The invention discloses a non-contact container liquid level measuring device and method. The non-contact container liquid level measuring device comprises an upper computer and at least one liquid level measuring device. Each liquid level measuring device is mainly composed of a capacitive liquid level sensor assembly, a data processing module, a communication module and an upper computer. The upper surface of the capacitive liquid level sensor is tightly attached to the outer wall of the container to be detected, the output end of the capacitive liquid level sensor is connected with the input end of the weak capacitance detection module, the output end of the weak capacitance detection module is connected with the input end of the data processing module, the data processing module is connected with the communication module, and the communication module is connected with the upper computer. According to the invention, the change value of the liquid level and the volume of the liquid in the container can be c
