The flow indicator employs a tapered nut to adjust sensitivity, ensuring reliable operation. A rubber diaphragm assembly connects the paddle, delivering excellent assembly processability and sealing performance. Installed on the main water pipe or cross-branch pipe, it utilizes plate-type blades within the water supply network to convert flow signals into electrical signals. These signals indicate water movement within a specific zone, transmitting to the control box to trigger alarms or activate control switches for fire pumps.
