Welding Requirements; Meter Body Requirements When Flushing - Panametrics BWT System Installation Manual

1.6

Welding Requirements

Prior to welding, do the following:
• Remove power from the flowmeter console and disconnect the cables from the transducers.
• Make sure the inside diameter of the meter body and process pipe are properly aligned. Misalignment can
affect measurement accuracy.

Meter Body Requirements When Flushing

Panametrics strongly recommends using a dummy meter body during flushing operations; otherwise, damage may
occur for the following reasons:
• Fast moving solid objects in the flowing medium could damage the buffer faces.
• Flushing residue/sediment could clog nozzles.
In the event that a dummy meter body is not available for flushing operations, remove the buffers and plug the holes
properly for the temperature and pressure used. Blind flanges are typically used.
Reinstall the buffers and transducers after flushing using the information in this guide.
CAUTION!
BWT™ System Installation Guide
Be sure to use new gaskets when reinstalling buffers. Never reuse gaskets for safety
reasons and acoustic performance of the flowmeter.
