Tank system including multiple tanks and control method thereof

A flow rate control method of a tank system having multiple tanks, said tank system making a joint flow of a fluid released from the multiple tanks and supplying the joint flow to a downstream device, which is located downstream of the multiple tanks, said flow rate control method comprising the steps of:

• individually measuring internal pressures of the multiple tanks as primary pressures;
• pressure;
• individually controlling, for the joint flow with a supply flow rate of the fluid to be released, the release flow rate by each of the multiple tanks;
• and
• individually regulating release flow rates of the fluid to be released from the multiple tanks by monitoring current primary pressures that are continuously provided from the primary pressure measurement modules to the pressure control module.

A tank system that has multiple tanks containing a fluid and that supplies a flow of the fluid released from the multiple tanks to a device located downstream of the multiple tanks, the tank system comprising;

• primary pressure sensors that individually measure internal pressures of the multiple tanks as primary pressures;
• valves that are disposed between the multiple tanks and the device;
• and
• a controller that specifies the tank having the lowest primary pressure based on the measured primary pressure of the multiple tanks and that regulates the flow of the fluid to be released from the valve that corresponds to the specified lowest primary pressure tank, and allows the flow of fluid to be released from the valve that corresponds to the tank having a higher primary pressure than that of the lowest primary pressure tank, so as to control the supply flow rate to the device.

A tank system that has multiple tanks containing a fluid and that supplies a flow of the fluid released from the multiple tanks to a device located downstream of the multiple tanks, the tank system comprising;

• primary sensing means for individually measuring internal pressures of the multiple tanks as primary pressures;
• flow regulating means disposed between the multiple tanks and the device;
• and
• control means for specifying the tank having the lowest primary pressure based on the measured primary pressure of the multiple tanks and for regulating the flow of the fluid to be released from the flow regulating means that corresponds to the tank having the lowest primary pressure among the multiple tanks, and for allowing the flow of fluid to be released from the flow regulating means that corresponds to the tank having a higher primary pressure than that of the lowest primary pressure tank, so as to control the supply flow rate to the device.
