Subsea Instrumentation

Flow meters, pumps, pressure, level, and temperature transmitters are critical components in Subsea Instrumentation systems utilized in the offshore oil and gas industry. Here are a few examples of the usage of these instruments in the subsea industry:

Flow meters

Subsea Instrumentation, including Flow meters, measures the flow rate of fluids like oil and gas in subsea pipelines. Accurate flow measurement is essential to ensure the safe and efficient operation of the system, optimize production rates, and prevent costly spills or leaks. These sensors measure the pressure of the surrounding water or fluid in subsea environments. Also, they can provide data for monitoring and controlling various subsea operations. Finally, these instruments measure the flow rate of fluids, such as oil or gas, in subsea pipelines. They are crucial for monitoring production rates and optimizing flow efficiency.


Pumps transport fluids, like oil and gas, from subsea wells to the surface. Ensuring proper pump operation and control is crucial to deliver the right amount of fluid to the surface and to maintain optimal system pressure and flow rates.

Pressure transmitters

Pressure transmitters monitor the pressure of fluids in the subsea pipelines and equipment. Accurate pressure measurement is essential to ensure the safe and efficient operation of the system and to prevent equipment damage. In addition, these sensors measure the pressure of the surrounding water or fluid in subsea environments. Finally, they can provide data for monitoring and controlling various subsea operations.

Level transmitters

Level transmitters monitor the level of fluids in subsea storage tanks and equipment. Accurate level measurement is critical to ensure that the system has enough fluid and to prevent equipment damage due to low fluid levels.

Temperature transmitters

Temperature transmitters monitor the temperature of fluids in subsea pipelines and equipment. Accurate temperature measurement is essential for maintaining the system’s proper operation and preventing damage to the equipment due to extreme temperatures. Moreover, these sensors measure the temperature of the fluids or surrounding environment in subsea applications. Finally, they help ensure the safe and efficient operation of subsea equipment.

In summary, flow meters, pumps, pressure transmitters, level transmitters, and temperature transmitters are essential instruments in the subsea industry. They are essential for measuring and controlling fluid flows, pressures, levels, and temperatures. Also, these instruments help to ensure safe and efficient operation. They also prevent equipment damage and optimize production rates in the offshore oil and gas industry.

Advantages and Disadvantages of each type of subsea instrumentation

Pressure Sensors:

  • Advantages: Provide vital data for monitoring and control of subsea operations, and help ensure equipment integrity and safety by detecting pressure anomalies.
  • Disadvantages include the potential need for frequent calibration and maintenance, as well as susceptibility to fouling or blockages in the subsea environment.

Temperature Sensors:

  • Advantages: Essential for maintaining optimal operating conditions contribute to the safety and efficiency of subsea equipment.
  • Disadvantages may include susceptibility to drift or inaccuracies over time, alongside vulnerability to fouling or insulation issues.

Flow Meters:

  • Advantages: Enable accurate monitoring of fluid flow rates, and help optimize production and resource management.
  • Disadvantages: Susceptible to fouling or blockages, and may require periodic calibration and maintenance.

It’s important to consider specific project requirements, environmental conditions, and maintenance considerations when selecting subsea instrumentation. Besides, regular maintenance, calibration, and monitoring are often necessary to ensure accurate and reliable measurements.

Scenarios and Applications

Regardless of whether for subsea penetrating activities, ROV support, or subsea synthetic infusion SRS’s subsea stream meters are capable. Your offshore operational processes demand the most reliable, highest-precision instruments – ones designed for harsh subsea conditions. SRS’s estimation gives us the certainty to handle your hardest subsea applications.

Control Valve Application

Blowout Preventers (BOPs) are huge, submerged control valves used to “forestall” the uncontrolled arrival of weight or flow of fluids during great penetrating activities or creation. One can remotely control these water-powered valves to close or open a well to prevent a blowout, and they are typically installed in series as a safety measure.

Keeping up the BOP and ceaselessly testing it is an extremely high need of both the oil organization and penetrating temporary workers. Turbine flow meters monitor the hydraulic fluid to these valves to ensure their proper operation when needed.

Maintenance of Flow Meters

Remote Operated Vehicles (ROVs) are utilized for some control, assessment, and support of subsea capacities to wellheads, subsea trees, umbilical links, and marine risers. Also, the ROV is fueled by a powerful electric engine that drives a pressure-driven siphon. It then stays fastened to a host transport during subsea activity.  Turbine flow meters are installed for close monitoring of the hydraulic fluid flowing through the variety of systems in the ROV. For example, impetus, force instruments, and controller’s arms.

Chemical Injection for Flow Meters

When oil is pumped out of the subsea well, various chemicals and additives are injected into the flow to ensure the highest efficiency possible.  By and large, oil organizations will introduce flow meters to gauge these synthetics for the passage. This passage is regularly well underneath the surface, rather than outdoors where the liquid needs to travel a huge span down before entering the stream.

Regularly this is a savvier method for estimation. Positive Displacement (PD) flow meters are utilized for injecting additives like mono-ethylene glycol (MEG), methanol, and low-dose inhibitors (LDIs).
