. The sensor(s) can also be used to determine power consumption information about the system and/or its subcomponents. The system processes event-associated outputs for execution of actions for improving system performance, along with other downstream applications.

摘要： A flow rate detector includes: a housing; and a substrate assembly disposed in the housing. The substrate assembly has a flow rate detection element, a temperature detection element, and a circuit board on which the flow rate detection element and the temperature detection element are mounted. The circuit board includes a body portion fixed to the housing, and a protrusion extended to protrude from the body portion. The protrusion has an element fix portion to which the temperature detection element is fixed. The protrusion has a supported portion within a supported range including a position of the element fix portion. The supported range is defined from the element fix portion to a tip end of the protrusion along an extension direction of the protrusion. The supported portion is supported by the housing to suppress a displacement of the element fix portion in a thickness direction of the circuit board.

摘要： Apparatus and associated methods relate to measuring temperature of a fluid within a hydraulic vessel using a temperature probe that has an annular recess circumscribing a projecting sensor tip. The annular recess is configured to permit fluid flow into an aperture region of a vessel wall through which the temperature probe contacts the fluid within the hydraulic vessel. Because the temperature probe projects from the annular recess within the aperture, a net projection dimension, as measured in a projection direction from an interior surface of the vessel wall proximate the aperture to a sensor, is less than a gross projection dimension, as measured in the projection direction from a bottom of the annular recess to the sensor tip. In some embodiments, this configuration advantageously improves a ratio of thermal conductivity between the fluid and the temperature probe and thermal conductivity between the temperature probe and a sensor housing.

摘要： Systems and methods are provided for determining a temperature of a thermal system that includes fluid conduits. A sensor monitors a current state of the temperature. A controller receives a signal from the sensor that is representative of the current state; determines a flow in the fluid conduits; determines a noise covariance of the thermal system; processes a thermal model of the thermal system; predicts a next-step state of the parameter at a time after the current state; and corrects the next-step state based, at least in-part, on the noise covariance resulting in a corrected next-step state.

摘要： A bubbler device and method of its operation are disclosed. The bubbler device includes a bubbler tube that provides bubbles to a molten material in a furnace; a protective layer disposed on the bubbler tube; and a wire that is electrically coupled to the protective layer. The wire extends through the bore, and the protective layer and the wire partially form an electrical circuit for measuring integrity of the bubbler device based on at least one of conductivity or resistance in the electrical circuit. Sometimes, an inner protective material may be disposed on an inside surface of the tube and coupled to the protective layer, and the wire can be coupled to the inner protective material or multiple wires may be used. The use of dissimilar materials in these components may be used to form a thermocouple junction to measure the temperature of the molten material in a furnace.
