The Japanese Patent Publication discloses a device for detecting the type of oil in each chamber in a tank truck that can carry a plurality of types of oil. According to the detection device, a transparent body such as a prism is placed inside the tank, and light is passed through the transparent body, and the transmittance, refractive index, and reflection on the surface of the transparent body are determined depending on the type of oil. By focusing on the fact that the amount of detected light ultimately extracted from the output side of the transparent body changes as the ratio changes, the type of oil is detected by comparing it with a reference value. In addition, Japanese Patent Application Publication No. 1986-
In the oil type detection method disclosed in Publication No. 259934, a zero balance circuit is provided, and zero correction is performed based on the amount of light passing when no oil is present.

いる。 Furthermore, although a lamp such as a halogen lamp is used as a light source, the battery voltage of the tank truck that serves as the lamp's power source tends to fluctuate, and oil is present during measurement to determine oil type and for zero correction. Since the time is different from when measuring the amount of light passing when the sensor is not in use, the detection method disclosed in Japanese Patent Application Laid-open No. 60-259934 performs zero correction, but is prone to errors due to battery voltage fluctuations. Also, when introducing oil from the tank chamber into the unloading pipe, the oil becomes cloudy in the unloading pipe, and it takes time for the cloud to disappear. Variations in the amount of light passing due to the degree of cloudiness increase. JP-A-60-259934 and JP-A-60-
In the oil type detection method such as that disclosed in Publication No. 252244, the amount of light passing through the oil is greatly affected by cloudiness, resulting in a decrease in detection accuracy.

比較する。Vi，Vjの検出時のバツテリ電圧が、

＋５％変動したとする。 In the tank truck 10, voltage fluctuations in the battery that serves as a power source for the light source 34 are likely to occur. The accuracy of the oil type detection method using formula (a) will be compared with the method of detecting oil type from Vi/Vio (hereinafter referred to as "formula (b)"). The battery voltage when detecting Vi and Vj is
Assume that the battery voltage fluctuates by +5% when detecting Vio and Vjo.
(a)式では：
（Vi＊1.05／Vio）／（Vj＊1.05／Vjo）＝(a)式
(b)式では：
（Vi＊1.05／Vio）＝(b)式＊0.05
すなわち、(a)式では、変動の影響が零であるの

％とする。 In addition, in order to detect the oil type, the bottom valves 18a, 1
When 8b or 18c is opened and oil is introduced into the discharge passage 20, cloudiness occurs in the discharge passage 20. This cloudiness affects the amount of light passing through the discharge passage 20 and takes a long time to disappear, so waiting until the cloudiness disappears before detecting the oil type causes a delay in detection. Equation (a) and when cloudiness still exists
Consider the effect on the value of equation (b). The visible light from the light source 34 has a wavelength of 0.4 to 0.7 μm, whereas the diameter of the white cloud bubble is much larger, so the white cloud provides equal scattering for light of all wavelengths or wavelength bands. In addition, the decrease in the amount of light passing due to cloudiness is 20
%.
(a)式では：
（Vi＊0.8／Vio）／（Vj＊0.8／Vjo）＝(a)式
(b)式では：
（Vi＊0.8／Vio）＝(b)式＊0.8
すなわち、(a)式では、変動の影響が零であるの
に対し、(b)式では、変動の影響が20％である。 In formula (a): (Vi*0.8/Vio)/(Vj*0.8/Vjo) = (a) formula (b): (Vi*0.8/Vio) = (b) formula*0.8 That is, (a In equation (b), the effect of variation is zero, whereas in equation (b), the effect of variation is 20%.
