Characteristics: Magnetic induction type; Tightness, can withstand high pressure as high as 10Mpa; Suitable for measuring a variety of clean flow liquid.

Profile:   FSB21 two-way baffle-type flow switch can measure in two ways and the range is very large. It can be used for many kinds of fluid liquid. The switch part is isolated from the media and has a better sealing capacity. FSB21 flow switch can widely used for no pressure and pressure occasions, it has a good pressure capacity which can be as high as 10MPa. It can be used to detect two-way flowing media. In the process of measurement you should pay attention that the fluid should not have so many winding debris, they would fetter the baffle, and affect the measurement. If there is no welding joint when installing, we suggest you to match steel welded joints, the dimensions and parameters of the joints can be seen in part description. The detailed parameters and structure can be seen below.

The principle of FSB21 two-way baffle-type is described as following: it can set the flow rate of action points by knob,
when the fluid flow in the pipe, the fluid will promote the baffle deflection, and the baffle will drive the magnetic modules
moving above. If the velocity of flow is greater than or equal to the setting velocity, the switch module in the chamber will
act and export contact signal. If the velocity is less than the setting velocity, the magnetic module will move down,
the switch will reset, and the joint will cut.
