Fischer & Porter punch traffic counter recorder: an electro-mechanical counter which coverts input pulses to angular positions on a rotating shaft by means of a stepping motor which are converted to successive positions of memory code disks. There by means of a clock mechanism the punch programming system initiates the punch demand and establishes the various punching and reset operations required for recording stored values on a 16 track data recording tape. It is designed for portable use and is powered by an internal 7.5 volt dry battery.
This counter was purchased (c.1965) by the City Engineer’s Department of Edinburgh Corporation and was used to count traffic at a number of locations in the city and possibly elsewhere in Lothian Region. They were replaced by Stevens counters.
