FIELD: engines and pumps.
SUBSTANCE: proposed control device incorporates control mechanism to control input power fed into pump. Designed output power is compared for a time with input power by control device data processor. Proposed device may be used to define the state of pump true output power. This offers actual advantages in operating multiple pumps whereat direct measurement of pump output power is hardly possible.
EFFECT: higher accuracy.
