FM Instruments Acrylic Body Rotameters are precision flow measuring instruments designed for accurate indication and control of liquid and gas flow in industrial applications. These rotameters operate on the variable area flow measurement principle, where the float moves vertically inside a tapered acrylic tube according to the flow rate.

The transparent acrylic body provides clear visibility of the float and flow scale. Available with or without isolation valves, and in multiple connection types including threaded, union, tri-clover, and flanged connections.
