Abstract

PURPOSE: To carry out accurate control even while a signal transmitter is in trouble by performing the control according to the measurement value of measurement terminal pressure in a telemeter normal state and by controlling exhaustion pressure on the basis of the memory value of a memory method in a telemeter fault state.
CONSTITUTION: While measurement-terminal-pressure control is in process with the telemeter in a normal state, a pipe loss at time (ti) is calculated and stored. When terminal water level (h2) can not be monitored in the pump house due to the fault of the telemeter, terminal water level (h2) is estimated by using characteristic hL(Q) of pipe loss to flow Q calculated and stored and then compared with a terminal-pressure set value, thereby controlling the pump rate.
