Short summary
Turbulent fluxes are usually measured by the eddy covariance method using a combination of a costly gas analyser and a sonic anemometer. In this paper we present an eddy covariance set-up of low cost to measure evapotranspiration over agricultural fields. The method is shown to be comparable to a conventional eddy covariance set-up and is a viable alternative when spatial replicates are required.
