Application and mode of operation
Precipitation meters as well as rain gauges serve for a simple detection of precipitation.
Precipitation striking the surface of the earth in the form of rain, snow, drizzle, sleet, hail etc. is collected by the precipitation
meter.
There is a sharp-edged ring on the upper part of the meter which has a collecting area of 200 cm². The precipitation which
has been collected is led off into the tank to prevent it from evaporating, etc. The measuring cylinder, which is included in
the shipment, serves for the simple detection of precipitation height by metering in litres . The measuring cylinder is graduated in mm precipitation volume.
All it takes for environmental research

Mounting and operation
The instrument should be set up at a site whose distance from neighbouring
buildings or trees is equal to the height of these objects. It should be free towards the side facing the weather.
Attach the complete rain gauge with the enclosed holder (3) to a pole. The
pole should be skewed at the top to prevent erroneous measurement data
resulting from spray water.
When the instrument has been mounted, the collecting ring of the rain gauge
should be situated approximately 10 cm above the tip of the pole. The collecting
surface should be 1 m above the ground. Now place the instrument in the holder
(3) making sure that the container (4) has been inserted into the lower part (1).
To measure the amount of precipitation, remove the upper part (2) and pour
the precipitation, which has been gathered, from the tank (4) into the measuring cylinder (5).
The precipitation can be read in mm precipitation height at the scale of the
measuring cylinder.
To measure snow with the rain gauge, insert a snow cross into the upper part
(2) of the rain gauge. This prevents the snow from blowing away. Then simply
remove the rain and snow gauge together with the precipitation which has
been gathered once a day, replace it with the second instrument (upper part,
lower part, snow cross, and tank). Allow the collected precipitation to melt in
a moderately warm room.
After the melting the upper part is removed for the measurement, and the
melting water is poured from the tank into the measuring cylinder.
The precipitation can be read in mm precipitation height at the scale of the
measuring cylinder.

A precipitation height of 1 mm corresponds to a water volume
of 1 liter on 1 m² ground surface.
