The Stevens annual snow and rain recorder

A description of a new automatic rain and snowfall record-gage is presented. (Shown in photograph). This instrument is designed to record a winter season catch of precipitation and print the resulting amounts on a graph. The receptacle has a capacity of 100 inches of precipitation either rain or snow. The receptacle is originally charged with a calcium chloride solution to prevent freezing and an oil film to prevent evaporation. The receptacle is balanced on a weighing frame and the weighing beam is kept in balance by a reversible motor that keeps the weighing ‘Paul’ constantly in balance. The weights are recorded on a weight driven ‘Stevens Type 30’ water-stage recorder. A wind motor provides current and charges batteries. The instrument is designed for isolated locations.
