Introduction
The Endress+Hauser Proline t-mass F 300 is a compact inline thermal mass flowmeter designed for accurate, direct mass flow measurement of utility and process gases in small line sizes (DN15 to DN100). Featuring a patented drift-free sensor with SIL 2 rating, it offers long-term stability and bidirectional measurement, while flexible programming for 21 standard gases and Heartbeat Technology ensure reliable, easy-to-maintain operation in diverse industrial environments.
Key advantages
1. Patented Drift-Free Sensor: With SIL 2 compliance, it delivers premium accuracy and repeatability, maintaining long-term stability without frequent recalibration for process gas applications.
2. Flexible Gas Compatibility: Supports programming for 21 standard gases or custom gas mixtures, offering versatile adaptability for various industrial utility and process gas measurement needs.
3. Bidirectional & Wide-Range Measurement: Features bidirectional flow detection with a high operable flow range, capable of monitoring both forward and reverse flow for comprehensive process control.
4. Compact & Accessible Design: The compact dual-compartment transmitter offers one-side access, touch control, and optional WLAN/remote display, simplifying installation, operation, and maintenance.
5. Integrated Diagnostics & Verification: Equipped with Heartbeat Technology and freely combinable I/Os/fieldbuses, it provides full process and diagnostic data for reliable monitoring and compliance
