This exclusive feature allows simple removal of the existing scales and easy mounting of additional scales for different fluids and flow rates. In addition, these versatile meters offer quick conversion from factory-set panel mounting to partial or full in-line configurations by correspondingly exchanging the Plug Seals and the Inlet/Outlet Connectors.
