Product Introduction
The F3RO Pulse Flow Meter by Gentos is a non-invasive clip-on ultrasonic flow meter for industrial use. It measures fluid flow accurately using transit time technology and Gentos' patented algorithm. Easy to install without pipe damage or shutdown, it features a 1.44" LCD screen and supports RS485, OCT pulse, and relay outputs. Suitable for DN20-DN80 pipes of carbon steel, stainless steel, copper, and PVC, it offers ±2% accuracy (0.3-5 m/s) and a 0-60°C temperature range. With IP54 protection, the F3RO ensures reliable monitoring in HVAC, water treatment, and agriculture.
