Proline Cubemass 300 Modbus RS485 Description of device parameters
Hauser 91
Factory setting Calc ref density
Additional information Selection
The Ref. dens API 53 option is suitable only for applications involving LPG
5)
, where the
flow rate is measured on the basis of the corrected volume flow.
Selecting this option means that the reference density is used, taking into account the
values in table 53 E of API MPMS section 11.2. Temperature measurement (measured
internally or read into the device from an external source→  87→  87) and density
measurement take place during operation while the medium is flowing. The mass flow is
divided by the reference density to give the corrected volume flow and is issued as an
output signal.
Ext. ref.density
Navigation  Expert → Sensor → Calculated value → Corr. vol.flow. → Ext. ref.density (6198)
Prerequisite In the Corr. vol.flow. parameter (→  90), the Ext. ref.density option is selected.
Description Displays the reference density which is read in externally, e.g. via the current input.
User interface Floating point number with sign
Additional information Dependency
The unit is taken from the Ref. dens. unit parameter (→  66)
Fix ref.density 
Navigation  Expert → Sensor → Calculated value → Corr. vol.flow. → Fix ref.density (1814)
Prerequisite The Fix ref.density option is selected in the Corr. vol.flow. parameter (→  90)
parameter.
Description Use this function to enter a fixed value for the reference density.
User entry Positive floating-point number
Factory setting 1 kg/Nl
Additional information Dependency
The unit is taken from the Ref. dens. unit parameter (→  66)
