摘要

A housing of a water gauge and a painting method for the same are provided to prevent the pollution of the water passing through the inside of the housing by peel-off or cracks of paints applied on the inside of the housing. A method for painting a housing of a water gauge comprises the steps of: grinding the surface of the housing by spraying(S10); firstly heating the housing(S20); spraying paints containing one selected from a group comprising polyester, silicone, and epoxy types, on the surface of the housing(S30); collecting some of the sprayed paints by using a dust collector(S40); secondly heating the housing coated with the paints(S50); and cooling down the housing in the natural state(S60). Spraying of the paints is executed by a sand blaster method.
