Applications

Tips: Internal structure of magnetic water flow switch

A piston with a permanent magnet is arranged on the fluid channel inside the water flow switch housing. When the piston is pushed by the pressure difference caused by the fluid flow, the magnetic piston lead the sealing reed switch inside the device to operate. The diameter of the piston determines the starting flow rate. When the flow decreases, the stainless steel spring pushes the piston back into place. When the reed switch is actuated, it can transmit alarm or instruction remotely, or it can be integrated into the automatic control system. In addition, set the upper or lower limit for the flow switch, when the flow reaches the limit value, the flow switch will send a signal or alarm, and the system will run or stop. Flow switches are usually used in systems that require flow.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
