Installation in measurement chambers subject to
(constant) flooding is possible with the IP68 rated
version. The chambers can even be completely
surpassed if the IP68 version is combined with our
special subsoil coating, allowing the OPTIFLUX 2000
to be installed directly in the ground.

In combination with the IFC 300 converter the
OPTIFLUX 2000 is suitable for custody transfer
applications. It meets the requirements of OIML R49
and can be verified according to Annex MI-001 of the
Measuring Instruments Directive (MID)
All water meters for legal metrology purposes in
Europe require certification under the MID. The EC
type examination certificate for the is valid for the
compact and the remote version and applies for
forward and reverse flow.

PRODUCT FEATURES
1.3 Measuring principle
An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic
field. This magnetic field is generated by a current, flowing through a pair of field coils.
Inside of the fluid, a voltage U is generated:
U = v * k * B * D
U = v * k * B * D
U = v * k * B * DU = v * k * B * D
in which:
v = mean flow velocity
k = factor correcting for geometry
B = magnetic field strength
D = inner diameter of flowmeter
The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v
and thus the flow rate Q. A signal converter is used to amplify the signal voltage, filter it and
convert it into signals for totalizing, recording and output processing.
