TT100 In-Line Viscometer Installation, Operation, Maintenance and Service Instructions
P/N M/97-520 5-1
Section 5 - Maintenance
Introduction
There are three different methods for cleaning the internal components of
the TT100 Process Viscometer. The Clean-in-Place method, which is
typically used, provides minimal downtime and effective cleansing of the
viscometer during process system cleaning. The Flushing method is used
when additional internal viscometer cleansing is required. The
Disassembly and Cleaning method is used when the process system is
seriously contaminated and the viscometer cannot otherwise be cleaned.
Clean-In-Place
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: It may be preferable to 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.
3. Fill the system, or isolated section of pipe in which the viscometer
is installed, with cleaning fluid.
4. If equipped with a double mechanical seal assembly, apply the
barrier pressurized fluid pressure.
NOTE: The time duration of step 5 varies by the amount of process fluid
build-up and its cleaning characteristics.
5. Set the POWER switch on the Motor Control Enclosure to the ON
position. Allow the viscometer motor to operate until the
viscometer is clean.
6. Set the POWER switch on the Motor Control Enclosure to the OFF
position.
7. Drain the cleaning fluid from the system or isolated section of pipe
in which the viscometer is installed
8. Refer to Section 4 - Operation and perform the Start-up procedure.
