    wenglor UniFlow flow sensors measure the flow rate of aqueous and oily media in closed piping systems.

    UniFlow flow sensors are very easy to operate thanks to the integrated display. The highly visible switching status display enables the rapid localization of affected sensors for maintenance processes.

    • Measurement independent of flow direction
    • Highest precision of its class
    • Display can be switched between flow and medium temperature
    • Temperature of the medium: 0 ... 100° C (140° C for 24 hours without current measurement)
    • Selectable measuring range
