Virtual Flow Meter
An industrial application based on sensor data and soft-sensing regression models, used to estimate fluid flow in scenarios such as oil wells. It enables real-time monitoring without a physical flow meter.
Timeline (last 90 days)
A virtual flow meter is a steady-state soft-sensor regression model that estimates oil well flow from sensor data, and it is a typical industrial-grade application scenario.
The experiments were conducted on a synthetic oil and gas dataset, and when filtering using only sensor data, the downstream model's MAPE was 7.1%.
After adding operator text comments on top of the sensor data, the downstream model's MAPE dropped from 7.1% to 5.4%, a decrease of 1.7 percentage points.
A MAPE decrease of 1.7 percentage points is a significant improvement for a soft-sensor model and typically corresponds to considerable economic benefit.
