Field Verication:
Cherne’s Aluminum Fin Style Deection
Gauges are designed to be eld veried
by inspectors without the use of a proving
ring. Simply place two ns end-to-end as
pictured below (1) and measure the width.
Add one inch to the mandrel (2) and you
have the outside dimension of the gauge.
Using this method simplies the inspector's
job of verifying sizes on deection gauges.
Aluminum Fin Style Deection
Gauge Features:
•
Lightweight, corrosion-resistant
•
Field-veriable without a proving ring
•
Assembles without tools
•
All sizes t through standard 24" manhole
•
Fins for 4"-15" gauges have skid size equal
to the nominal pipe size—gauge will meet
regional codes and will not tip in the line
•
Nine-n design ensures testing accuracy
•
Open design allows gravel and debris
pass-through
