Claim:
A filler including conveying means for intermittently conveying vessels placed on a conveying rail by engaging the vessels, filling means disposed on a path of conveying the vessels for filling a liquid into the vessel, mensuration means for determining a quantity filled by the filling means, and control means for controlling an opening/closing of a liquid valve in the filling means, whereby a given quantity of liquid is filled into the vessel while the filled quantity is determined by the mensuration means; further comprising elevating means for elevating the conveying rail; moving means for moving the conveying means to a position where it engages a vessel and another position where it does not engage a vessel; a metering receptacle disposed in a manner corresponding to the position of the filling means to place a vessel thereon when the conveying rail is lowered and positioned at an elevation where it does not contact a vessel when the conveying rail is raised; and weight detecting means connected to the metering receptacle; the conveying rail being raised to support a vessel when a normal filling operation takes place, and the conveying rail being lowered to place a vessel on the metering receptacle when a sampling operation takes place, the mensuration means being effective to detect the weight of the liquid filled into the vessel by the weight detecting means.
