Full Pipe Recommendations

INSTALLATION

Not Ideal:

If pipe contains air bubbles or sediment 

(may affect accuracy)

Best

:

Improved accuracy results from

unimpeded electrodes

Electrode 

moved from 

top by rotating 

meter

Intermittent air

bubbles

miss electrode

Electrodes free 

from sediment 

build-up

Not Ideal:

Allows air pockets to form at meter

Recommended:

Keep pipe full at meter for accuracy

Not Ideal:

Post-valve cavitation can create air pocket

Recommended:

Keeps pipe full at meter for accuracy

Not Ideal:

Air can be trapped

Recommended:

Allows air to bleed off

Not Ideal:

Air can be trapped

Recommended:

Allows air to bleed off
