Claims

[Scope of utility model registration request]

A nozzle having a rectangular outlet for dropping liquid, and a lower part of the outlet of the nozzle for selectively diverting the liquid falling from the nozzle to either a weighing channel or a discharge channel. It is equipped with a commutation plate that is swingably arranged on the
In order to prevent the flow diverted by the diverter plate from overflowing to the opposite side over the upper edge of the rotary flow plate, a partition block is provided inside the outlet of the nozzle to divide the liquid and allow it to fall. A flow meter calibration device, characterized in that:
