We are offering Acrylic Rotameter which is mainly used in the indoor applications. This is a type of Variable Area Flow Meter, which is useful for air, water and other non-corrosive fluids. It has a tapered tube that is generally made from acrylic block. It also has a float which is made of PTFE or stainless steel (grade 316 / 304). The basic material of construction for these equipment is acrylic and the tube resides within the acrylic block. Acrylic Rotameter has a constant differential pressure throughout the annulus area. Float's vertical position on scale corresponds to the instantaneous flow rate.
