A mini-spinner flowmeter (1) is intended for use in a hydrocarbon well (101) for measuring a fluid linear velocity and/or a fluid direction (F1, F2) of a fluid (100) present in the hydrocarbon well (101). It comprises an impeller (2) formed with a plurality of axially extending vanes (3) longitudinally secured to a shaft (4), the shaft (4) extending along a longitudinal axis (XX), the impeller (2) being caused to rotate at an impeller angular velocity depending on the fluid linear velocity and in a rotational direction (Rt1, Rt2) depending on the fluid direction (F1, F2); and a support (5) having a bearing (6, 7) positioned on each end of the shaft (4) and a through-hole (8) securing an optical section (9). The optical section (9) comprises an emitting optical fiber (E), a first receiving optical fiber (R1) and a second receiving optical fiber (R2), optical fiber distal ends (10) directed towards the vanes (3) defining an optical path (11) offset from the shaft longitudinal axis (XX) and positioned such as to face a vane rotation trajectory. The vanes (3) are reflective such that, in use, a light energy (IE) emitted by the emitting optical fiber (E) and reflected backward by anyone of the vanes (3) is received by the first receiving optical fiber (R1) and/or the second receiving optical fiber (R2), the reflected light energy (IR) containing information indicative of the fluid linear velocity and/or the fluid direction (F1, F2).

A measurement device includes a frame member rotatably supported about a first axis line, a detection body disposed inside of the frame member and rotatably supported relative to the frame member about a second axis line, and a vane disposed on one end side of the detection body in a direction orthogonal to the second axis line and that directs the other end side of the detection body in the direction orthogonal to the second axis line toward an air flow upstream side upon receiving an air flow. The measurement device includes a wind direction sensor disposed in the detection body that detects a wind direction as a direction of the other end side of the detection body in the direction orthogonal to the second axis line, and a wind speed sensor disposed in the detection body that detects a wind speed of the air flow.

A flow of air induces vibration of a tip of an airflow sensor. A cantilever coupled to the tip vibrates as the tip is displaced, and a piezoelectric element associated with the cantilever generates an electrical signal in response to mechanical stress or strain induced by vibration of the cantilever. A control element that is in communication with the piezoelectric element of the cantilever receives the electrical signal and derives at least one parameter indicative of the flow of air sensed by the sensor. The control element communicates or otherwise transmits an output signal that is indicative of the parameter to an output device to display sensor data to a user as desired.

A machine is disclosed for wind sensing on sailboats. Wind is important for sailing, but sailboats lean away from the wind when under sail. Vertical wind angles reduce the accuracy of existing anemometers. The cup blades disclosed here do not lose rotation speed when heeling over. Since it is now easy to have a sophisticated chartplotter display on a mobile device in waterproof case even on small boats, this waterproof wind sensor is a wireless appcessory that can talk to smartphones, tablets, computers, e-readers and marine electronics. The circuit board is encapsulated and is itself the wind direction arrow. A fluxgate compass on the circuit board provides wind direction. The apparatus is solar-powered, so there is no wiring to install or chafe. This allows a further inventive step for raising the anemometer using the mast track without needing to climb up or lower the mast.
