What's the difference between pulsator and pulsatory?
Pulsator
Definition:
(n.) A beater; a striker.
(n.) That which beats or throbs in working.

(19) A mathematical model was derived expressing the amplitude of container pulsation (delta Po) as a function of mean intraluminal pressure (MPi), mean container pressure (MPo) and arterial pulse amplitude (delta Pi): delta Po = (-2(MPi - MPo) + b) (MPo + 1) delta Pi.
(20) Since it was easier to build equipment that recorded pulsations in amplitude, most work was confined to the recording of amplitude pulsations.
Pulsatory
Definition:
(a.) Capable of pulsating; throbbing.
Example Sentences:
