摘要： A device for detecting leakage of liquid in a tank, in which, even if the liquid in the tank is a low viscosity liquid, degradation in flow rate measurement accuracy by an indirectly heated flow rate meter can be suppressed, so that a very fine amount of leakage can be accurately detected for a long period without degradation in detection accuracy. The liquid in the tank that is led in and out from a liquid lead-in/lead-out section (12) is lead in and out from the lower end of a measurement fine tube (13b, 13b′, 13″) positioned in the flow rate measurement section (13). A measurement tube (17) of a liquid storage section (14) is connected to the upper end of the measurement fine tube. The measurement tube (17) has a larger cross-sectional area than the measurement fine tube. The device has a flow rate sensor section that is attached to the measurement fine tube and measures the flow rate of the liquid. The flow rate sensor section includes a heater (135) and temperature sensors (133, 134). The distance L1 in the measurement fine tube measured from a position corresponding to the heater (135) to an upper end opening of the measurement fine tube is not less than 20 mm and not more than 45 mm.

摘要： A fluid identification sensor that includes a fluid identification element and a fluid temperature detecting element that is disposed separately at a predefined distance from the fluid identification element is used. A voltage is applied to the fluid identification element for a prescribed time to heat a identification target fluid. A first output value that is an electrical output value corresponding to a first temperature of a fluid identification element and a second output value that is an electrical output value corresponding to a second temperature of a fluid identification element are obtained. A fluid identification is carried out by comparing a rate of change of the first output value and the second output value with a rate of change of a first output value and a second output value for a reference fluid, which has been measured in advance.
