Claims

[Scope of utility model registration request]

Flowmeters and control valves are installed on the inflow and outflow sides of the reservoir, respectively.
In a system in which inflow water and outflow water to a water distribution reservoir are controlled through this control valve, a pressure gauge is provided on the outflow side of the water distribution reservoir, and a water level gauge is provided in the water distribution reservoir, and the water level is a first function generating means for inputting a water/level signal detected by the pressure gauge and outputting a pressure signal corresponding to the water level signal on both sides of a predetermined water level band; and a pressure detection signal from the pressure gauge. Determine the deviation from the set pressure signal, add the output signal of the first function generating means to this deviation value as a correction signal,
a first calculation unit that outputs an operation signal for the outflow side control valve; and a second calculation unit that receives the water level signal from the water level meter and outputs a flow rate signal corresponding to the water level signal when the water level exceeds a predetermined water level level. Find the deviation between the function generating means, a predetermined set receiving water flow rate signal, and the flow rate signal from the flow meter on the inflow side, and subtract the output signal from the second function generating means as a correction signal from this deviation value. 1. A water distribution amount control device comprising: a second calculation section that outputs an operation signal for an inflow-side control valve;
