Abstract

An actuating counter for use in conjunction with a fluid metering device, such as a liquid displacement meter, which can be preset prior to commencement of operation to count out a desired number of product units characterized in that upon actuation of the preset mechanism, further manual operation of the preset mechanism is precluded by an interlock mechanism which is equally adaptable to existing and newly manufactured counters, yet which can be aborted at any time in an emergency.
