Thus, a momentary switch closure takes place with each tip of the bucket. Connecting the sensor to an event counter on an electronic datalogger or display module will allow record keeping of accumulated rainfall. If an analog signal representing rainfall accumulation is required, Texas Electronics, Inc. manufactures a suitable conditioning circuit.

PROPER EXPOSURE OF METEOROLOGICAL INSTRUMENTS Generally recognized guidelines follow which depict "ideal" sensor mounting locations. These guidelines or "rules of thumb" are only suggestive in nature in an attempt to aid the user to selecting optimum representative sampling locations for a particular sensor. Reference was made to US Weather Bureau Installation criteria in preparing this data (See Reference 1).
Roof-mounting of rain gauges should be avoided when possible. Air currents at heights other than at ground level have been observed to cause an apparent decrease in rainfall catch commensurate with the increase in mounting height above ground level. Objects which individually or in small groups constitute a "windbreak" reduce prevailing wind speed in the vicinity of the gauge.

Additional cable lengths are available from Texas Electronics if needed. Step 12: Calibrate the Wind Vane.
Page 19
Two methods of aligning the vane are available. The first method involves loosening the large set screw at the bottom of the wind direction sensor so that it will rotate on the U-arm. Turn the bottom half of the sensor until the compass readings and the indication match then retighten the set screw.
