IFM Efector Air Flow Meters

Overview

The IFM EFECTOR u40100 is a complete flow sensor and evaluation unit designed for reliable monitoring of liquids and gases in pipe systems. The unit integrates flow measurement, temperature sensing, and wire-break monitoring into a single device, reducing the number of components required in a monitoring circuit. Switching outputs are field-adjustable, allowing technicians to set trip points for both flow and temperature without additional controllers. Signal output is delivered through potential-free relay contacts, making the unit compatible with a wide range of control systems and PLCs. Industrial instrumentation technicians and process control professionals are the primary installers of this device. The u40100 is suited for residential and commercial HVAC systems, industrial process piping, and fluid handling applications where continuous flow and temperature supervision is required. Typical installations include chilled water systems, cooling loops, and gas distribution lines where loss-of-flow or out-of-range temperature conditions must trigger a control response. The multi-color LED bargraph display provides an at-a-glance visual indication of current process conditions directly at the sensor, reducing diagnostic time during commissioning and service calls.
