FIELD: hygrometry, water supply engineering. SUBSTANCE: intake tube is connected with water intake well which has spire-like made walls so water flow is feeding by two ways: from conical-type bottom holes and from wall spire-like tray. Walls of vertical part of intake tube has colored scale marks and indicating ball-float inside tube which moves along guiding rope. Water rotation feeding prevent drift setting in gauge tube owing to well walls construction. EFFECT: more long life time of water gauge station operating. 2 tb, 1 dwg
