Fluid injection system

A system, comprising:

• a sub-sea retrievable module, comprising:
• a housing having a fluid inlet, a fluid outlet, and a flow path between the fluid inlet and the fluid outlet;
• a non-invasive flow meter system disposed in the housing along the flow path, wherein the non-invasive flow meter system is configured to measure a fluid flow of a fluid along the flow path;
• and
• a pressure measurement system disposed in the housing along the flow path, wherein the pressure measurement system is configured to measure a fluid pressure along the flow path, and the system is configured to determine the fluid flow of the fluid along the flow path based on a measurement by the pressure measurement system.

A system, comprising:

• a sub-sea retrievable module, comprising:
• a housing having a fluid inlet, a fluid outlet, and a flow path between the fluid inlet and the fluid outlet;
• an adjustable valve disposed in the housing along the flow path, wherein the adjustable valve is configured to control a fluid flow of a fluid along the flow path;
• a pressure measurement system disposed in the housing along the flow path, wherein the pressure measurement system is configured to measure a fluid pressure along the flow path;
• and
• a sensor disposed in the housing along the flow path, wherein the sensor is configured to measure a parameter of the adjustable valve or a valve actuator, and the system is configured to determine the fluid flow of the fluid along the flow path based on the fluid pressure and the parameter.

A system, comprising:

• a sub-sea retrievable module, comprising:
• a housing having a fluid inlet, a fluid outlet, and a flow path between the fluid inlet and the fluid outlet;
• and
• an adjustable valve disposed in the housing along the flow path, wherein the adjustable valve is configured to control a fluid flow of a fluid along the flow path;
• an electric valve actuator disposed in the housing along the flow path, wherein the electric valve actuator is coupled to the adjustable valve;
• and
• a first measurement system disposed in the housing along the flow path, wherein the first measurement system is configured to measure a first parameter along the flow path;
