Viscometer reading continu-
ously over 100% of scale.
Viscometer reading is differ-
ent from bench top viscome-
ter.
1. Damaged torsion element.
2. Solids in measuring chamber.
3. Incorrect wiring on Sensing end
cap.
1. Rheology of process fluid may
produce these results.
2. Temperature difference between
process fluid on-line and
fluid at bench top.
1. Refer to Sensing End
Cap Service in
Section 6.
2. Refer to Disassembly
and Cleaning in
Section 5.
3. Refer to Sensing End
Cap Service in
Section 6.
1. Refer to Correlation
with other Measure
ments in Section 1.
2. Ensure that both read-
ings are taken at the
same temperature or
refer to Correlation
with Other Measure
ments in Section 1.
