When using a standpipe, fixed to the top of a vessel, ensure that the open
end of the standpipe is clear of any obstructions such as weld seams,
gaskets etc. to avoid unwanted signal returns.
If using standpipes which extend into the vessel, beyond the blanking
distance, but not as far as the empty level, then the open end of the
standpipe should be cut to an angle of 45
o .
When using the dBi Series Intelligent Transducer
to measure ‘aggressive,
materials such as ‘alkaline’ and ‘acids’ it is recommended that either a PVDF
or an optional PTFE faced Flanged Transducer is used. Please consult Pulsar
for full availability of options.
Cable
The dBi Series Intelligent Transducer comes with a fitted integral cable, if this
cable is extended then the total capacitance must not exceed the limits for
the voltage applied.
Correct
standpipe
installation
Pipe should be free
of obstructions
such as weld
seams.
The maximum level
(100% of Span) is
inside the Blanking
Distance.
Important Notice
In the case of the Ex mb version the cable is fitted with an over current
protection device in the form of a fuse, please note that
under no
circumstances should this fuse be removed . The fuse must be fitted in
