Virtual Metering Systems

Measure without the meter.

Virtual meters infer flows, compositions and other quantities from the instrumentation you already have: model-based estimates, validated against test data, running continuously. Proven practice from major LNG pipeline projects, brought to your operation.

Software sensors that measure what hardware can't, or shouldn't have to.

• Model-based measurement Physics-based and data-driven models that estimate flow rates and stream properties from pressures, temperatures and the meters you already have.
• Allocation & reconciliation Consistent, defensible estimates where physical metering is impractical, feeding allocation and balance calculations.
• Backup for physical meters Virtual meters run alongside hardware, flagging drift and covering outages so measurement never goes dark.
• Continuous validation Estimates tracked against well tests and meter proving, with confidence reported rather than implied.
• Deviation alerts When reality and model disagree, someone finds out. That disagreement is often the first sign of a real problem.

FAQ

How accurate is a virtual meter?

It depends on your instrumentation and the model. We quantify accuracy against reference data during commissioning and report confidence continuously, so you know exactly what you're relying on.

Does it replace physical metering?

Sometimes. More often it complements it: covering gaps, backing up critical meters and extending measurement where hardware isn't justified.

What inputs does it need?

Your existing instrumentation: pressures, temperatures and available meters, usually via your historian. Discovery includes an instrumentation review.
