Subsea Venturi Flow Meter - Sensor’s For Water & Gas Injection

Seastream Venturi flow meters, commonly referred to as SPFM’s (single phase flow meters), provide high accuracy and reliable flow measurement data in the harshest of subsea environments. Our gas lift, gas and water injection flow meters, supported by the ISO5167 international flow measurement standard, are recognized as a robust ‘fit and forget’ injection metering solution.

Next Generation

The latest compact design Seastream has been re-engineered to reduce CAPEX, lead time and benefit from standardized documentation.

Reliability & Performance

The sensor at the heart of our subsea flow meters consists of a resonating silicon crystal that provides a truly digital measurement from the process to the clients' control system. The digital operation ensures our Venturi offer class-leading accuracy, stability and operating range (turn down) essential to minimise intervention and enable efficient reservoir recovery over the life of the field. Our 'FloCalculator' uniquely provides a direct flow rate output only available on Seastream 


A Valued Track Record

Seastream has been operating in water depths down to 10,000ft (3000m) since the earlier 1990s providing valuable data to reservoir engineers across the worlds major and independent energy companies.

Quality & Environment

Solartron subsea hardware and sensors are built to robust quality standards, we are ISO9001:2015 certified and compliant with API 6A, API 17D and API 17F. Data from our meters can help reservoir engineers produce hydrocarbons more efficiently, therefore, reducing the environmental impact during energy production and our accreditation to ISO45001:2108 & ISO14001 ensures we manufacture responsibly.

One Concept For All Injection Applications

Seastream is available for 2 1/16th and 5 1/8" line sizes for gas lift, water or gas injection (including WAG) and chemical injection applications. API 10,000psi ratings are available. Alternate Venturi line sizes and rating are possible by special request.
