"Slug Flow"
Programmed slug flow limits enable transmitter outputs and the ProLink
Status window to indicate conditions such as slug flow (gas slugs in a
liquid flow stream or liquid in a gas stream). Such conditions adversely
affect sensor performance by causing erratic vibration of the flow tubes,
which in turn causes the transmitter to produce inaccurate flow signals.
If the fluid density goes outside the user-defined slug flow limits, all of
the following occur:
• The Slug Flow indicator in the ProLink Status window switches ON.
• Milliamp outputs go to 0 mA if they produce a 0-20 mA current, or to
4 mA if they produce a 4-20 mA current.
• Frequency/pulse output goes to 0 Hz.
• Flow totalization stops while the density reading is outside density
limits.
• The diagnostic LED on RFT9739 field-mount, IFT9701, IFT9703,
and RFT9712 transmitters blink OFF once per second (75% ON,
25% OFF).
• The flowmeter resumes normal operation when liquid fills the flow
tubes (when density stabilizes within the programmed slug flow
limits).
Operational indicator Cause Corrective actions
Slug Flow • Gas slugs causing process density to
go below low slug flow limit
• Solids causing process density to go
above high slug flow limit
• Open View menu, choose Process Variables
to monitor density
• Open Configure menu, choose Characterize,
enter new slug flow limits
• Open Configure menu, choose Transmitter
Outputs, enter new slug duration for Model
RFT9739
Frequency Saturated • Flow rate driving RFT9739 output from
FREQ+ and RETURN terminals to 0 or
15 kHz
• Flow rate driving RFT9712 or RFT9729
frequency/pulse output to 0 or 11,520
Hz
• Open Configure menu, choose Transmitter
Variables, change flow measurement units
• Open Configure menu, choose Transmitter
Outputs, rescale frequency/pulse output
• Reduce flow rate
Frequency Output Saturated Flow rate driving IFT9701 or IFT9703
pulse output to 0 or 7200 Hz for versions
1.2 and higher, or 0 to 1200 Hz for lower
versions
Analog 1 Saturated • RFT9739 output from PV+ and PV–
terminals is 0, 2, or 22 mA
• RFT9712 or RFT9729 milliamp
output is 2 or 22 mA
• Open Configure menu, choose Transmitter
Outputs, change value of variable at 20 mA
• Alter fluid process
Analog 2 Saturated RFT9739 output from SV+ and SV–
terminals is 0, 2, or 22 mA
Analog Output Saturated IFT9701 or IFT9703 milliamp output is 0
or 22 mA
