Provided is a fluid state identification device including a fluid state identification unit having a sensor part and a support part, and a cover surrounding the fluid state identification unit. The support part has a front surface part and a rear surface part which are located opposite to each other. The sensor part is located on the front surface part side. The cover has a lower opening and an upper opening. Inside the cover, a first fluid flow route running through a front area adjacent to the support front surface part and a second fluid flow route running through a rear area adjacent to the support rear surface part are formed and located so as to make the fluidity of the fluid in the second fluid flow route higher than the fluidity of the fluid in the first fluid flow route.

Fluid state identification device

A reductant container having: a tank main body that accommodates a reductant; a heating member disposed in the tank main body and configured to generate heat so as to increase a temperature of the reductant; a covering member covering the heating member and having an inflow portion, the inflow portion allowing some of the reductant to flow into the covering member; a reductant supply pipe through which the reductant in the covering member is supplied to the outside of the tank main body; and a temperature measuring unit having a temperature sensor disposed in the covering member to sense a temperature of the reductant, the temperature measuring unit determining the temperature sensed by the temperature sensor, wherein the covering member has an upper wall covering the heating member from above, the upper wall having a lower surface that is inclined so as to be raised toward the temperature sensor.
