Installation Instructions

When piping the gear flow sensor, use a wrench to pipe the metal part (pipe fittings) that is integrated with the piping. If a wrench is used on other parts, the flow switch may be damaged. In particular, a wrench cannot be used on the M12 connector. Otherwise, the connector may be damaged.

Note: Do not allow the sealing tape to mix into the pipe when installing the piping. Do not allow the piping to leak due to looseness when connecting. If tightening beyond the tightening torque range, the switch may be damaged. If assembled with less than the specified tightening torque, the connection thread may loosen.

Applications

Tips: Working principle of gear flow sensor

Gear flow sensor is a flow meter that measures volume flow with high precision. Its working principle is the positive displacement principle. The flow of the medium causes the gear to rotate. The rotation of the gear drives the rotation of the magnetic pole, which is then scanned by the non-contact Hall sensor. Continuous rotation scanning generates continuous pulses, and finally generates a frequency signal that is proportional to the flow, and then the flow value is obtained. This gear liquid flow sensor based on the standard volumetric principle has a pair of meshing gears as rotors in the cavity. The two gears and the cavity can each form a fixed volume, called the standard volume. The flow rate is measured by calculating the number of flows that pass through the standard volume within a certain period of time.

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.
