Abstract: A method of measuring the speed of a fluid comprising the following steps:
generating a plurality of pseudorandom frequencies (fus_n);
for each pseudorandom frequency (fus_n), emitting ultrasound signals into the fluid to travel along a path of defined length;
receiving the ultrasound signals;
for each received ultrasound signal, producing a travel time measurement, so as to generate for each pseudorandom frequency (fus_n) a predefined number of travel time measurements;
for each pseudorandom frequency (fus_n), evaluating the accuracy of the measurements;
for evaluating the speed of the fluid, making use of the measurements produced for the pseudorandom frequency that presents the greatest accuracy.-

Abstract: A flow meter records a flow rate and/or an amount of heat of a flowing fluid. A control and evaluation unit ascertains flow rate data and the fitting-dependent direction of through flow is automatically ascertained. A temperature measuring device has first and second temperature sensors for ascertaining a temperature difference between a feed temperature in the feed and a return temperature in the return. The fitting location of the first and second temperature sensors in the feed or the return is automatically ascertained by the control and evaluation unit on the basis of the temperature difference. The control and evaluation unit is automatically configured during first-time or re-installation of the flow meter such that the direction of flow through the meter is adapted to the fitted direction of through flow and/or the temperature sensors are assigned to the feed and the return, respectively.

Abstract: 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.

Abstract: 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.
