Installation:
Mounting
! Using the 2 pipe clamps (supplied) mount on a 2” vertical or horizontal
pipe.
! Or use lag screws (not supplied) to mount to wall.
Supply or Signal Connection (on the left side of the Manifold Assembly)
! For the Multi-Stroke models connect a clean instrument supply of 5 to
20 psi to the 1/8" NPT port on the Accumulator’s manifold marked “C”
or “Control”. (Supply may also come from the level controllers output)
! For the Single-Stroke models connect the “C” or “Control Signal” port to
the separator level controller’s output.
Process or Sample In Connection (on the right side of the Manifold
Assembly)
! For both models tube your connection for the process to be sampled to
the 1/8" NPT port on the Accumulator marked “S” or “Sample In”.

SWI-015 SA-77 Manual-2.docPage 4 of 24 Rev: 0.
Sample Probe Installation (Industry Best Practice Sharing)
! Probe weld-o-lets should be placed on the side of the pipe at center, so
the probe quill sits in the horizontal plane.
! If the choice is available mount in vertical piping flowing upwards.
! Always pull the sample from between the associated meter and the
level control valve.
! Mount Sampler as close as possible to sample point, keeping sample
tubing as level and short as possible.
! Install a low cracking pressure check valve in the sample line at the
probe block valve. When the sample line has a slope in it this check valve
will prevents sample stratification which allows oil or water to rise or fall
back into the dump/meter leg causing an error in water cut value.
! Use full port valves in the sample line, not restrictive needle valves.
! Use !” tubing to keep sample line volume low.
Bore through and custom probes are also available.

Operation:
Run / Stop (See General Overview Drawing this page- Control Valve)
! To start the Accumulator push the knob in. To stop the Accumulator
pull the knob out. Note: when the Accumulator’s jar is full, pressure from
the sample line will push this knob out and stop the Accumulator.
Sample Size Adjustment (See General Overview Drawing on this page)
! The Accumulator can be adjusted to change the size of sample taken
in each stroke. To increase the size of the sample per cycle, adjust the
Sizer Assembly out.
Cycle Time Adjustment - Multi-Stroke Series Only (See drawing & parts
reference on page 10; item 2)
! To adjust the time period of the Accumulator’s cycle use the metering
valve that feeds supply pressure to the volume bottle and the oscillating
relay. Opening this valve will speed up (shorten) the cycle time.
Bottle Shut-off Adjustment (See drawing & parts reference on page 9;
items 5, 8 & 9)
! Loosen Lock Nut (item 8) and adjust the Valve Stem (item 9) in relation
to Cage Housing (item 5) until proper shut-off occurs. The more stem
sticking out past the lock nut the less sample required to shut off the
assembly.

Water-Cut (BS&W) Procedure
Obtaining accurate water-cut (BS&W) percentage during well
proration testing is an important aspect of oil well
measurement and accounting because it directly affects the
oil volume determination. However, it is one that is frequently
overlooked. In some cases, well test liquids are easily
separated using standard procedures, such as adding a
small amount of demulsifier and spinning the sample in a
centrifuge, as discussed later in this section. Other situations
(such as very high water cuts or tight emulsions) require
additional effort to achieve accurate results. Due to varying
BS&W ranges, water-cut procedures have been divided into
three categories, which are described on the following pages.
Note that these procedures are not considered enforceable
EUB (ERCB) regulations but are recommended for well test
applications in their own Audit Handbook Directive 46.
For further reference, BS&W determination is discussed in
more detail in the API MPMS, Chapter 10, Section 4:
Determination of Sediment and Water in Crude Oil by the
Centrifuge Method (Field Procedure).
See the following pages for each of the three
procedures:
• For 0% to 10% BS&W
• For 10% to 80% BS&W
• For 80% to 100% BS&W

Water-Cut (BS&W) Procedures (cont.)
For 0% to 10% BS&W
1. Obtain a representative sample of liquid (minimum 500 ml). Sample
should be taken as close to the test meter as possible.
2. Shake the sample inside the container vigorously to ensure a good
mix prior to pouring into centrifuge tubes.
3. Fill each of two centrifuge tubes with the sample; to the 50 ml mark in
100 ml tubes or to the 100 ml mark in 200 ml tubes (read the top of the
meniscus)
4. Add solvent (toluene, varsol, etc.) to bring the level in the tubes to 100
ml or 200 ml respectively (solvent should be water saturated at 60°C).
5. Add demulsifier as required. Stopper the tubes and shake vigorously
to ensure a good mix. Heat the samples to 60°C or treater operating
temperature before spinning.
6. Place the sample tubes in the centrifuge on opposite sides to create a
balanced condition. Spin for at least 5 minutes.
7. Compare the results from each tube. If the two results are not the
same, return the tubes to the centrifuge and spin again for at least 5
minutes (do not shake the tubes at this stage). Repeat this operation, and
if the samples still do not match after two more spins, discard this sample
and take another one.
8. Read & record the volume of water and sediment in the bottom of
each tube.
a. For 100 ml tubes, read to the nearest 0.05 ml from the 0 to 1 ml
graduations and to the nearest 0.1 ml above the 1 ml graduation mark.
b. For 200 ml tubes, read to the nearest 0.05 ml from the 0 to 3 ml
graduations, to the nearest 0.25 ml between the 3 and 5 ml graduations,
and to the nearest 0.5 ml above the 5 ml graduation mark.
9. For 100 ml tubes, water cut is determined by adding the results of both
tubes together.!
!
10. When using 200 ml tubes, water cut is determined by reading the
results directly from one tube.!

Water-Cut (BS&W) Procedures (cont.)
For 10% to 80% BS&W
1. Obtain the maximum representative sample of liquid feasible (between 800
and 1000 ml).
2. Transfer the entire sample into an adequately sized graduated cylinder.
(Mason jars will not provide adequate results.)
3. Place the graduated cylinder into a heat bath at approximately 60°C (or as
close to treater temperature as possible) until the sample temperature and
free water fallout have stabilized. A clear oil/water interface should be visible.
4. Read and record the total volume, volume of free water, and volume of oil in
the graduated cylinder.
a. Calculate the free water percentage as follows:
Percentage of free water =
Volume of free water / Total volume x 100%
5. Using a burette filler, draw 100 ml from the oil portion in the graduated
cylinder and fill each of two centrifuge tubes exactly to the 50 ml mark. Add
heated solvent to bring the level in the tubes to exactly the 100 ml mark. Add
demulsifier as required.
6. Follow the procedure outlined for spinning samples of 0% to 10% water cut.
7. Once the centrifuge has stopped, read and record the volume of water and
sediment in the bottom of each tube. The combined results will be the water
cut of the emulsion.
a. Calculate the percentage of water remaining as follows:
Percentage of water remaining =
Total oil volume in cylinder x Water cut of oil / Total volume
Calculate the total water-cut percentage as follows:
Total water-cut percentage =
Percentage of free water + Percentage of water Remaining

Water-Cut (BS&W) Procedures (cont.)
For 80% to 100% BS&W
1. Obtain the maximum representative sample of liquid feasible (between 800
and 1000 ml).
2. Transfer the entire sample into an adequately sized graduated cylinder.
(Mason jars will not provide adequate results.) For very high water-cut wells,
it may be necessary to wash out the inside of the sample container with a
measured volume of solvent to ensure that all of the oil is removed. If this is
done, it is necessary to account for the additional amount of solvent added
when calculating water cut.
3. Place the graduated cylinder into a heat bath at approximately 60°C (or as
close to treater temperature as possible) until the sample temperature and
free water fallout have stabilized. A clear oil/water interface should be visible.
4. Read and record the total volume and volume of free water in the graduated
cylinder.
Calculate the water-cut percentage as follows:
Water-cut percentage =
Volume of free water / Total volume x 100%
If solvent is added to the sample at any stage of this procedure, it must be
accounted for in the calculation as follows:
Water-cut percentage =
Volume of free water / (Total volume-Volume of solvent)x 100%
The oil portion of the samples does not have to be spun due to the
limited amount of the oil portion of the sample available.
