FIELD: engines and pumps.
SUBSTANCE: fluid flow is throttled at pump outlet to preset magnitude. Throttling amount is controlled with the help of flow rate meter. Fluid temperature is measured at pump outlet. Temperature variation at pump outlet for preset time interval and pump differential pressure are used as diagnostics parameters.
EFFECT: simplified diagnostics hardware owing to rejection of fluid recycling bypass line.
