Industry Insight:
Why Flow Monitoring Matters
Water districts today are under growing pressure to combat water scarcity and reduce system losses. Monitoring flow between distribution zones has become critical for optimizing resource management — but traditional flow meter installations are often cost-prohibitive. AccuPos offers a practical, cost-effective alternative, delivering the same insights through precise valve position feedback.
Real-World Applications
The AccuPos Valve Position Sensor is designed to integrate seamlessly into a variety of automation environments and system architectures.
Valve Position Feedback
Provides accurate valve position data during real-time operation for better process control.
SCADA System Integration
Provides accurate valve position data during real-time operation for better process control.
Diaphragm Valve Compatibility
Easily mounts to diaphragm valves with stem kits—no complex mechanical linkage required.
Control Panel Applications
Ideal for use in control panel builds, offering simple wiring and reliable feedback integration.
Flow Meter Alternative
Cost-effective replacement for flow meters in certain applications where position feedback is sufficient.
Remote Site Automation
Reliable performance for remote and standalone sites with minimal maintenance requirements.

Cost Comparison: AccuPos vs Traditional Flow Meters
Smarter Savings Without Compromise
Traditional flow meter installations can cost over $40,000 per unit—making them impractical for many applications. In contrast, AccuPos delivers the same valve position and flow data for a fraction of the cost.
One five-valve pressure reducing vault installation using AccuPos saved a client over $130,000 in parts and labor compared to a traditional flow meter setup.
Real-World Savings Example:
A better solution, at a better value—without sacrificing reliability or performance.
