From 30 years experience:
Reading oscillograph pulsation "signature", to identify the causes.
Recognizing normal activity, and deciding how smooth it needs to be.

Graphics, interpreting pressure over time oscillograph traces,
to identify the sources of shock and pulsation.

1. Suction starvation time lag.
2. Foot valve oscillation.
3. Typical acoustic response, tells nothing more than the length of the supply pipe.
4. Channel "cavitation", from high velocity and 4:1 delta P.
5. Vortex frequencies - meter disturbance inaccuracy.
6. Normal pump start-up.
