Campbell Scientific CS705 Tipping Bucket Snowfall Adapter - Manual (Page 7)

CS705 Snowfall Adapter
1. Introduction
The CS705 Snowfall Adapter converts a TE525WS Texas Electronics Rain
Gage to a rain and snow gage. It consists of an antifreeze reservoir, overflow
tube, and catch tube. Snow captured in the catch tube dissolves into the
antifreeze raising the overall level. The mixture flows through the overflow
tube into the tipping bucket where it is measured. A slot in the top of the
overflow tube prevents the tube from developing a siphon.
Before installing the CS705, please study
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 4, Quickstart
2. Cautionary Statements
• The CS705 possesses inherent delays and is not suitable for real-time
precipitation measurements (see Section 5, Overview).
• Since regular maintenance is required, choose a site that is easily
accessible throughout the winter.
• Wear safety glasses and rubber or neoprene gloves while handling and
pouring antifreeze.
• Campbell Scientific strongly recommends using antifreeze consisting of a
1:1 mixture of propylene glycol and ethanol (PGE). Appendix A provides
MSDS information for the PGE antifreeze offered by Campbell Scientific.
• Avoid using the antifreeze commonly used in cars or RVs. This
antifreeze, which consists of propylene glycol or ethylene glycol, increases
the likelihood of ice bridging (see Section 5.1, Antifreeze).
• The antifreeze/snowfall mixture needs to be captured from the tipping
bucket gage and properly disposed of in accordance with local, state, and
federal regulations.
• The CS705 should be removed and cleaned in the summer, and reinstalled
before the winter season.
