Phase Dynamics Fiscal Skids are custom designed for Custody Transfer applications such as pipeline and tanker unloading facilities.  These are typically installed in a fast loop at the outlet of the processing facilities or pipeline storage.

The system integrates a Water-Cut Analyzer and a Coriolis flow meter to provide flow computer functions in terms of Total Oil and Total Water.  Customers have certified and approved this Analyzer for Custody Transfer applications.  API guidelines for the electronic water percentage measurement standard have been considered and followed.

Workmanship Standards

Workmanship and material standards include these items:

  • ASME Section IX
  • ASME B 31.3
  • EN 10204
  • NACE Standard MR0175-99

The Measurement Section is the portion of the Analyzer that contains the sensing elements where fluids are flowing at process conditions.  Process temperature capabilities are 0 to 204ºC.

The Electronics Enclosure Section contains the majority of the electronics with displays and user I/O.  Ambient temperature capability is -40ºC to +60ºC.

Measurement Section

The Measurement Section is typically 1, 2, or 3 inch 316/316L stainless steel with ANSI 150#, 300#, or 600# raised face flanges.  Process temperature is monitored with a built-in RTD sensor.

Electronics Enclosure Section

The Electronics Enclosure is available in explosion proof models made from either stainless steel or aluminum.

The display is a 6-inch color touchscreen with a data logging feature.  Graphing functions are provided to present trend data in an intuitive easily discernable format.  The enclosures provide for user interaction through a 4-button interface in addition to the touchscreen.

System power is supplied through either 100 to 240 Vac or 24 Vdc. Typical power dissipation is 18 Watts, maximum power dissipation is 33 Watts.

The data interface includes MODBUS, HART, analog I/O, pulse input, and alarm relays.

The Enhanced Electronics package option includes:

  • 4 x MODBUS RTU
  • 1 x HART (opt.)
  • 1 x 4-20mA input
  • 1 x 4-20mA output
  • 1 x pulse input
  • 2 x alarm relays, 1A / 125Vac

The Expanded Electronics package option includes:

  • 4 x MODBUS RTU
  • 1 x HART (opt.)
  • 5 x 4-20mA input
  • 5 x 4-20mA output
  • 3 x pulse input
  • 2 x alarm relays, 1A / 125Vac
