摘要： The invention relates to a method and an arrangement for an ultrasound clamp-on flow measurement according to the transit-time method. The problem addressed by the invention is to provide a measurement arrangement for clamp-on flow measurement, which enables measurement using only two pairs of acoustic transducers in both reflection configuration and in X configuration, without requiring the acoustic transducer position to be changed when switching between configurations. For the method according to the invention, at least four acoustic transducers are arranged on a measurement pipe, which are controlled in such a way that the flow measurement is performed consecutively in an alternating manner in the X configuration and in the reflection configuration. For this purpose, two acoustic transducers are connected for each transmission-receiving pair for a flow measurement in X configuration, and/or two acoustic transducers are connected for each transmission-receiving pair for two reflection configurations.

摘要： Apparatus and methods described herein provide for boundary layer flow sensor and corresponding determination of the flow characteristics of an ambient airflow over an aerodynamic surface. According to one aspect of the disclosure provided herein, the boundary layer flow sensor includes a body configured for mounting within or below the aerodynamic surface, a pressure port configurable between an open state for taking pressure measurements within the boundary layer of the ambient airflow and a closed state that protects the pressure port from contaminants when not in use.

摘要： Disclosed is a method and device for testing wind speed. The method includes, but is not limited to: measuring a static pressure P0 of an inner cavity of a pressure hole of a mobile device (S100), wherein the pressure hole being in communication with the outside; aligning the pressure hole to a wind direction and acquiring a total pressure P of the wind (S101); and acquiring a current wind speed according to a corresponding relational expression between a wind speed v and a dynamic pressure P−P0 (S102). The device includes, but is not limited to, a pressure sensor and a wind speed acquiring unit. The technical solution acquires the current wind speed according to a correspondence between wind speeds and dynamic pressures of wind, may effectively improve the precision of the wind speed testing, and does not cause damage to relevant parts of the mobile device.

摘要： Sensors for air flow, temperature, pressure, and humidity are integrated onto a single semiconductor die within a miniaturized Venturi chamber to provide a microelectronic semiconductor-based environmental multi-sensor module that includes an air flow meter. One or more such multi-sensor modules can be used as building blocks in dedicated application-specific integrated circuits (ASICs) for use in environmental control appliances that rely on measurements of air flow. Furthermore, the sensor module can be built on top of existing circuitry that can be used to process signals from the sensors. By integrating the Venturi chamber with accompanying environmental sensors, correction factors can be obtained and applied to compensate for temporal humidity fluctuations and spatial temperature variation using the Venturi apparatus.

摘要： An adjustable height pressure sensing port arrangement is provided. In some example, the pressure sensing port may be arranged on an airfoil, such as wind turbine blade. The pressure sensing port arrangement may include a pressure sensing port body and a spring arranged within the port body. The pressure sensing port arrangement may further include a pressure sensing port arranged vertically above the spring and a rotatable capture disk arranged vertically above the port. The capture disk may be rotated to adjust a height of the capture disk. Further, the spring may be arranged to force an alignment feature of the pressure sensing port into an alignment feature on the rotatable capture disk in order to secure the port and capture disk in place.

摘要： A blade-mounted total pressure (BMTP) probe for a rotor blade comprises a base segment and an inlet segment. The base segment includes an interface surface having a planar configuration that is complementary to an aerodynamic surface of the rotor blade for detachably mounting the BMTP probe in combination with the rotor blade, an aerodynamically-streamlined body member contiguous with the interface surface that includes a leading edge and first and second flow surfaces, and a fluid communication aperture extending through the aerodynamically-streamlined body member and the interface surface. The inlet segment comprises an inlet defined by a lower wall contiguous with the aerodynamically-streamlined member, opposed sidewalls contiguous with the lower wall, and an upper wall contiguous with the opposed sidewalls. The inlet segment further includes a backwall contiguous with the lower wall, the opposed sidewalls, and the upper wall and wherein the backwall, the lower wall, the opposed sidewalls, and the said upper wall in combination define a collection chamber within the inlet segment. A fluid communication aperture extends through the lower wall in aligned relation with the fluid communication aperture of the base segment. An ejection port is formed through the one opposed sidewall distal from the center of rotation of the main rotor blade.
