2540/2541/2517 high performance flow sensors are a flow sensor measuring range of 0.1-6m/s, with 316SS or copper structure, can measure flow rate below 0.1m/s, with standard NPT or ISO process connection, hot-tap type installation/operation without system shutdown.
The document provides an overview of the GF+SI high‑performance flow sensors (models 2540, 2541, and 2517). It describes their applications in HVAC, water distribution, and other fluid‑handling systems, and highlights key features such as low‑flow measurement down to 0.1 m/s and robust 316 SS construction.
Detailed installation instructions are included, covering pipe size options (1.5 in NPT, DIN 40‑600 for standard and 40‑1000 for Hot‑Tap), mounting orientation, and wiring connections. Technical specifications such as flow range, accuracy, pressure limits, and material details are also listed. This manual is written in Chinese.

The 2540 and 2541 sensors measure flow from 0.1 m/s up to 6 m/s.
The sensors can operate up to 17 bar at 82 °C for NPT models and up to 17 bar at 100 °C for Hot‑Tap models.
The body of the 2540/2541 sensors is made of 316 stainless steel, while the 2517 model uses C36000 material.
