Abstract

PURPOSE: To enable the measurement of delivery corresponding with r.p.m. by previously storing the lift-delivery characteristic corresponding with r.p.m. into a function generating section.
CONSTITUTION: Total lift P1 is obtained by subtracting the suction pressure signal of a suction pressure gauge 15 from the delivery pressure of a delivery pressure gauge 16, then the total lift P2 corresponding to the max. r.p.m. is obtained from said total lift P1 and the r.p.m. n1 thereafter prestored total lift-delivery characteristic at 100% r.p.m. is used to perform the reverse conversion on the basis of said total lift P2 thus to obtain the delivery q2 and another delivery q1 at the r.p.m. n1. The present delivery of pump is measured during when each sampling pulse is produced through such step thus to control the delivery automatically.
