Description:

Introducing the wenglor UniFlow flow sensors, expertly designed to monitor the flow rates of both aqueous and oily substances within closed piping systems Featuring a user-friendly integrated display, these sensors provide a clear indication of the switching status, making it easy to identify any maintenance needs quickly With a capability to measure without regard to flow direction, they offer unparalleled precision in their category.

The sensors also allow for seamless switching between flow measurements and medium temperature readings, accommodating temperature ranges from 0°C to 100°C, and withstanding short bursts up to 140°C.

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.
