Background technique

Pore and water is one of the laboratory experiments of groundwater hydrology, the main purpose is to deepen the understanding of the concepts of porosity, water supply and water holding capacity of loose rock. The feed water meter is the main experimental instrument for measuring porosity, feed water and water holding capacity. At present, the laboratory mainly uses a rubber-tipped burette to replenish and dewater the samples in the feed water meter, and read it manually according to the scale in the burette. Take the corresponding amount of water replenishment and water withdrawal to calculate the porosity and water supply. However, the volume of the rubber burette is small, and it needs to replenish water many times during the experiment. Multiple manual readings will lead to the accumulation of experimental errors, and the sample When replenishing water, it is also artificially judged whether the sample is saturated, so it is easy to cause excessive or insufficient replenishment of water, resulting in experimental errors.
