Roxar SandLog
High Accuracy Sand/Erosion Monitoring
The effective management of sand is important for the integrity
of oil and gas assets and for optimizing production.
Together with Emerson’s unique multiple element sand/erosion
probe and Roxar Fieldwatch software, Roxar SandLog provides
probably the best combination of detection reliability and
accuracy for sand/erosion monitoring.
For optimized sand monitoring, it is suggested to combine
in-line sand/erosion probes with non-acoustic sand detectors
(SAM, see separate data sheet).

•
Covering more of the pipe diameter, enhanced ability to
detect sand particles in the flow
Redundancy of elements
Can also read combined sand/erosion/corrosion probes
Configuration flexibility
Roxar SandLog is available with a range of communication
options:
•
•
•
•
•
SandLog Terminal (Continuous off-line data logging, data
retrieval through field terminal)
SandLog Field Bus (Digital data through Roxar Field Bus)
SandLog 4-20 mA (Analog)
SandLog 4-20 - Terminal (combined)
SandLog Wireless is also available with WirelessHART®
communication (see separate data sheet)
Observe that sand production, and thus erosion rates, may
change rapidly. Therefore, digital, on-line configuration is
recommended for permanent sand/erosion monitoring.

Measurement Principles
Sand/erosion is measured through the erosive effect caused by
sand particles hitting the sensing elements of the in-line sand/
erosion probe, using Electrical Resistance (ER) technology.
When combining measured sand/erosion rates with flow
rates and assumed sand particle size, sand production can be
quantified.
•
It is suggested to combine intrusive sand/erosion
monitoring with acoustic, non-intrusive sand monitors
for optimized sand and sand/erosion monitoring in one
integrated system.
Roxar SandLog Configuration Options
For all SandLog options, in-line probes are connected to
SandLog through a probe cable (max length 20 m). A probe
connection housing is used for connecting probe leads to the
probe cable.
SandLog Terminala (Off-line).
In this version, a battery powered SandLog instrument is set up
to monitor the probe continuously (measurement interfals from
every 2 minutes to every 24 hours). Data is stored in SandLog,
and retrieved by the use of a portable terminal.
SandLog Terminal is powered with commonly available AAA
alkaline batteries.
SandLog Terminal can be upgraded to SandLog Field Bus by
changing the instrument’s interface card.
SandLog Field Bus (On-line).
Sudden increase in sand production detected by multiple
element sand/erosion probe, SandLog and Fieldwatch software
The Roxar sand/erosion probes are designed according to the
fact that it is difficult to predict sand distribution in a line, as it
depends with flow velocities and flowline design, which is the
basis for the following unique recommendations/solutions:
•
•
•
•
It is recommended that sand/erosion probe is installed
in vertical pipe, preferably 10 pipe diameters after a
bend, where sand is assumed to be relatively uniformly
distributed within the pipe. Sand/erosion probes may
also be installed in other positions, e.g. horizontal lines,
depending on flow conditions.
Sand/erosion probe is installed into the pipe, with sensing
elements facing the flow at an optimum angle, in order to
maximize sensitivity and minimize response time for sand
erosion and performance.
Multiple elements (max 4) increase probability to detect
sand independently on distribution within the pipe, and
also give redundancy with respect to probe measurements
and performance.
Probes with a combination of corrosion elements and sand/
erosion elements can also be monitored by Roxar SandLog.
www.EmersonProcess.com/Roxar
For on-line, digital communication, SandLog instruments are
powered and communicate through cable via a Field Interface
Unit (FIU)b. The FIU needs to be installed in safe area (could
be an explosion proof enclosure). Each FIU can handle up to
8 SandLog instruments (2 cable loops, maximum 4 SandLog
instruments per cable loop). Observe that CorrLog and SandLog
instruments can be combined in the same cable loops.
The FIU communicates with PC/Fieldwatch softwarec through
a variety of options (RS 232, RS 485, LAN, telephone modems,
etc).
In this version, SandLog instrument does not contain batteries,
and the instrument can be considered maintenance free.
SandLog Field Busd requires Fieldwatch software for operation
and data management.
SandLog 4-20 mA.
SandLog is also available with communication over an analog 4
- 20 mA communication loop. From the measurements, metal
loss is calculated in the instrument, and converted to a signal
between 4 - 20 mA. The signal is converted back to metal loss.
Observe that for multiple element probes, average metal loss
for all elements only is transmitted.
SandLog 4 -2 0 mAe provides data directly to the receiver
without the use of Fieldwatch instrument.

The SandLog 4 - 20 mA is powered via the 4 - 20 mA cable loop.
Observe that a barrier is required on the 4 - 20 mA cable loop to
maintain intrinsically safe certification.
SandLog 4 - 20 mA/Terminal
This version combines the 4 - 20 mA communication with the
option of downloading digital data to a terminal for data analysis
and reporting.
In this case, SandLog is powered via AAA alkaline batteries.
