Chart Recorder



A chart recorder can be installed In both the suction and discharge piping to give you an accurate picture of the pump’s head over a period of time.

Gages show the head only at the moment you are looking at them. The head can vary during the day because of:

  • Changes in valve positions.
  • The emptying and filling of tanks.
  • Changes in the pump’s speed.

You need this differential head information to determine if the pump is running somewhere near its best efficiency point (BEP.)
