Abstract

PURPOSE: To enable to conform to the change on the process, by means of setting up two set water levels for starting and stopping of the operation number controller of pumps respectively.
CONSTITUTION: The operation number controller of pumps 7 are allowed to be started, and the water level signal is inputted by means of detecting it from a water distributing pool 2 by a water level meter 4. At this time, the signals of flowmeters 5, 6 and the flow quantity of distributing water are read at the same time. Here, the detected value Ln of the water level metar 4 and the max. water level set value HH are compared, and when HH<Ln, the stop command against the pump groups 3 during they are in operation, is emerged, and when HH>Ln, it proceeds to the next step. When the min. water level is indicated as LL, and if LL>Ln, the starting command is emerged to the pump groups. The difference |Fs-Fh| of a signal Fs of the flowmeter 5 and a signal Fh of the flowmeter 6 is compared with a set value (r), and a prescribed operational command is given to the pumps 3 according as this.
