摘要: A weather station with at least one element mounted on bearings on a housing or rack on a vertical axis for alignment with the direction of the wind and with a measuring device, which depending on the angle position of the element aligning in the direction of the wind provides an electrical signal, wherein the measuring device is an opto electric measuring device with at least two light paths. Each of the at least two light paths has its own light-emitting element and which have a common light detector and form a light path configuration, each light path is used to scan a group of markings, which are located around an axis of at least one screen in such a manner that the markings provide a code when scanning that defines the angle area of the position of the element aligning with the direction of the wind. The light-emitting elements determine the angle position of the element aligning with the direction of the wind.

摘要: A portable hand-held vane anemometer is disclosed in which a modular vane assembly is removably mounted within the casing of the instrument. Within the modular vane assembly is a rotatably mounted impeller shaft. The impeller assembly preferably can be removed and inserted into a cavity of the anemometer. Consequently, if the impeller, bearings or other components of the impeller assembly should become damaged, the modular impeller assembly can be quickly and easily replaced. The vane anemometer of this invention may also measure temperature dependent environmental parameters and may also have the ability to measure these parameters relatively quickly and accurately when moving from one thermal mass to another thermal mass. These environmental parameters may include ambient temperature, wind chill, humidity and heat index. In order to determine these parameters, the vane anemometer may have a temperature probe and a humidity sensor that are disposed external to the casing. Preferably, the temperature probe and the humidity sensor are thermally isolated from the casing, so that each can respond relatively quickly when moved from one thermal mass to another. The probe and the sensor may also be disposed within one or more openings defined in the casing of the anemometer. The openings are sized large enough so as to permit enough air flow around the probe and the sensors to obtain quick and accurate readings, and small enough so as to protect the probe and the sensor from damage from mechanical forces.

The vane anemometer of this invention may also measure the temperature and the wind chill of the ambient air. In order to accurately and quickly measure these parameters the vane anemometer may have a temperature probe that is disposed external to the casing of the anemometer. Preferably, the casing has an opening defined by a plurality of walls of the casing in which the temperature probe is disposed. The temperature probe may be coupled to a microprocessor by an electrical connector that extends from the casing.

摘要: The flow meter has in a substantially cylindrical inner housing (1) a helically designed diffuser (4), which imparts a swirl to the medium flowing through the inner housing. Downstream of the diffuser there is rotatably mounted a rotor (8), which has blades (13) extending from its rotational spindle (9) as well as a ring (14) which connects the blade ends to one another and is coaxial to the spindle. The rotor (8) is set in rotation by impingement of the blades (13) by the flowing medium. On the outer circumferential surface (15) of the ring (11) there is on a circular line a multiplicity of markings (16) arranged at equal angular intervals from one another. Through a window (18) in the inner housing (1), a light beam strikes the outer circumferential surface (15) of the ring (14), provided with the markings (16). Upon rotation of the rotor (8), the sequence of markings is transmitted by an optical-fibre cable (20) and sensed by a sensor (21), so that from the signals received the flow rate can be determined. The flow meter has the advantage that the medium to be measured does not have to be transparent as in the application of the light barrier and that the multiplicity of markings allows an increase in the measuring accuracy.

摘要: A through-hull speed sensor of the magnetized paddlewheel sensor type wherein a paddlewheel is rotatably supported in a cavity adjacent a magnetic sensing device which generates electrical pulses corresponding to paddlewheel speed as the wheel rotates when the vessel moves through water. The sensor has improved low speed characteristics provided by a housing which extends the paddlewheel into the water below the hull. The bow of the housing provides a new leading edge, generating a smaller thickness boundary layer at the paddlewheel, so that the paddles project beyond the layer at low speeds. High speed performance is improved by having a high ratio of paddle fore-to-aft drag coefficient shape; keeping the periphery of the paddlewheel hub within, or flush with, the bottom of the cavity; a low paddle projection versus paddlewheel radius ratio; and by keeping the ratio of paddle cross-section versus available cavity cross-sectional space within an optimum range.

摘要: A wind speed and wind direction signal generator includes first and second pulse signal generators each with a respective stator and rotor. The stator for each pulse generator has at least two stator coils mounted at a radial angle relative to each other in the direction of rotation of a rotor so that pulse signals excited on the stationary output lines of the two stator coils are phase shifted relative to each other at a phase detectable angle. The rotor has at least one permanent magnet with two poles spaced from each other for rotation relative to the respective stator coils and for exciting the pulse signals on the stator coil stationary output lines. First and second wind propellers are secured to the respective rotors and are oriented to compass directions at approximately 90.degree. defining a quadrant of a compass coordinate system. The wind propellers cause rotation of the respective rotors at respective frequencies proportional to first and second wind speed components. Phase detectors detect the direction of phase shift of pulse signals from each pair of stator coils from the first and second pulse signal generators. Counters count the pulses from the respective signals over predetermined time intervals generating wind speed component magnitude signals. A microprocessor and program elements compute the desired wind speed and wind direction information from the wind speed component magnitude signals, wind direction angle signals, quadrant signals, calibration factor signals, and trigonometric function signals.

摘要: An optical fiber/paddle wheel fluid velocity sensor is provided which has application as a boat speed sensor and a fluid flow meter as well as other applications. The paddle wheel may be of integral construction and incorporates a plurality of T-shaped paddle blades which are disposed in some substantially parallel, spaced relation with an axial shaft portion thereof. Each of the blades is inclined and offset with respect to the axis of rotation. Each of the paddle blade elements includes a signal interrupter projection capable of passing between closely spaced aligned optical fibers to thus interrupt the light signal therebetween and provide for multiple direct digital signal pulses that may be electronically processed to represent the velocity of fluid flow.
