Advanced Flow Control & Monitor
Take control of your logistics with precise flow monitoring, historical data, alarms, and active throughput control.
The mod adds three specialised meter types for Loose, Fluid, and Flat/Boxed cargo, giving you detailed production data and the tools to actively control your factory's flow.
Key Features
- Active Flow Regulation – Set a target flow rate and let the meter automatically limit throughput between the input and output.
- Flow Alerts – Set custom Low and High Flow alarms with limits from 0% to 75% and from 100% to 200% of the target. Alerts use the game's native notification system.
- Historical Charts – Hover over a product icon to open its history. View 12-month and 12-year throughput data and hover over chart bars for exact values.
- Detailed Statistics – Track Monthly Average, Yearly Average, and Lifetime throughput. Mixed-product belts are supported, with separate statistics for each product.
- Three Meter Types – Dedicated meters for Loose, Fluid, and Flat/Boxed cargo.
- Ground & Elevated Placement – Place meters on the ground or directly in elevated factory lines. Elevated meters automatically spawn the required support pillars.
- Automatic Setpoints – New meters automatically detect the maximum throughput of connected conveyors and use it as the initial target flow rate.
- Global Localisation – Built-in translations for Russian, French, Simplified Chinese, Greek, German, Spanish, and Brazilian Portuguese. Translation
.jsonfiles are included for community edits and additional languages. Many thanks to @Hoochie for the Russian translation. - Performance & Controls – Designed to minimise impact on the game simulation. Includes a reset button for quickly clearing historical data when reconfiguring production lines.
Monitor. Control. Optimise.






## Flow Control & Monitor v0.3.0 is Live!
I'm excited to release the v0.3.0 update for Flow Control & Monitor (formerly Throughput Monitor & Flow Meter)! This major update turns the mod from a simple stats screen into an active tool for managing and throttling your factory's belts and pipes.
Here is a breakdown of the new features:
Active Flow Control
You're not just watching the items anymore—you can actually control the speed.

The Flowregulator Panel: As shown in the picture, you can now type in an exact target flow rate right in the UI.
Active Throttling: Tick the "Regulate the flow" box, and the meter will automatically throttle the belt or pipe to perfectly match your target.
Smart Pause Button: You can now use the pause button on the UI to completely halt the conveyor. It allows you to pause the machine in a way that won't ruin your historical flow rate statistics!
Smart Defaults: When you place a new meter (or load an old save), it automatically sets the target to the max speed of the connected belts so it doesn't accidentally bottleneck your factory.
Custom Flow Alerts
Never miss a jammed belt or an empty pipe again.

Custom Triggers: Set up low and high flow alerts using the new bell menu. You can set triggers anywhere from
< 0%(No Flow) up to> 200%of your target speed.Game Notifications: These alerts tie straight into the base game's UI. If a line backs up, you'll get a popup telling you exactly which product is having issues.

Anti-Spam (Hysteresis): Added a 2% buffer to the code so your alerts don't rapidly spam on and off if the flow is hovering right on the edge of your limit.
Translations & Multi-Language Support
New Languages: Added full support for Russian, French, Simplified Chinese, Greek, German, Spanish, and Brazilian Portuguese.
Modder Friendly: The translation
.jsonfiles are included right in the mod folder. If you want to fix a typo or add your own language, just open them in a text editor and tweak away!
Thanks for all the feedback and support!
The Elevated Placement & History Data update is officially here!
We’ve completely overhauled the UI and placement mechanics to give you a true industrial control experience.
What's New in v0.2.0:
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!
FlowMeter Realease v0.1.1
Thank you for your feedback! I’m happy to share the latest update for the mod.
The main changes in the version v0.1.1 are:
FIX: Flowmeter now correctly highlights when selected.
FIX: Addressed visual glitches where the flowmeter appeared partially built during the construction/prototyping.
FIX: Maintenance panel now correctly initializes when the mod is added to existing save games.
FIX: Resolved "Null Proto ID" warnings in the game log.
MPROVED: Redesigned maintenance idle check: the flowmeter now consumes higher maintenance while actively processing product (idle timeout: >1 second of inactivity).
ADDED: Highest game version the mod has been tested with.
