Description:

Introducing the UniFlow Flow Sensor by Wenglor, expertly engineered to monitor the flow rates of both aqueous and oily substances within closed piping systems With an integrated display, this sensor simplifies operation and offers a clear view of the switching status, allowing for quick identification of sensors that may require maintenance The UniFlow stands out with its capability to measure flow rates without regard to flow direction, all while delivering unparalleled precision.

Users can easily toggle between flow rate and medium temperature readings, and the device allows for a customizable measurement range Operating efficiently within a medium temperature range of 0 to 60°C, it can withstand exceptionally high temperatures of up to 140°C for a duration of 24 hours without affecting current measurements This advanced feature set makes the UniFlow Flow Sensor an invaluable tool for any closed piping system.

Features and Benefits:

    •Measurement independent of flow direction.

    •Highest precision of its class.

    •Display can be switched between flow and medium temperature.

    •Selectable measuring range.

    •Temperature of the medium: 0 ... 60° C (140° C for 24 hours without current measurement).
