glass plate level gauge-ULB Series glass plate liquid level gauge
ULB-S double color glass plate liquid level Gauge can supersede ULB ordinary type glass plate liquid level Gauge. It adopts flanges connection and can be applied to measure liquid level in pressured or open container in various industrial fields. It is applicable for liquid level measurement for water, liquid ammonia, light oil, liquid gas, etc.
Structure principleULB-S series double color glass plate liquid level Gauge applies double color principle that when light goes through different mediums, it produce different reflection and reflection. Via using color filter, the light in different mediums presents different color. Through the glass plate, when there is liquid inside, the color is green, while there is gas, the color is red. So, the Gauge has two colors exhibition and the interface of the liquid and gas is very clear.
