摘要
The invention relates to a probe for determining the level of the liquid phase of liquefied petroleum gases (LPG) and other liquefied gases stored in pressurised cylinders. The cylinder contains a buoy that floats on the liquid phase and a magnet joined to the buoy , said magnet maintaining the necessary orientation and distance to the cylinder wall either by means of a guide housed inside the cylinder or a rocking mechanism that associates the movement of the buoy at one of its ends with a movement of the magnet at the other end , in both cases allowing the intensity of the magnetic field produced by the magnet to be measured from the exterior using a smartphone with a Hall sensor , the latter being used to associate the position of the magnet with the height of the liquid phase by means of a scale provided on the exterior of the cylinder or directly using the measurement obtained. A different embodiment comprises the use of a hollow flexible rod filled with viscoelastic material and a pressure transducer.
