摘要： PROBLEM TO BE SOLVED: To determine whether a measuring liquid is a specific kind of liquid that is more accurate than the conventional art.
SOLUTION: The outer surface (temperature rise region) of a ceramic insulating substrate of a part, having a heater section 44 of a state detection element 32, is brought into contact with the measuring object liquid, so that it is not necessary to perform indirect heat transfer to the measuring object liquid via a fin in a manner different from the conventional art, and the determination of the measuring object liquid can be attained in a shorter time than in the conventional art. A protector 36 that surrounds the periphery of a temperature rise region of the state detection element 32 is disposed, and by restricting the flow of the measuring object liquid around the temperature rise region, the heat of a heat resistor is hard to be taken by the liquid flow. Thus, the temperature rise region 46 of the state detection element 32 is brought into contact with the measuring object liquid to shorten the time required for determining the measuring object liquid, and the variations in the resistance value according to the temperature by the heat resistor are apt to appear, and the determination of the measuring object liquid, or the like, can be performed accurately.

摘要： PROBLEM TO BE SOLVED: To provide a liquid state detection device capable of determining a stationary state based on a detection result of the level of liquid stored in a liquid storage container, and determining a concentration abnormality more accurately. SOLUTION: A differential value ΔVmn between each voltage value of a heating resister measured after start of energization and after elapse of a fixed time or its concentration conversion value Cn is compared with a threshold, and thereby an abnormal state of urea aqueous solution is detected (S51, S52, S71). If the solution is in the abnormal state, stationary state determination based on a detection result of the level is performed (S61, 72, 81), and if the solution is not in the stationary state, an addition value of a counter is decreased compared with the case in the stationary state. Hereby, even if an abnormal state is detected temporarily by an influence of swing of the urea aqueous solution or the like, reporting (S66, 77, 86) is not performed immediately, but a detection opportunity of the abnormal state performed until being determined to be in the abnormal state is increased, to thereby heighten reliability of determination of the abnormal state.
