Operating and functions
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 display shows the K factor of the
fitting, may it have been entered or
determined by a teach-in procedure; this
K factor is currently used by the device
→ Edit the parameter.
K-FACtOR K=10.000
REtURN
→ Enter the K factor (value between 0,0001
and 9999,9) of the fitting used.
→ Confirm the displayed value.
K=2.8500
OUtPUt VALiD N/Y
Is only displayed if the K factor has been changed.
→ Confirm the entered K factor or not.

→ If you do not want to adjust another parameter, go to the "END" parameter of the Parameters menu and press
ENTER
to save the settings or not and go back to the Process level.
8.6.4. Determining the fitting K factor using a teach-in procedure
Before any teach-in procedure, do the following:
• Calibrate the flow zero point of the device. See chap. 8.7.2.
• Check that the Kw coefficient of the sensor has not been disturbed. See chap. 8.7.4.
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 pro-
cedure. 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 that has been measured with a reference device.
