3.1.5

Documentation

For every measuring spot you should:

measure the installation spot from 2 reference points (A must for
installations below the ground surface).

Take documenting photos before, during and after installation.

Save a soil sample.

Write down installation depth and angle with each sensor
identification (serial number).

Mark all connecting cables with the corresponding sensor
identification, serial number or logger channel on each end. Clip-
on number rings are available as an accessory.
3.1.6

Selecting the installation angle

An installation position would be ideal if the typical water flow is not
disturbed by the Tensiometer. No preferential water flow along the
shaft should be created.
If the ceramic cup is positioned higher than the sensor body the first
bubble that may appear inside the shaft will block the water
exchange and stop the Tensiometer to measure.
