Fxsarasota_M - Spirit flow-x Function Reference

fxSarasota_M

The function calculates the density from a frequency input signal provided by a Sarasota densitometer
and corrects it for temperature and pressure effects in metric units.
Note: Calibration constants also need to be in metric units (°C, bar and kg/m3).
