I've installed vortex flowmeter for steam flow with initial design of superheated 45kg/cm2 and 400c temp. However, the temp now dropped to 240 and pressure 37kg/cm2. I checked now that the steam is bo longer superheated, how should i adjust the setting in flowmeter? because the density is now jumping to 800 kg/m3

There's likely to be configuration settings for
- fluid > steam > saturated or superheat
- Density: setting for the density at reference operating pressure and temperature reference conditions.
- % water mass in saturated steam
- Density calc for saturated steam, saturated Temp; saturated Pressure
The device manual will have the configuration menu

The volumetric flow calculation for the dP generated by the now-current design pressure and temperature have to be re-run for the present orifice plate with its bore. The URV of the dP transmitter has to be changed to whatever the calc determines.
The conversion from volumetric flow to mass flow is done with absolute pressure and temperature measurements and calculation.
