Water level measuring apparatus capable of improving measuring accuracy

The invention discloses a water level measuring apparatus capable of improving the measuring accuracy, relates to the field of measurement of underground water lines, and aims to solve the problem ofinaccurate measurement of the underground water lines due to interference of wet well walls by the conventional underground water level measuring apparatus. According to the technical scheme, the apparatus is characterized in that an original probe is replaced by a storage block, the storage block is provided with a first storage chamber and a second storage chamber in sequence along the directionfar from the growth of a transmission line, a separating plate for separating the first storage chamber and the second storage chamber is arranged between the first storage chamber and the second storage chamber, a contact connected with the transmission line is arranged in the first storage chamber, the separating plate is provided with a telescoping rod in a sliding manner, one end, located inthe first storage chamber,
