A Direct Method for Estimating the Average Sap Flux Density Using a Modified Granier Measuring System
- Aust. J. Plant Physiol., 24, p.701-705, 1997 .
The Granier sap flow measuring system that normally uses one analogue input channel of a datalogger for each sensor was modified to enable one channel to measure the average value of signals from two or more sensors. The sap flux density calculated from this average value of signals was very close (difference < 6.0
