Abstract

A Selective Catalytic Reduction sensor that does not degrade a measurement accuracy of a quality sensor even when a remaining amount of a urea tank is reduced. A quality sensor is installed between a minimum remaining amount liquid level and a bottom portion of the urea tank; a drop pipe is installed from a ceiling portion of the urea tank to a top space in the urea tank; a support is installed from a bottom portion to the ceiling portion of the urea tank; the quality sensor and the drop pipe are integrated through the support; and a bubble diffusion region caused by the urea aqueous solution dropping from the drop pipe is out of a sensitive region of the quality sensor.
