Throughput Monitor & Flow Meter

Take control of your logistics with precise, real-time data tracking. This mod introduces three specialized meter types (Loose, Fluid, and Flat) to monitor your production lines with professional-grade accuracy.

Key Features:

  • Triple Meter Support: Dedicated units for Loose products, Fluids, and Flat/Boxed items to cover all types of cargo.
  • Ground & Elevated Placement: Build your meters exactly where you need them. Fully supports multi-level factory designs, allowing meters to be placed mid-air with automatic physical pillar spawning.
  • Historical Trends & Interactive Charts: A floating historical trend dashboard instantly appears when hovering your mouse over any product icon. Hover over the chart's bars to view exact 12-month and 12-year historical throughput data.
  • Granular & Smooth Statistics: View perfectly stabilized Monthly Averages, Yearly Averages, and Lifetime Totals for every item passing through the meter.
  • Multi-Product Tracking: Effortlessly handles mixed-resource belts by tracking individual product data and overall statistics within one unified, clear UI.
  • Manual Reset Control: A dedicated reset button allows you to instantly clear historical statistics when reconfiguring your production lines.
  • Unlimited Throughput: Designed specifically for high-performance logistics monitoring with minimal impact on the game's simulation thread.

We’ve completely overhauled the UI and placement mechanics to give you a true industrial control experience.

  • Interactive Dual-Charts: Hover over any product to reveal a sleek, dynamically scaling floating dashboard. Check your exact 12-month and 12-year throughput trends at a glance!

  • Mid-Air Building: Need a flow meter on your 3rd-floor pipeline? You can now build meters elevated in the air with automatic physical pillar spawning.

  • Smoother Analytics: New behind-the-scenes math ensures your averages stay rock-solid and perfectly stabilized, eliminating jumpy data at the start of a new month.

  • Seamless Upgrading: Your saved history data is 100% compatible with your existing savegames!
