14. Speed
SPEED averaging serves to smooth out fl uctuations in the fl ow rate that may be caused by inadequate straight pipe runs after pumps,
valves, and elbows in the pipe. The selections are 0, 7, 15, 30, 60 and 120 seconds. The factory standard setting is 30 seconds.
• Use faster (0 s -30 s) averaging for well-established, stable fl ow conditions.
• Use slower (60 s -120 s) averaging if the fl ow conditions are unstable.
Note:
While the SPEED setting helps to smooth out the fl uctuations caused by piping conditions, it also causes a delay in showing
actual changes in fl ow rate. The SENSITIVITY function (section 15) is designed to help offset this effect.
Example: Change the SPEED setting from 60 seconds to 30 seconds.
