Application
The M6300 series Magnetel® Rough Rider® gauges are designed to withstand the vibration and shock inherent in mobile service. Their service life in both on-highway and off-road transports, carrying liquids like crude oil, is unsurpassed. Models 6339M11 and 6342M11 are intended for on-highway service applications. Models 6339M12 and 6342M12 are intended for both on-highway and off-road, including crude oil and/or water service applications.  The Magnetel® Rough Rider® gauges are designed for working pressures ranging from atmospheric to 450 [31 Bar] psig.

General Information & Features
The Magnetel® Rough Rider® gauges are to be installed in the side or end of mobile tanks at the centerline. They are equipped with an exclusive spring-controlled shock absorber on the float arm which substantially reduces the stress that quickly destroys conventional gauges. Angle mounting gauges are also available. 6339M12 models include as standard a heavy-duty support tube, making them suitable for hauling crude oil, either on or off highway.

The 6339M12 models are made of 300 series stainless steel, with the Alnico magnet fully enclosed in a stainless-steel housing. (Including Counterbalance).

The 6339M11 models incorporate a plated steel counterbalance and an Alnico magnet with all other wetted parts made of 300 series stainless-steel. (Except Counterbalance)

These gauges allow a continuous reading between 5% and 95% of tank contents. The 6339M incorporates a 4″ [100 mm] dial and the 6342M incorporates an 8″ [200 mm] dial. When necessary, the dials are easily replaceable.
