Engelmann – FlowStar U PN25 – Ultrasonic Bulk Water & Thermal Flow Meter
Description:
The Engelmann FlowStar U PN25 is a high-performance ultrasonic flow meter engineered for accurate and reliable flow measurement in high-pressure water, heating, cooling, and HVAC systems. Designed for demanding commercial and industrial applications, the FlowStar U utilizes advanced double-channel ultrasonic measurement technology to deliver highly precise bulk water and thermal flow monitoring.
Built with a robust stainless steel body and PN25 pressure-rated flanged connections, the FlowStar U is ideal for high-pressure circulation systems, plant rooms, district energy networks, chilled water systems, condenser water systems, and large-scale bulk water monitoring applications.
The FlowStar U measures water flow with exceptional accuracy and can also be integrated with temperature sensors and a compatible energy calculator such as the Engelmann SensoStar C to calculate thermal energy consumption in heating and cooling systems.
With IP68 environmental protection, flexible installation options, and sizes ranging from DN50 to DN300, the FlowStar U offers a reliable long-term metering solution for modern industrial and commercial infrastructure projects.
