AYVAZ Flow Switch 2 1/2″ (76.1mm)
Reliable flow detection and early alarm signaling for wet pipe fire protection.
The AYVAZ Flow Switch 2 1/2″ (76.1mm) provides reliable flow detection in wet pipe fire suppression systems. Moreover, its paddle mechanism senses water movement and sends a signal to the control panel. In addition, it detects flow rates between 4 and 10 gpm for early warning in sprinkler and foam systems.
This device operates only in wet pipe systems, where water flow activates the paddle. Specifically, it transmits a signal to the fire alarm panel through a dry contact, so the system responds quickly. Furthermore, it handles a working pressure of 400–450 psi and a temperature range of 0–49°C. The U-bolt connection allows fast and easy mounting on 2 1/2 inch pipes.
