Wiring diagram

Tips: What are the factors that cause the measurement error of the tuning fork density meter?

Temperature: Temperature will affect the elastic modulus of the resonant element and other mechanical structures such as length and thickness changes.
Liquid flow: Due to the frictional force of liquid flow, the pipe wall is subjected to shear force, which will affect the change of resonance frequency.
Dirt pollution: If there is dirt inside, it will inevitably change the resonance period.

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.
