6700 SERIES GAUGE
5 BOLT GAUGE FOR GASOLINE OR DIESEL FUEL TANKS
Application
Measures gasoline or diesel fuel levels in tanks on trucks, boats, generators, recreational vehicles, and other applications.
General Information & Features
These top mounting magnetic liquid-level gauges are built to the high standards of all Rochester designed instruments. The construction permits the replacement of dials when necessary without releasing fumes or liquid to the atmosphere.
Both available types of dials are fractional and silicone-dampened, and are easily replaced by removing and reinstalling two screws. Rochester’s rugged gear drive incorporates shrouded, stainless-steel, beveled gears designed to work out any loose particles that might affect gear function. Sealing between the gauge and the tank is achieved through the use of the 0015-00423 Buna-N gasket.
