Flow Sensor

The Flow Sensor measures the water current beneath its position and outputs a signal based on whether that current exceeds or falls below a configurable threshold. Unlike the Depth Sensor, which monitors static water levels, the Flow Sensor specifically tracks the movement of water, making it ideal for detecting river flow, pump output, and channel throughput. It costs 200 Science Points to unlock and serves as a specialized complement to the Depth Sensor in water monitoring circuits.

The Flow Sensor connects to downstream automation components through the standard signal interface. Its output can drive Floodgates, Throttling Valves, Fill Valves, Relays, and logic gates. A practical application is monitoring river flow during drought conditions: by setting the Flow Sensor to trigger when current drops below a threshold, you can automatically close Floodgates to conserve remaining water, or activate backup pumping systems. The sensor can also detect when a water channel has been blocked or when a dam has altered natural flow patterns.

For advanced water management, combine Flow Sensors with Depth Sensors and logic gates to create sophisticated monitoring networks. For example, an OR Gate connecting a low-flow sensor and a low-depth sensor can trigger emergency water conservation measures when either condition is detected. Position Flow Sensors at river channels, aqueduct junctions, and pump outlets to get a complete picture of your water network's performance. The 200 Science Point cost is identical to other basic sensors, making Flow Sensors an affordable addition to any automation toolkit. They are particularly valuable on maps with variable water sources where flow rates change dramatically between seasons.
