This way you can easily and quickly set up therequested flow through the valve.Once the value of requested flow is entered, the flow value in absolute units / the percentage ratiofrom the previous paragraph will be displayed in the Flow field in the Measuring screen.If you set up the requested flow value back to zero,the Flow field in the Measuring window will showjust the flow value in absolute units.Measuring (continuous)Medium TemperatureSpecify the temperature of the medium in the measured system by pressing the SetTemperatureselection list.Fill in the temperature data manually in the Temperature field.For water medium, the effect of the temperature on the flow calculation is negligible. If an anti-freeze isselected as the medium, the temperature specification is necessary for the flow calculation!!!
