PURPOSE: An electric water gauge for preventing hydraulic jump and freezing destruction is provided to prevent hydraulic jump and to safely protect a digital measuring device. CONSTITUTION: An electric water gauge for preventing hydraulic jump comprises an outer shield body(10), a flow meter(20), a digital measuring device(30), a joining cover(40), and a supporting member. A guide groove portion(51) for guiding the bottom part of the digital measuring device is formed in the upper part of the supporting member. An upper recessed groove(52) is formed in the central part of the guiding groove portion and a guiding projection(53) is formed into a form which is not drawn outside of the upper recessed groove inside the upper recessed groove. An assembly projection(54) is formed in the bottom part of the opposite side in which the upper recessed groove is formed and a lower recessed groove(55) is formed in the central part of the assembly projection. The supporting member is seated in a guiding hole of the outer shield body and a shielding ring(60) for preventing magnetic field signal disturbance is installed inside the upper recessed groove of the supporting member. A freezing destruction preventing groove(70) is assembled in the assembly projection in the supporting member. |
