When the bottle containing the liq. is in a vertical position the dosimeter is fixed at the stopper position. When the liquid is tipped the ball remains locked thanks to a chamfer placed at the base of the dosimeter body. During this time liquid passes through an orifice. After a progressive inclination of the bottle the ball is unlocked and descends into the dosimeter body. When the ball reaches the orifice it prevents the liquid from leaving the bottle. The time of descent of the ball determines the dose or quantity of liquid run off. - The descent time is a function of the diameter of a calibrated orifice found on the moving part. At the end of the operation the valve is opened allowing liquid to return rapidly into the bottle. The device differs from previous models in that the dose is determined in a moving pivoting or sliding part. These moving parts may be removeably or not. The advantage of the device is that it is possible to change the dose without changing the dosimeter, only the calibrated moving part.(0/1)
