Xylem Water Meter Tester.

A hands-on engineering project spanning control architecture, sensors, PLC/HMI integration, electrical systems, physical testing, and rapid prototyping.

From system plan to working hardware.

This work supported a sensor-driven water-meter test system developed in an industrial R&D environment. The project required translating test requirements into control logic, hardware integration, repeatable validation procedures, and clear engineering documentation.

The resulting work improved metering accuracy by approximately 30% and reduced bench testing time from two hours to about forty minutes.

Mechanical test rig in a safety enclosure — **Mechanical test rig.** Controlled force application, alignment, fluid lines, and operator safety.

Electrical control cabinet with PLC and relays — **Electrical control panel.** PLC, relays, terminal blocks, protection, and maintainable signal routing.

Blue 3D printed structural prototype — **3D-printed prototype.** CAD-to-manufacture iteration for fit, function, and structural stability.

What this demonstrates: the ability to connect software, controls, instrumentation, CAD, physical prototyping, testing, and technical communication inside one engineering workflow.
