The selected units of themeasured value output and sensor temperature as well as the decimal point are notinfluenced by this setting.4.2: Operating ParametersWith this parameter group, define the parameters of your vessel, the measuring mediumand the calculation of the measured signal. Signal-specific default settings such as thefailure signal or the upper current limit of the analog output signal are assigned to thefunctions of the respective outputs (see Parameters 4.3 and 4.4).4.2.1: Tank Geometry4.2.1.1: Nozzle Height = Parameter 1.34.2.1.2: Tank Height = Parameter 1.44.2.1.3: Stilling Pipe? (F = no)Stilling pipe available?By selecting yes or no, you specify whether the device is mounted on a stilling pipe. If youselect yes, Parameter 4.2.1.3.2 is enabled so you can specify the internal diameter of thestilling pipe.Value∞C∞FKValue SI unitUS/UK unitValue yesno
