Flushing
NOTE: This procedure assumes that flushing connections have been made
to the TT100 Viscometer as defined in Section 2 - Installation.
NOTE: The solvent used for cleaning the viscometer is dependent upon the
process fluid being measured.
1. Refer to Section 4 - Operation and perform the Shutdown
procedure.
NOTE: If possible, isolate the section of pipe in which the viscometer is
installed from the main process system.
2. Drain the process fluid from the system or isolated section of pipe
in which the viscometer is installed.
NOTE: The time duration of step 3 varies by the amount of process fluid
build-up.
3. With the system drain valve open, open the flushing fluid valve and
allow the fluid to flow through the viscometer and out through the
drain valve.
4. Close the flushing fluid valve.
5. Close the process fluid system drain.
6. Refer to Section 4 - Operation and perform the Start-up procedure.
