Claim:
1. An electrical submersible pump assembly, comprising: a centrifugal pump; an electrical motor operatively coupled to the pump; a seal section disposed between the pump and the motor for sealing lubricant within the motor; at least one instrument sub releasably secured to one end of the pump above an intake of the pump; at least one pump stage in the at least one instrument sub, the at least one pump stage comprising an impeller and a diffuser configured for pumping well fluid; at least one sensor within the at least one instrument sub for monitoring parameters in the at least one instrument sub; a motor lead having power conductors, the motor lead being connected to an upper end of the motor and extending alongside the seal section, the at least one instrument sub and the pump; at least one sensor line extending sealingly through a sensor line port in the at least one instrument sub to the at least one sensor for conveying sensed information from the at least one sensor to a remote instrument panel; and the at least one sensor line bundling with and extending alongside the power conductors of the motor lead upward from the at least one instrument sub.
