56 CI/FSV/FSS/430/450-EN Rev. G | VortexMaster FSV430, FSV450 SwirlMaster FSS430, FSS450
Media type Calculation method Description
Hot Water Calc. From T
The density is calculated in accordance with IAPWS-IF97 using the measured temperature value from
the internal temperature sensor.
If using an FSS430 / FSV430 without optional internal temperature sensor, a constant (parameter
"Preset Int.Temp") must be entered for the temperature. Alternatively, an external temperature
transmitter can also be connected with HART-communication.
Ext. Density
The hot water mass is calculated from the density.
The density can either be supplied via the analog input, the HART input, or as a constant (parameter
"Preset Density ").
NOTICE
Regardless of the media type and the calculation method, a density value is to be entered in the "Device Setup /
Plant/Customized / Compensation Setting / Preset Density " menu for the determination of the max. measuring range limits
The entered density will not be used for compensation purposes.
The entered density should be calculated in accordance with the typical (maximum) operating conditions.
