摘要： A sensor assembly for use in synchronizing seed placement and the dispensing of liquid agricultural product during planting. The sensor assembly includes a signal conditioning circuit configured to provide an output signal representing an indication of the presence of liquid agricultural product and seed for use in determining the synchronization of the seed placement with the dispensing of the liquid agricultural product. The presence of both a seed mass component and a liquid mass component of the output signal defines a package mass. The output signal has a pre-defined value and is transmitted to a controller to determine whether there is an error. The controller is configured to generate an error signal that is capable of being displayable on a remote display/user interface system that can be monitored by the system operator.

摘要： An ultrasonic measurement system for measuring a flow in a conduit. Spaced ultrasonic signal transmitters are configured to launch a ultrasonic beams having a center axis of maximum intensity. Receiving transducers are configured to receive modulated signal energy from the beams and are located off the center axis of the beams to increase the modulation of the signal energy and to produce receiver output signals. A processing subsystem is configured to correlate the receiver output signals to determine a time delay indicative of the flow velocity in the conduit.

摘要： An opto-mechanical anemometer is particularly adapted to measure fluctuations in the flow of a turbulent fluid such as can be applied in the measurement of wind turbulence for meteorological purposes, the turbulent flow of fluid through a pipe or conduit, or the flow of air through a tube from the breath of a patient for medical diagnostics. An optical fiber is positioned in the flow path of the fluid and fixed motionless at one end. The free end is caused to bend in response to fluctuations in the flow. A beam of light is projected out the free end of the optical fiber toward a stationary optical detector placed in the path of the beam, which is sensitive to the point of maximum intensity of the beam of light. Deflection of the optical fiber translates into movement of the light beam over the detector, allowing measurement of the speed and direction of the fluid flow in two orthogonal planes.
摘要翻译：光机械风速计特别适用于测量湍流流动的波动，例如可用于气象目的的风湍流测量，通过管道或管道的流体的湍流或通过的空气流来自患者呼吸的管用于医疗诊断。光纤位于流体的流动路径中，并在一端固定不动。使自由端响应于流动的波动而弯曲。光束从光纤的自由端朝向放置在光束路径中的固定光学检测器突出，该光束对光束的最大强度点敏感。光纤的偏转意味着光束在检测器上的移动，允许在两个正交平面中测量流体流的速度和方向。
