Glass Tube Variable Area Flow Meter
The Glass Tube Variable Area flow meter GTG20 for liquids and gases feature a tapered glass tube and operate on the float measuring principle. They have a common basic design and various standard connections. The flow-meters are installed in a vertical pipe run with flow from bottom to top.
Glass Measuring Cones
The measuring cones are made of high temperature-resistant stress-free borosilicate glass. Cones and floats are individually replaceable (accuracy class 1.6).
The measuring cones are operated with A III floats. These floats feature three notches on the top guiding edge which cause the floats to rotate and maintain a stable position during flow.
