Model HFP01SC Self-Calibrating Soil Heat Flux Plate

2 cm

6 cm

8 cm

Ground Surface

Up to 1 m

2.5 cm

Partial emplacement of the HFP01SC and the TCAV

sensors is shown for illustration purposes. All sensors

must be completely inserted into the soil face before

the hole is backfilled.

3. Installation

The HFP01SC Soil Heat Flux plates, the TCAV Averaging Soil Temperature

probes, and the CS616 Water Content Reflectometer are installed as shown in

Figure 1.

The location of the heat flux plates and thermocouples should be chosen to be

representative of the area under study. If the ground cover is extremely varied,

it may be necessary to have additional sensors to provide a valid spatial

average of soil heat flux.

Use a small shovel to make a vertical slice in the soil. Excavate the soil to one

side of the slice. Keep this soil intact so that is can be replaced with minimal

disruption.

The sensors are installed in the undisturbed face of the hole. Measure the

sensor depths from the top of the hole. With a small knife, make a horizontal

cut eight centimeters below the surface into the undisturbed face of the hole.

Insert the heat flux plate into the horizontal cut.

Install the HFP01SC in the soil such that the side with the text

“this side up” is facing the sky.
