RFRG

A glass rotameter uses an upward-widening vertical tapered glass tube and an internal float as core measuring parts. Upward fluid flow creates differential pressure to raise the float. Equilibrium is achieved when upward pressure force, buoyancy and viscous lift counteract the float gravity. Flow rate is proportional to float height and flow passage area; float position indicates the measured flow value.

Economical

Suitable for flow measurement across chemical, petroleum, light industry, pharmaceutical, fertilizer, chemical fiber, food, dye, papermaking, national defense and research fields.
