Fisher & Porter rain gauge

A weighing-recording rain gauge that mechanically converts the depth of accumulated precipitation during a given period of time to a code disk position.

The code disk position is recorded on punched paper tape at selected intervals. The time interval of recording is 15 minutes and the accumulated precipitation is read to the nearest 2.5 mm (0.10 in.). The gauge can be modified for remote transmission.
