Diesel exhaust fluid system

An exhaust gas purification system comprising:

• a tank for storing a fluid;
• a mounting plate coupled to the tank;
• a baffle positioned inside the tank below the mounting plate, the baffle having an outer wall defining an interior cavity and an opening;
• a sensor positioned in the interior cavity for detecting a condition of the fluid;
• a supply conduit extending through the mounting plate into the tank;
• and
• a return conduit extending through the mounting plate into the tank and having an outlet positioned to discharge the fluid below the opening and exterior to the baffle.

An exhaust gas purification system comprising:

• an injector for introducing a fluid into an exhaust stream;
• a supply device to supply the fluid to the injector;
• a tank for storing the fluid;
• a baffle positioned inside the tank, the baffle having an outer wall defining an interior cavity and an opening;
• a sensor positioned in the interior cavity for detecting a condition of the fluid;
• a supply conduit extending into the tank to supply the fluid from the tank to the supply device;
• and
• a return conduit extending into the tank to return the fluid from the supply device to the tank, the return conduit extending through the opening and through the outer wall of the baffle and having an outlet positioned to discharge the fluid outside of the baffle.
