Emerson Rosemount 3814 - 1.7 Meter specifications

CAUTION
HIGH VISCOSITY FLOW MEASUREMENT METER RECALIBRATION
In high viscosity meter applications, if the connection between the upstream
meter flange (Figure 1-5, Item D) and the Venturi reducer (Figure 1-5, Item C) is
disassembled or disturbed for any reason, the meter will need to be recalibrated
in accordance with Rosemount recommendations. Alignment of this flange joint is
critical in the performance of the meter. It is recommended to consult Emerson
Customer 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.
