Parameter to be measured:
Rainfall
Method:
Tipping bucket raingauge
Equipment:
Raingauge: Davis
Logger: Hobo Event Logger
Advantages:
- Cheap
- Easy to install
- Logging of 8000 events possible
- Nice small logger in water tight pvc casing
Disadvantages:
- after two years the logger clock seemed to have some problems in some cases
Problems/Questions:
- the tipping bucket raingauge needs to be calibrated or the exact volume per event needs to be determined by dripping a specified amount of water into the raingauge and then deviding by the number of "events" measured. The volume per event is different for each gauge. (The difference from the specified 0.2mm can be significant!)
