8.6.3 Entering the K factor of the fitting used
The device determines the flow rate in 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. “8.6.4”.
The device will use the new K factor as soon as "SAVE YES" is confirmed when leaving the Parameters
menu.
The K factor of the fitting used is in 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.

8.6.4 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. “8.6.3”.
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.
