Leak Detection: How It Works
You’ll be alerted when the system detects flows that match configured leak profiles or when a leak detector senses moisture. The system supports multiple detection strategies to catch both sudden breaks and slow leaks.
Detection methods available
You’ll use threshold-based detection (X gallons/hour), duration-based detection (continuous flow longer than Y minutes), and remote leak detectors that sense moisture. Combined, these reduce false alarms while catching real issues quickly.
Auto-Shutoff Functionality
The core safety feature is automatic shutoff. When the system detects a leak according to your rules—or when a detector is triggered—it can shut off the main valve to prevent damage.
How the auto-shutoff behaves
You’ll have options to customize triggers: shut off on persistent flow, sudden large flows, or manual triggers from the app. The unit’s local controller can close the valve even if your internet or power is down, ensuring protection in critical situations.
Offline Protection and Resilience
You’ll appreciate that the system can protect your home even during outages. Offline operation is enabled by default, meaning local logic handles emergency shutoffs when the hub or cloud is unreachable.
What stays functional during outages
The meter’s local logic and valve actuator are designed to operate independently of cloud services. You’ll still get automatic shutoff for configured thresholds and manual valve control directly at the unit if needed.
Valve Automation, Scheduling, and Manual Control
You’ll be able to schedule regular valve closures, create timers, and open or close the valve manually via the app or by hand.
Practical scheduling scenarios
You’ll set the valve to close during extended absences or overnight if you have a pool fill or irrigation system. You can also automate valve cycles for maintenance or to test valve responsiveness at low usage times.
Built-In Valve Maintenance
The FlowSmart includes scheduled maintenance cycles that exercise the valve to reduce the risk of seizing or mineral buildup. This extends the valve’s life and helps ensure readiness in an emergency.
Why scheduled maintenance is useful
You’ll avoid stuck valves and unexpected failures because the system automatically cycles the valve occasionally. This reduces the need for manual testing and ensures the actuator remains functional.
Temperature Monitoring and Alerts
You’ll get high and low temperature alerts, adding freeze protection and preventing damage due to extremes. This is especially useful if pipes run through unheated areas.
How temperature alerts help
You’ll receive notifications if temps approach freezing or soar to damaging levels, so you can take action before pipes burst or equipment fails. Temperature tracking adds another layer of protection for seasonal changes.
Data Export and Analysis
You’ll be able to export your water usage data for further analysis. This helps if you’re tracking bills, verifying usage claims, or trying to isolate the cause of a spike.
Export formats and use cases
You’ll typically export CSV or XLS files that feed into spreadsheets or home automation platforms. Use exported data to find trends, share with plumbers, or build custom reports.
Performance and Accuracy
You’ll find the ultrasonic meter provides high accuracy across a wide flow range. Ultrasonic measurement avoids mechanical wear and is less prone to clogging or drift compared to traditional turbine meters.
Accuracy in everyday use
You’ll see precise readings for slow flows (helpful for drip detection) and for higher flows during irrigation or filling tasks. Stabilized readings with minimal lag make the system reliable for both monitoring and automatic shutoff decisions.
Battery Life and Power Considerations
The meter boasts a 10-year battery life under typical usage assumptions, which is a major convenience. The leak detectors also have long battery life but may require periodic replacement depending on activity and signal strength.
What affects battery lifespan
You’ll find that frequent valve actuations, heavy radio use, and extreme temperatures can reduce battery life. Still, the long-life design minimizes maintenance needs and the app warns you when batteries run low.
Reliability and Redundancy
You’ll appreciate the system’s redundant protection: local logic for shutoff, physical manual control, and remote alerts. This layered approach reduces single points of failure.
How redundancy protects you
If the cloud service or Wi-Fi goes down, the meter still closes the valve autonomously according to local rules. You’ll also be able to actuate the valve manually, offering a fallback if electronics fail.
Practical Use Cases
You’ll find multiple real-world scenarios where this product adds value—from preventing catastrophic leaks while you’re away to tracking water use for billing or conservation.
Typical scenarios where it shines
You’ll use it when leaving home for vacation, when you want to control irrigation remotely, when you lease property, or when you’ve previously had water damage issues. It’s also useful for renters with permission or homeowners who want to audit family water habits.
