No-blind zone double-color water gauge

The invention discloses a no-blind zone double-color water gauge. The no-blind zone double-color water gauge comprises a light source front cover and a light source rear cover. Two perspective holes are formed on one side face of the light source front cover. A gauge body is arranged in the light source front cover. The upper portion of the gauge body is connected with a steam side flange. The lower portion of the gauge body is connected with a water side flange. Transparent holes are formed in the gauge body. Two rows of gauge body window sets are formed in one side face of the gauge body. Each row of gauge body window set corresponds to the corresponding perspective hole and includes a plurality of gauge body windows formed at intervals. The gauge body windows of the two rows of gauge body window sets are arranged in a crossed mode and connected end to end. Each gauge body window comprises a plane located in the middle and inclined faces arranged on the two sides of the plane. The inclined faces incline by 9 degrees relative to the side faces, close to the perspective holes, of the gauge body. Light sources corresponding to the transparent holes are arranged in the light source rear cover. A dimming rotary knob is arranged on the top of the light source rear cover. The problem that in the prior art, water level blind zones exist can be solved, water level blind zones are avoided, and the detection result is accurate and reliable.
