Errata 1010FMA-61
2. DIN Pipe Table Note
In Section 2, add the following note right after paragraph 2.2.1 How to Select a Pipe Class:
NOTE:
The DN sizes listed in the [Select Pipe Size] menu option list are referenced to DIN Table
2448. After selecting pipe size, check pipe OD and wall thickness for correct dimensions.
3. Empty Pipe Set Procedure Update
In Section 2, paragraph 2.4.10 Empty Pipe Set Menu replace the introductory paragraphs and
warning with the following:
The flow meter performs the MTYmatic routine automatically during its Initial Make-up to estab-
lish a standard setting for the Empty Pipe alarm. This process is normally sufficient for setting
this parameter. The [Empty Pipe Set] option list allows you to re-invoke MTYmatic, use an
Actual MTY routine (if application conditions allow you to empty and refill the pipe) or use the
Set Empty routine to set the empty pipe threshold by direct numeric entry.
How To Use the Actual MTY Command
If application conditions allow you to empty and refill the pipe, then you may choose to perform
the Actual Empty procedure; however, it is not required to do so.
WARNING: NEVER perform the Actual MTY procedure if the pipe can not be emptied.
