Compatible with all Campbell Scientific dataloggers
Overview
The 014A, manufactured by Met One, is a three-cup anemometer that monitors wind speed for the range of 0 to 45 m/s with a threshold of 0.45 m/s. It connects directly to a Campbell Scientific datalogger, which measures the 014A's pulse signal and converts the signal to engineering units (mph, m/s, knots).

Benefits and Features
- Ideal for applications that do not require wind direction measurements
- Sealed magnetic reed switch
- Designed for continuous, long term, unattended operation in adverse conditions
- Standard aluminum cup assembly has a distance constant of less than 4.5 m
- For greater sensitivity, an optional LEXAN cup assembly has a distance constant of less than 1.5 m
The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description
The 014A is constructed of corrosion-resistant, stainless-steel and anodized aluminum. It's three-cup anemometer assembly contains a sealed magnetic reed switch. Rotation of the cupwheel produces a pulse that is directly proportional to wind speed.

Additional Compatibility Information
Mounting
The 014A attaches to a Campbell Scientific crossarm using a 1049 Nu-Rail fitting or CM220 Right Angle Mounting Bracket. It also can be attached to the top of our CM110, CM115, and CM120 stainless-steel tripods using the CM216 Sensor Mounting Kit.
Data Logger Considerations
The 014A uses one pulse count channel on the data logger.
Programming
The 014A is read by the PulseCount Instruction in CRBasic and by Instruction 3 (Pulse Count) in Edlog. Wind speed measurements can be taken and processed with any of the data loggers.

-
The CM240 fits the CS700-L, TB4-L, and the retired 385-L rain gages.
-
These rain gages don’t necessarily generate a voltage range, but rather a pulse. Depending on how the rain gage is connected to the data logger, the gage can generate a sourcing current or a sinking current pulse.
-
These high-end rain gages are used in applications where preservation of life is a priority, such as mine safety, dam safety, flood control, and slope stability.
-
These rain gages can be connected to either.
- When a control port is used, one lead goes to the 5 V port to provide current, and the other lead goes to a control port to detect the current.
- When a pulse channel is used, one lead goes to the pulse port, and the other lead terminates on a ground terminal.
-
The following are some suggestions to try:
- Check that there is a solid connection to the reed switch. The screws should be tight, and the wires should have a solid connection to the screws.
- Try switching the connection from the current reed switch being used to the secondary reed switch connection.
- Check that the cable is connected to the correct input on the data logger. Take the two wires on the other end of the cable (the sensor side) and touch them together. The data logger should register a tip. If the tip registers, the issue is with the reed switch. Replace the reed switch.
- If the data logger still doesn't register a tip, try using a different cable.
-
Not registering any tips, missing tips, or double tips.
-
If data is not being logged correctly, there are two likely causes:
- The reed switch has failed.
- There is a faulty connection from the rain gage to the data logger, typically caused by a broken conductor or corroded wiring.
-
Not enough tips or too many tips.
-
- Remove the housing assembly from the base by removing the three screws and lifting upward on the housing.
- Check the bubble level to verify the rain gage is level.
- Pour water through the inner funnel to wet the two bucket surfaces. Using a graduated cylinder, slowly pour 314 cc (19.16 in3) of water, over a 15 minute period, into the collection funnel. This volume of water is equal to 0.39 inches of rainfall (10 mm).
- After the water has passed through the rain gage, the tipping bucket should have tipped 39 times for the TB4-L or CS700-L, or 50 times for the TB4MM-L.
- If the rain gage fails to record the correct number of tips, return the unit to Campbell Scientific for recalibration.
-
The 260-953 Alter-type rain gage wind screen consists of 32 heavy metal leaves that hang freely and swing as the wind moves past them. The swinging leaves act as a wind damper and help minimize the effect of wind on the rain measurements without adding additional turbulence.
