9.7.3 entering the K factor of the fitting used
The device determines the quantity of fluid that flows through the pipe using the fitting K factor.
The K factor of the fitting used can be entered here. The device may also determine the K factor using a teach-in
procedure: see chap. “9.7.4”.
The device uses the new K factor as soon as "SAVE YES" is confirmed when leaving the Parameters
menu.
The K factor of the fitting used can be found within the operating instructions of the fitting.
The operating instructions of the Bürkert fittings can be found on the CD delivered with the device or on
the internet at
www.burkert.com .
The display shows the K factor
of the fitting, last entered or
determined using a Teach-In
procedure.

ENTER to save the settings or not and go back to the Process level.
9.7.4 Determining the fitting K factor using a teach-in procedure
The device determines the flow rate in the pipe using the fitting K factor.
The "TEACH V." or "TEACH F." parameter allows the device to determine the fitting K factor using a Teach-In
procedure. The K factor may also be directly entered: see chap. “9.7.3”.
The teach-in can be done either depending on a known volume ("TEACH V.") or depending on the flow rate
("TEACH F.") in the pipe, measured by a reference instrument.
Determining the fitting k factor using a teach-in procedure depending on a volume ("teAch v.")
• Before starting the Teach-In procedure, connect a valve to the relay output DO2.
• The device uses the new K factor as soon as "SAVE YES" is confirmed when leaving the Parameters
menu.
