Coriolis Meter
The Coriolis Meter is a very precise mass flow meter that can be used to measure volume for
fluids of consistent density. It is extremely durable and has no sensitive components directly
exposed to fluids.
The stainless steel mass flow meter is used for DEF only. It contains no mechanical moving
parts and is extremely accurate (M10006A003).
Some important considerations for servicing the Coriolis Meter include the following:
• The meter electronic parts are serviceable by replacement. Typical error codes associated
with pulsers indicate symptoms of failure in the electronic parts. In case of such
symptoms, replace the electronic parts.
• The expensive meter electronics and hydraulics assembly can also be replaced.
• The meter hydraulics including the transducers are not serviceable. Replace the meter, if
these components are damaged.
• When servicing the electronics, you must reuse the purple chip from the previous meter or
the meter will not be properly adjusted. Use ESD protection when servicing the
electronics.
