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 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 Nitrile Rubber gasket(included).

Adjustable liquid-level gauges are designed for top mounting only. These gauges are equipped with 20.5" [520mm] long float arms which can be cut to fit tank dimensions. Request data sheet DS-337 for proper cut lengths and instructions on how to install the float and crimp it in place.
