A wind sensor has a housing and a wind detection element, which is rotatably mounted on the housing and is formed by a wind wheel having a cup-star including a plurality of cups, wherein at least one ohmic heating element is incorporated in the wind wheel. Structures are provided for transferring energy between the housing and the ohmic heating element rotating with the wind wheel. The structures can include a primary coil arranged in the housing and a secondary coil arranged in the wind wheel, wherein the secondary coil is connected to the ohmic heating element. The plurality of cups of the wind wheel are each mounted by way of flat webs, wherein the webs extend into the cups and divide the cups into two regions, and the at least one heating element is embedded in the webs and extends into the region of the cups.

Improvements are disclosed here for a sailboat wind sensor (PCT/CA2014/000416) in which the solar panels form the tail of the wind direction arrow, and a digital compass is built into the wind direction arrow. The battery is moved to the nose cone and held in waterproof container to serve as a counter-weight, eliminating the brass nose cone which is traditionally used on anemometers to substantially reduce the weight. A new method of encapsulating the electronics in the tail is disclosed, using ultrasonic welding of a shell over the circuit board, rather than molding a resin over the electronics.

A mini-spinner flowmeter measures a fluid linear velocity and/or a fluid direction of a fluid present in a hydrocarbon well. It comprises an impeller formed with a plurality of axially extending vanes longitudinally secured to a shaft, the shaft extending along a longitudinal axis, the impeller being caused to rotate at an impeller angular velocity depending on the fluid linear velocity and in a rotational direction depending on the fluid direction; and a support having a bearing positioned on each end of the shaft and a through-hole securing an optical section. The vanes are reflective such that, in use, a light energy emitted by an emitting optical fiber and reflected backward by anyone of the vanes is received by a first receiving optical fiber and/or a second receiving optical fiber, the reflected light energy containing information indicative of the fluid linear velocity and/or the fluid direction.

A weather sensing system mountable on a tubular member. The weather sensing system includes a weather sensor housing including removably attached first and second housing portions. The first housing portion includes a first open channel and the second housing portion including a second open channel aligned with and opening toward the first open channel. The first and second open channels form an enclosed channel for receiving and fixing the weather sensing system to the tubular member.
