General piping

 

 

• When measuring fluids containing suspended solids, install permanent

guidelines

 

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.
