Kind Code:
A1
Abstract:
Provided is a weighing mechanism which can achieve highly accurate weighing of a solution even when the capacity of a weighing container is increased. Specifically, this weighing mechanism selectively obtains and weighs a plurality of types of solutions. The weighing mechanism is provided with: a sealed container; an inlet tube which passes through an upper wall of the sealed container and though which the solutions passes; a weighing container that is provided inside the sealed container while not being in contact with the inlet tube and receives the solutions flowing out from the inlet tube; a weighing sensor that measures the weight in the weighing container; a valve-attached outlet tube which is connected to a lower portion of the weighing container and is for guiding downward the solution inside the weighing container; and a discharge tube which is provided below the sealed container, receives the solution flowing out from the outlet tube, and causes the solution to flow out to a further downstream side. The outlet tube and the discharge tube are configured so as to be arranged along a common vertical line while not being in contact with each other.
