4.1.4: Temperature Unit (F = °C)
Unit of the sensor temperature
Value
4.1.5: Other units (F = SI)
Units system for all other units
Value
With this function, determine whether you want to enter the operating parameters (see
Parameter 4.2) in SI or in British Imperial (US/UK) units. The selected units of the
measured value output and sensor temperature as well as the decimal point are not
influenced by this setting.
4.2: Operating Parameters
With this parameter group, define the parameters of your vessel, the measuring medium
and the calculation of the measured signal. Signal-specific default settings such as the
failure signal or the upper current limit of the analog output signal are assigned to the
functions of the respective outputs (see Parameters 4.3 and 4.4).
4.2.1: Tank Geometry
4.2.1.1: Nozzle Height = Parameter 1.3
4.2.1.2: Tank Height = Parameter 1.4
4.2.1.3: Stilling Pipe? (F = no)
Stilling pipe available?
Value
By selecting yes or no, you specify whether the device is mounted on a stilling pipe. If you
select yes, Parameter 4.2.1.3.2 is enabled so you can specify the internal diameter of the
stilling pipe.
