For Coriolis meter machines
+Ml Mass of Liquid in kg primary flow source.
+Mls Mass of Liquid in kg secondary flow source.
+VGl Volume of Liquid at Line conditions in m3
+VNl Volume of Liquid at base conditions in m3
+Mw Mass of Water in kg.
+VGw Volume of Water at Line conditions in m3
+VNw Volume of Water at base conditions in m3
+Mc Mass of Condensate in kg.
+VGc Volume of Condensate at Line conditions in m3
+VNc Volume of Condensate at base conditions in m3
All the above Coriolis Totals are also available in un-haltable versions
Primary and secondary source from the Coriolis meter can be either serial data via Modbus communication or pulse
accumulation via pulse input.
For All machine types if enabled
+CO2 Mass of CO2
Which are then sub-divided into groups as follows:-
•
Main Totals
•
Alarm Totals
•
Main Totals when HOLD function last operated
•
Alarm Totals when HOLD function last operated
•
Current 15 min, Hour, Day and Month non-accumulated Totals
•
Previous 15 min, Hour, Day and Month non-accumulated Totals
•
Last Day non-accumulated Totals
•
Previous Hour, Day and Month accumulated Totals
•
Previous Hour, Day and Month accumulated Alarm Totals
•
Current Hour, Day and Month non-accumulated Alarm Totals
•
Previous Hour, Day and Month non-accumulated Alarm Totals
•
Last Day and non-accumulated Alarm Totals
The items will be divided into pages with a maximum of four items per page, each item will be displayed with the
corresponding symbols, scaling factors and units.
2.2.7. MAIN MENU FUNCTION Line Conditions
This menu item is a read only display and when selected will show all the pages of line conditions available in this machine
these will include:-
General sub-menu items, i.e. items that relate to the machine and not specifically to streams.
Digital Input Status The Status inputs appear as Digital i/p X.Y on the M2000 display
Where
X is the input number 1, 2 or 3
Y is the USER Board Slot number 1, 2, 3, 4 or 5.
Stream N sub-menu items, i.e. items that relate to the streams
Flow Rates
Peak Flow rates and Time and Date of occurrence
Line Pressure and Temperature and status
Line and Base Compressibility
Line Density
Correction Factors
Meter Information
Station sub-menu items, i.e. items that relate to station functions only in a Multistream machine.
Station Flow rates
The items will be divided into pages with a maximum of four items per page, each item will be displayed with the
corresponding symbols, scaling factors and units.
