2.2.2 High Viscosity piping requirements
The piping requirements for High Viscosity meter applications are shown in Figure 2-5.

Sunshields, to be provided by the customer, may be required to prevent exceeding the ambient
operating temperature range when the meter is mounted in a location with extremely hot
climates.
HIGH VISCOSITY FLOW MEASUREMENT METER RECALIBRATION
In high viscosity meter applications, if the connection between the upstream meter flange
(Figure 2-5, Item D) and the Venturi reducer (Figure 2-5, Item C) is disassembled or disturbed for any
reason, the meter will need to be recalibrated in accordance with Daniel recommendations. 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.

SUNSHIELD PROTECTION
Install a sunshield to prevent prolonged exposure to direct sunlight in extreme climates.
Failure to shield the meter may result in exceeding the process temperature range and damage transmitter
electronics.
