Measuring wellbore fluid characteristics in a wellbore

A method for producing wellbore fluids from a wellbore, comprising:

• running a downhole pumping system into a wellbore that extends from a terranean surface to a subterranean formation on a downhole conveyance, the downhole pumping system comprising:
• a downhole pump;
• a motor module coupled to the downhole pump;
• a flowmeter coupled to the downhole pump;
• and
• a motor hub coupled to the downhole pump and the motor module,
• running the downhole pumping system into the wellbore with at least a portion of a power line communication cable attached to a motor lead extension that is electrically coupled between the motor hub and a power source on the terranean surface;
• supplying primary electrical power from the terranean surface to the motor module through the motor hub;
• operating the downhole pump with the motor module upon receipt of the primary electrical power to circulate a wellbore fluid from the wellbore, through the downhole pump, and to the terranean surface;
• and
• during operation of the downhole pump:
• generating secondary electrical power from the primary electrical power with the motor hub,
• supplying the secondary electrical power from the motor hub to the flowmeter,
• operating the flowmeter on the secondary electrical power to measure one or more flow characteristics of the wellbore fluid;
• and
• supplying the secondary electrical power from the motor hub to the flowmeter on the power line communication cable.
