Product details
Principle structure
Mechanical flow switch. The stopper with built-in spring support triggers a micro motion switch when the flow rate reaches the preset value.
Product Features
Online installation, minimal pressure loss, good repeatability, anti fouling ability, precise switch settings achieved through knobs. The mechanical and electronic parts are safely isolated.
Product Application
Air, water, and oil multi-purpose type, suitable for industrial automation/mechanical equipment/air compression industry/refrigeration and air conditioning, suitable for pipelines with a diameter ≤ 50mm.
