diameters upstream and downstream from
flow disturbances with Conditioning Orifice
Plate Technology
• Improve accuracy and repeatability in small
line sizes with Integral Orifice Plate
Technology


Description:

Rosemount 2051CF Flowmeters combine the 2051 Pressure transmitter and the
latest primary element technology: Annubar Averaging Pitot Tube, Compact
Conditioning Orifice Plate and Integral Orifice Plate.

Better measurement begins by selecting the best flow technology for each application. Annubar® technology has been specified for over 35 years in applications requiring performance, flexibility, reliability and lower total cost of ownership. The innovative technology of the Annubar sensors offers more advantages that save time and money.
Features of the Rosemount Annubar Flowmeter include:

· Industry leading integrated DP Flowmeters

· Energy Savings gained through minimal permanent pressure loss

· Real-time mass and energy flow measurements available with integral temperature design

· Flo-tap design of the 485 and 585 allow installation without system shutdown

Applications:

Liquid, gas, and steam applications


Specifications:

4–20 mA HART (Output Code A)
Output
Two-wire 4–20 mA, user-selectable for linear or square root
output. Digital process variable superimposed on 4–20 mA
signal, available to any host that conforms to the HART
protocol.
2051
Digital communications based on HART Revision 5 protocol.
2051 with Selectable HART
The 2051 with Selectable HART comes with Selectable HART
Revisions. Digital communications based on HART Revision 5
(default) or Revision 7 (option code HR7) protocol can be
selected. The HART revision can be switched in the field using
any HART based configuration tool or the optional local
operator interface (LOI).

Span (option code D4) or Digital Zero Trim (option code DZ).
See 2051 with Selectable HART product manual
(00809-0100-4107) for LOI configuration menu.

Power Supply
External power supply required. Standard transmitter operates
on 10.5 to 42.4 Vdc with no load.
Turn-On Time
Performance within specifications less than 2.0 seconds after
power is applied to the transmitter.
Load Limitations
Maximum loop resistance is determined by the voltage level of
the external power supply, as described by:


Competitive Advantage:

· Industry leading integrated DP Flowmeters
