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:

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.
