HIGH VISCOSITY FLOW MEASUREMENT METER RECALIBRATION
In high viscosity meter applications, if the connection between the upstream meter flange
(
,
Item D
) and the Venturi reducer (
Item C
) is disassembled or disturbed for
any reason, the meter will need to be recalibrated in accordance with Daniel recommenda-
tions. Alignment of this flange joint is critical in the performance of the meter. It is
recommended to consult Daniel Support for assistance when re-aligning this joint.
Failure to recalibrate the meter and correctly reinstall the flanged joint will result in faulty flow measurement.
