About Vestala Oceanus
A specialist partner for fiscal-grade flow measurement.
Vestala Oceanus Flow Management System Pvt. Ltd. designs, fabricates and commissions custody transfer, metering and industrial automation packages for the global energy sector.
Our mission
Deliver the most accurate, reliable and audit-ready measurement systems in the industry.
Our vision
To be the engineering partner of choice for hydrocarbon custody transfer worldwide.
The manifesto
Three principles behind every package we ship.
01
Measure what matters
Fiscal measurement is the moment value changes hands. We engineer that moment to be beyond dispute — every barrel accounted for, every ticket traceable.
02
Prove it, continuously
Accuracy is not a certificate on a wall. Our systems prove themselves in line, on demand, against the international standards operators audit against.
03
Build for decades
A metering package should outlive the project team that commissioned it. We fabricate, document and support for the full lifecycle of the asset.
Solutions portfolio
Complete measurement, engineered end-to-end.
From specification and fabrication to commissioning and lifecycle support — built on international standards.
02
Flow Metering
Coriolis, turbine, ultrasonic and positive-displacement packages engineered to API MPMS standards.

How a LACT system works
Eight steps from inlet to invoice.
Every custody transfer follows the same audited sequence — condition the fluid, measure it, prove it, sample it, record it. The cycle below runs continuously on every skid we ship.
STEP 01 / 08 · RECEIPT
Inlet
Crude or refined hydrocarbon enters the LACT skid from the lease, pipeline or terminal header.
