LeWL stand alone wind speed data logger - No need for a computer to log data, it is completely a completely stand alone system.
The LeWL stand alone wind speed logger comprises of two digital channels of contact closure from an anemometer, an analogue channel for measuring wind direction from a potentiometer style vane and a built in temperature sensor.
The unit is fully configurable to select between one or two simultaneous anemometer readings with changeable conversion factor to calculate wind speed. The wind direction readings are temporally stored in 16 bins (i.e.: NNW, SSE) and the one with major number of incidences is stored.
LeWL Wind Speed logger records the wind speed data with a date and time stamp per record. The file generated is fully PC compatible. Just insert the memory card into a memory card reader and access the data with your favourite spreadsheet application.

LeWL can also monitor:
Power and Energy performance from a wind turbine
Log energy used at home or office
Output data directly to a computer or display with a serial port
POWER & ENERGY PERFORMANCE
The LeWL can also be used to check performance and the power output of any wind turbine with the help of an export kWh meter. The SO output of the kWh meter can be connected to the second digital input and by changing its conversion factor; it can provide power or energy values.
Together with the wind sensors, this setup can be very useful to generate power curves of wind turbines.
TEMPERATURE
The LeWL has a temperature sensor built-in. This temperature sensor is able to measure temperatures from -40ºC to +125ºC. If more accurate readings were to be taken, the unit should be shielded from radiation.
SERIAL PORT RS232
The LeWL comes with a socket for serial port compatible with RS232 standards. This serial port is used to setup the LeWL and to connect to external displays or computers to access data collected in real time.
