Clamp-on Transducer Problems (cont.)
4. PHYSICAL DAMAGE
Transducers may be physically damaged by dropping them onto a
hard surface or striking them against another object. Usually the
connector on the transducer is the part that is damaged, as it is the
most fragile. Minor damage may be repaired by carefully bending
the connector back into shape. If the connector cannot be
repaired, replace the transducers. Note that transducers must be
replaced in pairs, and that after replacement the flowmeter
parameters should be checked (see Chapter 3, Programming Site
Data).
5. CYCLE SKIP CONDITION
A cycle skip is usually caused by a distorted or altered signal due
to poor couplant, bad wall, or unusual fluid disturbances. To
resolve a cycle skip, recouple both transducers with proper
couplant. Try standard CPL-1 couplant that is good to 212°F or
CPL-2 for up to 500 °F. In addition, make sure the pipe wall is
free of paint and rust.
Contact GE Panametrics if you cannot solve a transducer-related
problem.
