Flow Switch

Description

Vane type of Flow Switch utilizes the flow rate of water to drive the vane to test whether the liquid in the tube/vessel flows or not.  When the liquid in the tube/vessel does not flow, the spring presses the magnet and make the vane vertical, at this moment, the spring switch has no operation, the contact point is at “NO” state.

When the liquid flows in the tube/vessel and the flow is big enough to crash the vane.  This happens when higher to 20 to 30 degree.  It will also happen when the eccentric strap drive above the vane push the magnet upward.  Also, when the suction force of magnet make the magnetic spring switch operate, while the contact point is connected, the length of vane changes due to the diameter of pipe.

Installation

The length of vane decides the position of the operating point. Firstly, determine the length of vane according to the pipe size and the expected position of operating point. Make some mark on the vane and cut the vane (Users also can cut the length in no-mark place according to specific requirement).

The plane of vane should be installed with section of pipe in parallel and fixed on the end of thread.

Make sure that the “FLOW” mark on the product must be parallel with catheter when the installation finished. (The pipe of flow circuiting must be horizontal.)

When the float switch needs to fix on the T contact, it must be enlaced.  The enlacing is with leaking-proof belt and locked on the end of thread.
