9:30 am Sap Flow Theory SFM1 Sap Flow Meter and the HFD8 Multipoint Radial Profiling Sap Flow Meter. A detailed explanation of the Heat Ratio Method & HFD principles covering instrument design, temperature rise, ratio’s, needle spacings, effect of diurnal stem temperature, anatomy of trees, thermal diffusivity, wound correction, radial sap velocity gradients, circumferential heterogeneity, converting sap velocity to, sap flux density and sap flow, gravimetric validation of Heat Ratio Method, hydraulic redistribution, sap flow in roots.

10:30 am Morning Tea

10:45 am Practical 1 – Configuring the SFM1 & HFD8 Sap Flow Meters Participants will use a laptop and Combined Instrument Software (CIS) to directly interface via a USB cable and wireless radio Modems (MCC-Mini) to configure SFM1 & HFD8 Sap Flow Meters. Learning key features of successful installation of sap flow meters including; heat pulse criteria, measurement interval, measurement mode (when to use Sap Flow mode in raw heat pulse velocity and when to use raw needle temperature mode), power requirement calculations, using solar panels, using external batteries, using external batteries in conjunction with solar charging. Battery management, instrument cleaning & storage.

1:00 pm – Lunch

1:30 pm Practical 2 – Installation of the SFM1 & HFD8 Sap Flow Meters Participants will form groups of two people to install Sap Flow Meters where they will learn the following installation techniques: Tree selection, stem site selection, Site preparation, tree parameterisation (determination of stem diameter, bark depth, sap wood depth, positioning of inner and outer measurement points, use of spacers), Drilling technique (how to achieve a parallel installation), use of sleeves, safe removal of instruments without damage to needles.

4:15 pm – Afternoon Tea

4:30 pm – Practical 3- Remotely accessing Sap Flow DataParticipants will use DATAVIEW-web software to remotely access Sap Flow data access via the cloud.

5:30 pm – End of Day’s formal activities

Enabling better global research outcomes in soil, plant & environmental monitoring.

Day 2

9:00 am – Review of Sap Flow Data using DATAVIEW Web remotely via cloud Participants will remotely access the Sap Flow Meters installed the previous day and review the quality of their installations assessing asymmetry of installation, examples of good data versus bad. What to look for in sap flow data such as asymmetry of installation, wounding and how this differs from physiological response, zero flow and reverse flow.

9:30 am – Theory & Practice of Soil Moisture Measurement A detailed explanation of the full range of principles & instrumentation to measure soil moisture will be presented. Insights into analysing and interpreting soil moisture content and movement using depth graphs and time series data to reveal principles such as Full and Refill points that have revolutionised the global irrigation industry over 4 decades.

10:45 am – Morning Tea

11:00 am – Theory of Stem Psychrometry A detailed explanation of psychrometry theory covering, instrument design, principle of measurement (Peltier Cooling), current cooling duration, psychrometric plateau – Psychrometric Wet Bulb Depression, Temperature correction, independent validation of principle, using empirical illustrations of water potential components such as gravity and osmotic potential. And how non-destructive and continuous measurement of water status can be used to identify physiological phenomenon in the field such as apparent stomatal closure.

12:00 am – Practical 4 - Configuring the PSY1 Stem Psychrometer Participants will use a laptop and Participants will use a laptop to directly interface via a USB cable and wireless radio Modems (MCC-Mini) to configure PSY1 Stem Psychrometer. Learning the key features of successful in-situ psychrometry such as why, when and how to use chamber heating, reverse Peltier Thermocouple heating, and calibration of the psychrometer.

1:00 pm – Lunch

1:30 pm – Practical 5 – Installing the PSY1 Stem Psychrometer Participants will learn the following installation techniques: (i) site preparation and Installation of a stem psychrometer using conventional razor blade site preparation on a 25 to 50 mm stem or lateral branch; (ii) Forstner Bit installation on large diameter stems; (iii) site prep and installation on leaves using both a Stem Psychrometer and Leaf psychrometer chamber (iv) good insulation technique

2:30 pm - Practical 6 – Verifying the PSY1 against a Scholander Pressure Chamber Participants will destructively sample leaves adjacent to their psychrometer installations and independently measure the water status of the leaves for direct comparison to the non-destructive measurement of xylem water status of the plant measured by the PSY1 Stem Psychrometer

3:30 pm – Afternoon Tea

3:45 pm – Participants to Share Experiences in Applications Participants with data sets to show and discuss.

5:00 pm – End of Day’s formal activities

5:30pm Possible BBQ - Dinner & Social Event



Day 3

09:00 PSY1 Data Review Participants will remotely access the Stem Psychrometers & Sap Flow Meters previously installed and review the quality of their installations using remote data access via the cloud. Participants will be on the lookout for condensation, insufficient insulation, and plant environment interaction.

09:30 ICT International Wireless Instrumentation Platform Overview An overview of the architecture and capabilities of the ICT Wireless platform will be presented. This will establish the background to the possible applications that ICT Instrumentation can offer that will be performed in the subsequent practical session.

10:00 - Practical 7 – Configuring the ICT International SDI-12 Datalogger Following a brief introduction, participants will configure an SDI-12 logger with a diversity of instruments based around broad applications - soil, water, light and meteorology.

10:45 am - Morning Tea

11:30 pm Wireless Signal Surveying for Network Scoping and Design Introduction to the ICT International Wireless Survey Kit. Exploring network planning, potential signal constraints within a network and conducting theoretical and active signal surveys.

12:00 pm ICT Universal Telemetry Hub Configuration and Networking From the box to the mast, setting up an ICT telemetry hub for data collection. Includes an overview of the ICT CIS Customer Account Management Utility, testing GSM signal and logger networking and synchronisation.

12:30 pm – Practical 8 - Wireless signal surveying Participants will conduct wireless signal survey using the ICT International Wireless Survey Kit. This practical will demonstrate the methodology of wireless signal surveying and highlight the extent to which topographic and vegetative features constrain signal propagation.
