Liquid meter has tank for liquid, vessel of constant level, inlet branch pipe, receiving vessel for dozed liquid, this is divided into collection and discharge chambers, dosing cup placed under the discharge branch pipe and over collection chamber connected like the constant level vessel and discharge chamber with discharge mains to tank for liquid. In collection chamber with possibility of change of its position bailer is installed for trapping liquid dozed with the cup. The cup is installed on axle with possibility of rotation and has side surfaces parallel to axis of rotation of the cup and normal (opposite) to the last one. One of two parallel side surfaces of the cup is tilted at angle to vertical plane that goes through the axis of rotation of the cup and is lower than all the other side surfaces of the cup, at that the other surface is opposite to the inclined one and has in the lower part a counterweight. One of normal (opposite) has a screen for liquid trapping, this is placed in its upper part, at the side of counterweight. |
