Liquid Mass
3.3 Liquid Mass
Measurements:
Actual volume is measured by the flow element (DP transmitter, Flowmeter). Temperature
is measured by the temperature transmitter. A density transmitter can be used for direct
density measurements.
Calculations:
• The density and mass flow are calculated using the reference density and the thermal expansion coefficient of
the liquid (see "SET FLUID PROPERTIES" submenu)
Output Results:
• Display Results
Flow Rate, Resettable Total, Non-Resettable Total, Temperature, Density
• Analog Output
Rate, Total, Temperature or Density
• Pulse Output
Total
• Relay Outputs
Rate, Total or Temperature Alarms
Applications:
Monitoring mass flow and total of any liquid. Flow alarms are provided via relays and datalogging is available
via analog (4-20mA) and serial outputs.
