IPC: B01F5/00
Filed: 1993-02-15
Abstract: PURPOSE:To improve the precision of quality control and to easily change the mixing ratios by strictly monitoring the flow rate, etc., in a continuous liquid mixing device. CONSTITUTION:The values measured by load cells 11a, 11b which are weighing equipment for feed liquid tanks 10a, 10b are compared with the integrated values measured by mass flowmeter Ba, Bb.
