The present invention is a trap selector for selecting an optimum trap meeting various uses which is designed to sequentially input required data for selecting the trap and to execute previously memorized trapselecting programs by a microcomputer characterized in that the geometrical conditions of various kinds of traps are previously memorized, the thermodynamical working conditions such as pressure thereof are inputted, when an optimum trap must be selected, so as to calsulate the discharging flow rate (capacity), which is compared to the actually required discharging flow rate. In the conventional trap selector, all discharging characteristics for every pressure or temperature and the like of various kinds of traps must be memorized, but in the trap selector according to the present invention, the designated calculation is executed from the previously memorized geometrical conditions of various kinds of traps and the thermodynamical working conditions, which are inputted at the selection, such as pressure thereof and the obtained discharging flow rate is compared with actually required discharging flow rate and therefore the optimum trap can be decided.
