For Model 2000 set up for Wet Gas Venturi machines type 2
1) Mass gas from Venturi no correction for wet gas +Mguc
2) Mass saturated gas from Venturi corrected for wet gas +MgS
3) Mass dry gas from Venturi corrected for wet gas +MD
4) Mass liquid corrected +ML
5) Mass two phase product including Water +MTP
6) Mass condensate liquid corrected +MC
7) Mass Water liquid corrected +MW
8) Mass Methanol liquid corrected +MM
9) Mass Hydro Carbon corrected +Mhc
10) Standard Volume of gas +VnG
11) Standard Volume of condensate +VnC
12) Standard Volume of Water +VnW
13) Energy +E
All the above Venturi Totals are also available in un-haltable versions
For Model 2000 set up for Coriolis meter machines
1)
Mass of Liquid in kg primary source. +Ml
2) Mass of Liquid in kg secondary source. +Mls
3) Volume of Liquid at Line conditions in m3 +VGl
4) Volume of Liquid at base conditions in m3 +VNl
5) Mass of Water in kg. +Mw
6) Volume of Water at Line conditions in m3 +VGw
7) Volume of Water at base conditions in m3 +VNw
8) Mass of Condensate in kg. +Mc
9) Volume of Condensate at Line conditions in m3 +VGc
10) Volume of Condensate at base conditions in m3 +VNc
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 Model 2000 types if enabled
1) Mass of CO2 +CO2
Each of the above totals (not the Un-haltable counters) is available for normal flows as listed and for Error (or Alarm) flows.
They are available for each a fitted stream and for the sum of the streams if available. If the Model 2000 is set-up to use a Bi-
directional Turbine meter or Ultrasonic meter input then all totals are also available in both forward (+) direction or reverse (-)
direction.
The pulse outputs for total flows are scaled using factors tof where each pulse equals the unit of tof. i.e. if tof is set to 100
each pulse equals 100 units.
The maximum frequency and duty cycle of the pulsed outputs can be pre-set as can the conducting or non conducting state
of the transistor output.
