Set the "Unit" column to "m /h”
Through the look-up table, the density of saturated steam under the working condition of
3
0.75MPa is 4.400Kg / m . Then the mass flow Q = 360 * 4.400 = 1584 Kg / h.

Set the "Unit" column to “m /h”
Example 4: Electromagnetic flowmeter measures the volume flow of water
In the traffic configuration: the "Model" column is set to "Linear”
The column of "Coefficient K" is set to “1.000"
In the media configuration: ‘Media’ is set to ‘no compensation’
Set up:
Pressure sensor: two-wire 4-20mA pressure transmitter, range 0.00-1.00MPa
In the media configuration: ‘Media’ column is set to ‘Saturated Steam’
Set the "Compensation" column to "Pressure”
In the pressure configuration: the "Mode" column is set to "External Supplement”

0.75MPa (gauge pressure), scale flow 360 m /h
Set the "Unit" column to "Kg / h”
Set the ‘Range’ column to ‘0.00 ~ 25.00’
In the traffic configuration: the "Model" column is set to "Frequency Vortex”
‘Type’ column is set to ‘4-20mA’
In volume configuration: ‘Type’ column is set to ‘4 ～ 20mA’
Set the ‘Range’ column to ‘0.00 ~ 25.00’
Example 5: Vortex (frequency) flowmeter with pressure measurement of
saturated steam mass flow
Set up:
The column of "Coefficient" is set to "5000"
