Met-One 014A Wind Speed Sensor

1. General

The 014A is a three-cup anemometer that is used to measure horizontal wind speed. Rotation of the cup wheel opens and closes a reed switch at a rate proportional to wind speed.
The accompanying Met One manual contains additional information on operating principals, installation, and maintenance.
Lead length for the 014A is specified when the sensor is ordered. Table 1-1 gives the recommended lead length for mounting the sensor at the top of the tripod/tower with a 019ALU or CM200 series crossarm.
TABLE 1-1. Recommended Lead Lengths
CM6 CM10 CM110 CM115 CM120 UT10 UT20 UT30
11’ 14’ 14’ 19’ 24’ 14’ 24’ 37’
The 014A ships with:
(1) Calibration Sheet (1) Instruction Manual (1) 014ACBL-L Sensor Cable w/user specified length

2. Specifications

Threshold 0.45 m/s (1 mph) Calibrated Range 0-45 m/s (0-100 mph) Gust Survival 0-53 m/s (0-120 mph) Accuracy 1.5% or .11 m/s (0.25 mph) Temperature Range -50 C to +70 C Distance Constant* Standard: Less than 4.6m (15 ft.) (Aluminum Cups) Optional Fast Response: Less than 1.5 m (5 ft.) (Lexan Cups) Output Signal Contact Closure, Reed Switch Weight 680 grams (1.5 lbs)
* The distance traveled by the air after a sharp-edged gust has occurred for the
anemometer to reach 63% of the new speed.

NOTE
The black outer jacket of the cable is Santoprene compound was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.

3. Installation

3.1 Siting

Locate wind sensors away from obstructions (e.g. trees and building). As a general rule of thumb there should be a horizontal distance of at least ten times the height of the obstruction between the windset and the obstruction. If it is necessary to mount the sensors on the roof of a building, the height of the sensors, above the roof, should be at least 1.5 times the height of the building. See Section 8 for a list of references that discuss siting wind speed and direction sensors.

3.2 Assembly and Mounting

Tools Required:
1/2” open end wrench
5/64” Allen wrench
compass and declination angle for the site
small screw driver provided with datalogger
UV resistant cable ties
small pair of diagonal-cutting pliers
6 - 10” torpedo level
Mount the 019ALU or CM200 series crossarm to the tripod or tower. Orient the crossarm north-south, with the 3/4” Nu-Rail or CM220 on the north end.
Insert the base of the 014A into the Nu-Rail or CM220 (Figures 3-1, 3-2) and tighten the set screws on the Nu-Rail, or U-bolts on the CM220 (do not over tighten).
Attach the sensor cable to the connector on the 014A. Make sure the connector is properly keyed, and finger-tighten the knurled ring. Route the sensor cable along the underside of the crossarm to the tripod/tower, and to the instrument enclosure. Secure the cable to the crossarm and tripod/tower using cable ties.

Connections to Campbell Scientific dataloggers are given in Table 4-1. When Short Cut for Windows software is used to create the datalogger program, the sensor should be wired to the channels shown on the wiring diagram created by Short Cut.
