Page 27: Signal Outputs
The device has an analog output of 4 ... 20 mA. This output can be scaled to match the desired measuring range. Standard scaling is from 0 to max flow. The S401 can be ordered with the bi-directional calibration. In such case, the correspondence between the analog output and standard scaling is as follows:... - Page 28 10 Signal Outputs In case that the flow rate is too high, the S401 cannot output the pulses with default settings (one pulse per consumption unit). In this case, you can set the pulse to 1 pulse per 10 consumption units or 1 pulse per 100 consumption units, using the S4C-FS service app or a connected display.
