Abstract

PURPOSE:To obtain a liquid weighing device which is not influenced by the opening and closing precision of a water discharge valve and a water feed valve, by a method wherein a weighing tube, provided with water level detectors at an upper and a lower end parts, is connected in parallel to a weighing tank having a water feed valve and a water discharge valve at an upper and a lower end thereof. CONSTITUTION:Water in a tank 6 is fed into a weighing tank 1 through a water feed valve 2, and water in the weighing tank 1 is discharged through a water discharge valve 3. The weighing tank 1 is coupled in parallel to a weighing pipe 4 provided with water level detectors at an upper and a lower end. The water feed valve 2 is opened in a condition to close the water discharge valve 3, which is of an electromagnetic valve, and water in the tank 1 is transferred to the weighing tank 1. When the water level detector 5 at the upper end of the weighing pipe 4 detects water, the water feed valve 2 is closed, and the water discharge valve 3 is opened. When the water level detector 5 at the lower end detects the water level, the water discharge valve 3 is closed, and the water feed valve 2 is opened. This permits weighing of a constant amount of liquid irrespective of the opening and closing precision of the water feed valve and water discharge valve.
