4.1.3: Temperature Unit (F = °C)
Unit of the sensor temperature
Value
4.1.4: Other units (F = SI)
Units system for all other units
Value
With this function you 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, you can 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 the setting "yes" or "no" , you specify whether the device is mounted on a
stilling pipe. If you have selected "yes" , the Parameter 4.2.1.3.2 is enabled in which you can
specify the internal diameter of the stilling pipe.
