Title: Measuring method for flow rate of electrolytic solution
Inventor: NAKANO OSAMU
IPC: G01F1/00
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which the circulation amount of an electrolytic solution can be measured with good accuracy and simply by a method wherein, while a constant-current electrolytic operation is being performed, the flow rate of the electrolytic solution is found on the basis of the relationship between the flow rate of the electrolytic solution and a voltage which is applied across electrodes. SOLUTION: A constant-current power supply 2 for electrolysis is connected across an anode 4 and a cathode 5, and its potential change is measured by a recorder 3. An electrolytic solution is poured in advance up to a definite water level in such a way that both electrodes 4, 5 are immersed. After that, while a constant-current electrolytic operation is being performed, the electrolytic solution is pulled out a constant amount at a time from a discharge port 6 (a supply port 7 is closed). At this time, the drop speed of a water level is obtained by a level gage 8, and a potential change across both electrodes of the power supply 2 is obtained simultaneously from the recorder 3. In addition, inversely, an electrolytic solution is supplied a constant amount at a time from the supply port 7 from a state that a water level is low (the discharge port 6 is closed). The drop speed of the water level is obtained by the level gage 8, and a potential across both electrodes is obtained simultaneously by the recorder 3. When the relationship between the water level and the potential change is found in this manner, the supply speed and the liquid discharge speed of the electrolytic solution can be found on the basis of the potential change.
