Weber Sensors 4115.30 sm5/10M Flow-Captor Smart Flow Meter 4-20mA Output 24VDC (Measuring Range 0-3m/s) with 10m Cable

The adjustable flow meter Flow-captor smart meter 4115.30 sm5 with 10m Cable

The smart meter 4115.30 sm5 is specifically used for measuring and control tasks. The smart meter operates fully electronically without moving parts. Regardless of flow properties the smart meter can be used for pipe diameters up to 24" (600mm). Even very low flow rates are measured with high accuracy.

The smart meter operates to the calorimetric principle. The sensor head of the flowcaptor contains two PT-resistors. One of them is measuring the temperature of the media, while the other is heated by an attached heating resistor, resulting in a temperature difference between the two PT-resistors. The temperature difference between the two PT-resistors is predetermined and a control circuit keeps this temperature difference constant. The flow of the media cools the heated PT-resistor proportional to the speed of the flow. The heating power fed into the system by the control circuit, in order to keep the temperature difference between the two PT-resistors constant, is the equivalent to the heat dissipation by the flow of the media. This results in a linear output signal proportional to the flow speed.

The immersion depth of the flow-captor is infinitely adjustable. The sensor is simply screwed into the existing flange or nipple and set a few steps to the optimum depth of immersion.
