3.3 Liquid Mass

Measurements:

Actual volume is measured by the flow element. Temperature is measured

by the temperature transmitter. A density transmitter can be used for

direct density measurements or a pressure transmitter may be utilized.

Calculations:

• The density and mass flow are measured directly or calculated using

the reference density and the thermal expansion coefficient of the liquid

(see "SET FLUID PROPERTIES" submenu)

Output Results:

• Display Results

Mass Flow Rate, Resettable Total, Non-Resettable Total,

Temperature, Density or Pressure

• Analog Output

Mass Rate, Total, Temperature or Density or Pressure

• Pulse Output

Mass Total (corrected or uncorrected)

• Relay Outputs

Mass Flow Rate, Total, Temperature, Pressure or Density 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.
