Abstract
The present disclosure discloses a device, a container and a method for measuring a liquid volume in a container based on air pressure sensing. The measuring device includes a moving member, a unidirectional member, an air pressure detection device and a controller. The moving member is connected with a con tamer to be detected to form a gas storage space. By using the unidirectional member, the gas storage space is communicated with the external environment when the volume decreases, and remains sealed with the external environment when the volume increases. The air pressure detection device is disposed on the moving member to measure a pressure value in the gas storage space. The device accurately measures the liquid volume in the container, effectively eliminates the interference of liquid motion on the measurement result, and can be conveniently used to detect a water volume in the natural usage.
