IFW5 Series structure and operating principle diagram
Operating Principle
When water flows, a differential pressure is generated before and after the orifice at the port of body 1. This differential pressure is detected by a pair of upper and lower diaphragms, rod 2 is displaced downward, operating lever 4 is lowered, and the micro switch is turned on.
If the flow rate is increased, the rod will be displaced downwards by 2, and if it is decreased, it will be displaced upwards. In addition, the adjustment gear 5 can be rotated and the gear 3 can be moved vertically to detect signals at any flow rate.
