Accuracy you can rely on
Features Mobile Master Meter Prover
NMi tests conrm long life / low cost of
ownership
Master meter provers from KROHNE are supplied
as standard with 0.07% aqccuracy. They are
available as an option with 0.05% accuracy. This
increased accuracy demands higher manufacturing
specications and increased linearisation testing.
In recent total-mounted system tests some meter
runs have shown exceptional calibration results of an
average 0.03%. Although we cannot guarantee this
gure, it does show that we manufacture with a large
margin of metering reliability. The advantage is the
reality that even severe drifting in the eld, due to
adverse effects will rarely cause the system to drift
beyond the specied limits of accuracy, and therefore
the need for period re-calibration is reduced to an
absolute minimum. NMi stipulates re-calibration 2
years after rst in-eld use, and only every 4 years
thereafter for KROHNE Master Meter Provers
Our mobile provers are tested in the 500,000 litre
water tower in the KROHNE facilities, against a
piston prover and against rened oil at NMi. More
often than not, the customers own internal rules
demand re-calibration long before this is due for
technical reasons. We frequently test meters after
over 10 years service, only to nd that they are within
a fraction of a percent of their initial calibration. This
is an inherent advantage in choosing a KROHNE
ultrasonic meter.
