General piping guidelines
•
When measuring fluids containing suspended solids, install permanent valves at regular intervals to
blow-down piping.
•
Blow-down all lines on new installations with compressed air or steam and flush them with process
fluids (where possible) before connecting these lines to the transmitter's meter body.
•
Be sure all the valves in the blow-down lines are closed tight after the initial blow-down procedure
and each maintenance procedure after that.
