Introduction to the LI-710
The LI-710 Evapotranspiration Sensor measures the total transport of water from
evaporation and transpiration over an area using automated eddy covariance flux cal-
culations. The output from the LI-710 is evapotranspiration, energy flux, and other
parameters in 30-minute increments. It uses the SDI-12 protocol to transfer data to
an external data recorder.
Figure 1-1. The LI-710 Evapotranspiration Sensor consists of two transducers for anem-
ometric measurements and an air intake.
