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 makes the vane vertical, at this moment, the spring switch has no operation, the contact point is at a “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 degrees. It will also happen when the eccentric strap drive above the vane pushes the magnet upward. Also, when the suction force of the magnet makes the magnetic spring switch operate, while the contact point is connected, the length of the vane changes due to the diameter of the pipe.
Installation
The length of the vane decides the position of the operating point. Firstly, determine the length of the vane according to the pipe size and the expected position of the operating point. Make some mark on the vane and cut the vane (Users also can cut the length in a no-mark place according to specific requirements).
The plane of vane should be installed with a section of pipe in parallel and fixed on the end of the thread.
Make sure that the “FLOW” mark on the product must be parallel with the catheter when the installation is 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 a leaking-proof belt and is locked on the end of the thread.
