Seastream Venturi

The most robust and widely used solution for water and injection applications.

Seastream Venturi are designed to offer high accuracy and reliable operation even in the harshest of subsea environments. These meters are supported by the ISO5167 international flow measurement standard and recognized as a robust ‘Fit and Forget' flow metering solution. Each meter is designed for a unique project application and supplied in a variety of materials to suit individual operator specifications.

  • Improve Hydrocarbon Recovery
  • High Accuracy
  • Robust & Reliable Data
  • Fully Redundant Sensors
  • MODBUS/SIIS/IWIS Capable


Specialist Solutions
The introduction of the new in-head flow calculator removes uncertainty from integration into subsea systems, while reducing client software programming time. The ability to include a flow calibration curve within the calculation can further enhance the accuracy of the Seastream.

Close Coupled Diaphragm Seal Technology transferring the measurement closer to the process and is available for gas applications, reducing the possibilities of hydrate formation.

Fly to place instrumentation is available to enhance meter reliability

  • NO Control System Calculation Required
  • Close Couple Sensor Option
  • Fly to Place Instruments

Applications
The Seastream is designed particularly for Well Management and flow assurance Gas Lift and Water Injection applications but can be adapted for any single phase application.
  • Water Injection
  • Gas Injection
  • Gas Lift
