Connect the bang that is your pulse to both inlets of timer.  What timer will output is the number of milliseconds between beats.

Next, type this in an object box: !/ 60000

Connect the output of timer to the input of that box. That will output BPM.  Why? Because there are 60000 milliseconds in a minute, 60000/ms-per-beat = beats per minute.

good luck,
