BAMO RA77/FA77’s design, plastic body and glass tube, makes them particularly suitable for aggressive fluids and corrosive environment. The measuring principle is that of the variable area flowmeter, the float is moved by the fluid inside a calibrated conical glass tube. The borosilicate glass conical tube is inside a plastic protection case with a transparent reading window.
