Key advantages and benefits of flow-captor 442x.1xM/xx

  • Inline flow switch: The flow-captor 442x.1xM/xx serves as an efficient inline flow switch, providing real-time monitoring and control for both water and oil-based solutions.

  • High accuracy under low flow conditions: Even under the most challenging low flow conditions, this device maintains high accuracy, ensuring reliable performance in diverse operational scenarios.

  • Separate adjustment for "range" and "set-point": The flow-captor allows users to precisely adjust both the "range" and "set-point," providing flexibility in tailoring the device to specific flow requirements.

  • Analog display of flow rate: With an analog display, the 442x.1xM/xx offers a clear and real-time representation of the actual flow rate, facilitating immediate visual assessment.

  • Temperature sensing capability: Equipped with an additional PT100 temperature detecting element, this flow switch goes beyond flow monitoring by enabling the determination of the required temperature set point, adding an extra layer of functionality to your system.

Flow Captor 4420 Xxmxx Overview

Calorimetric Measuring Principle: Precision Flow Detection with Weber Sensors

The sensor employs the calorimetric measuring principle, a technique that involves the precise detection of flow velocity within the inline tube. This process is facilitated by the sensor's ability to accurately gauge the heat generated by the flowing medium.

As the liquid passes through the tube, the sensor registers variations in temperature, allowing it to calculate the speed of the flow with remarkable precision. Subsequently, these temperature-related measurements with the advantage of no mechanically moved parts are transformed into an electrical signal.

This innovative approach ensures reliable and responsive monitoring of fluid dynamics in industrial applications.
