双色平板玻璃液位计Double-color Flat Glass Level Gauge

双色平板玻璃液位计采用坚硬的三棱硼硅玻璃板显示液位，无液体通过时显示红色，有液体通过时显示液体本色。该液位表的自闭阀性能良好，当需要时，可直接拆开清洗液位表的内腔而无需放尽水柜或油柜中的液体。其优越的性能是各种水柜和油柜液位显示的选择。

Double-color Flat Glass Level Gauge

Double-color flat glass level gauge adopts rigid triple borosilicate glass to show level. If no liquid passes through, it will indicate red; otherwise it will indicate the color of the liquid. The self-closing valve of the level gauge has excellent self-closing performance. When necessary, the level gauge’s intracavity can be cleaned by disassembling the gauge without draining of the liquid in water & oil tank. This excellent performance makes it the best choice for level indication of varied kinds of water & oil tank.
