Anemometer

Anemometer information The Anemometer is constructed using a high quality ball bearing, stainless steel hardware, UV stable plastic, and durable anodized aluminum hemispherical cups that are weight matched. The Anemometer’s wiring is protected inside a PVC pipe which allows for easy mounting using a 50 mm (2”) pipe clip or similar. The only moving part on the anemometer is a ball bearing that typically lasts 3 years in high winds or 10+ years in less extreme areas. Assembly of the anemometer: 1) Push the PVC pipe into the top and then base section – making sure wiring doesn’t get trapped between the pipes.
Beware of trapping wires
2) Connect the jack plug from one end of the 10 m lead to the socket in the base of the Anemometer. 3) Connect the jack plug at the other end of the lead to the jack socket on the side of the Smart Q Count/Tachometer adapter. 4) Select the range of the Count/Tachometer adapter as Wind speed either in metres per second or miles per hour.
Specifications: Performance Accuracy: 0.45 m/s (1 mph) when operating at between 5 to 25 m/s (11 to 55 mph) Starting speed: 1 m/s or 2 mph Output Signal Sensor Type: Reed switch, dry contact. Frequency proportional to cup rotational speed. Transfer Function: m/s = (Hz * 0.786) + 0.948; mph = (Hz * 1.758) + 2.121 Physical Properties of Anemometer

Mounting instructions: An anemometer should be mounted so it is in free flowing air. There are several ways to mount an anemometer and you need to determine which is the best based on your situation. Keep these considerations in mind: Find a location where wind flow will not be obstructed by tall buildings or trees. Mount the anemometer as far away from any obstacle as is practical. Objects such as fences will slow the wind and cause reduced readings. If mounting on a roof an anemometer should have 4 feet of clearance above the roof line to avoid any aerodynamic effect that may affect the reading. There is a risk of lightning strike damage with any anemometer. Data Harvest will not be liable for any damage arising from use in these circumstances. Avoid mounting the anemometer on an active chimney as the corrosive fumes and heat may damage the sensor. Jack plug connection The Anemometer is supplied with a 10 m lead ending with two 3.5 mm stereo jack plugs. The lead maybe lengthened by using a 3.5 mm male/female jack extension cable.
