Intro

For enhanced data collection, OFITE is pleased to introduce the new Model
1100 Pressurized Viscometer. This fully-automated system accurately deter-

mines the ow characteristics of fracturing uids and drilling uids in terms of

shear stress, shear rate, time, and temperature at pressure up to 2500 PSI.

Using the exclusive ORCADA® software, a computer novice can operate the
Model 1100, and yet the system is versatile enough for advanced research
and demanding test parameters. The rugged Model 1100 is suitable for both
eld and laboratory use. A waterproof case with wheels makes the unit com­pletely portable.

Setup

Computer

1. First, check that the computer’s AC power setting matches the available
power in your region. This switch is typically found on the upper back

panel of the computer and will be either 115V or 230V.

2. Connect the monitor, mouse, and keyboard to the computer and connect

the monitor and computer to an AC power outlet. The computer and
monitor were shipped with the appropriate power cords.

If your Model 1100 was supplied with a laptop computer instead of a

desktop model, simply open the laptop and turn the power on. The
AC power cord can be used to prevent the battery from draining
completely during operation. Remember to periodically charge the
battery by leaving the AC power cord plugged in overnight.

3. Turn the monitor and computer on. After the computer has booted up

completely, check for the ORCADA® icon on the desktop.

OFITE, 11302 Steeplecrest Dr., Houston, TX 77065 USA / Tel: [phone] / Fax: [phone] / www.ote.com 7

Setup

Viscometer

1. On the back panel, locate the three ¼" (6.35mm) NPT ttings. Connect
a water source (15 - 30 PSI / 104 - 208 kPa), Nitrogen source, and drain
hose to the appropriate ttings.

The Nitrogen is used to pressurize the sample and prevent boiling at

temperatures above 212°F (100°C). The water is used to raise and lower
the heater.

2. Screw the heater cable from the heat bath into the bottom of the cabinet.

3. Plug the thermocouple from the heat bath into the bottom of the cabinet.

4. Connect the viscometer to the computer using either a 9-pin RS232

cable, a Local Area Network connection with an Ethernet cable, or

Bluetooth.

5. Make sure the “Power” switch is in the off position. Plug the power cord

into an AC power source.

Setup

1. Turn the unit on. The power switch is located on the front panel.

System Test

2. If the heater is raised, lower it using the “Heater Lift/Lower” switch.

The sample cup is already attached to the viscometer in order to protect

the bob shaft during shipping. Always handle the bob shaft carefully;
bending it will result in poor viscosity readings.

3. To remove the sample cup, unscrew the sample cup nut and pull the
sample cup straight down.

4. Carefully apply a thin coating of high-temperature thread lubricant (#165­44-2) to the bob shaft threads.

5. To install the bob, slide it onto the bob shaft with the tapered end down
and screw it securely into place. An R1B1 bob/rotor combination is
standard for the Model 1100 Viscometer, however other combinations are
available. See page 5 for more information.

If either of these values does not display as expected, make sure the

Model 1100 is turned on and that all cables are securely connected. If the
problem is still not corrected, return to the “Main Screen” in the ORCADA®
software and choose “Edits” and then “Options”. In the “COM Port” drop­down menu, choose a different port and try again. See page 23 for
information about the “Options” screen.

8. It is recommended that a Calibration procedure be run due
to the possibility of mishandling during shipment. Refer to the
“Calibration” section on page 16 for detailed instructions on calibrating
the unit.

OFITE, 11302 Steeplecrest Dr., Houston, TX 77065 USA / Tel: [phone] / Fax: [phone] / www.ote.com 10

Setup

1. Install the bob as described in steps 1 - 6 on page 9.

Preparing for a Test

2. Fill the sample cup with the proper amount of uid based on the bob you

are using. Refer to the chart below.

Body Type B1 B2 B3 B4 B5 XB1 XB2 XB5
Sample Amount (mL) 42 78 96 104 52 32 73 44

3. Hold the sample cup by hand and position the bob in the center. Push the
sample cup up past the o-ring. Hold the sample cup in place and screw
the sample cup nut into place.

4. Position the heat bath under the sample cup and raise it. The bath can be
raised either manually and secured with the supplied pin or automatically
with the “Heater Lift / Lower” switch. Press the button to release.

Lock Pin

5. To pressurize the sample, gradually rotate the regulator knob clockwise.
To reduce pressure, gradually rotate the regulator knob counterclockwise

at a rate no greater than 60 PSI per minute.

Pressure is only necessary for tests temperatures above 200°F (95°C).

The heaters will be deactivated if the sample is not pressurized enough
to prevent boiling. The ORCADA® software will indicate this with a yellow
alarm light. The alarm light will turn green when the appropriate pressure
is applied to the sample. Refer to the chart below for the minimum
pressure requirements.

6. Once the pressure is set and the heater is in place, the Model 1100 is
ready to run a test.

OFITE, 11302 Steeplecrest Dr., Houston, TX 77065 USA / Tel: [phone] / Fax: [phone] / www.ote.com 12

Note: When running the “Mud” and “Cement” tests, the values for
“Dead Time” and “DAQ Time” on the Options screen should be ignored.
Temperature and pressure control, which are disabled during custom Auto­Mode tests, are available during a “Mud” or “Cement” test.

“Progress” - This button opens the Test Progress window, which shows all of
the steps of the current test and highlights the one currently in process.

“Status” - This box at the top of the screen shows the current status of the
test.

“Comm Timeout” - This light will be off when the PC is successfully
communicating with the viscometer. If communication is interrupted for any
reason, the light will shine red to indicate a problem.

“Start Logging” - This button is available in manual mode only. Click here to

begin recording test data. The light next to this button will shine green while
logging is in progress.

“Cond Pause” - This button will pause a test during the conditioning phase
and put the software into Manual Mode. While the test is paused, the motor
and heat controls can be controlled in the same manner as in a standard
Manual Mode test.

To resume the test, click the “Cond Pause” button again. You will be asked if

you want to “Continue” the test with the remaining conditioning time or if you
want to “Override” the remaining time and extend the effective conditioning
time. If you choose to “Continue”, the time remaining in the conditioning cycle
will appear as though the test was never paused. If you choose to “Override”,
the time remaining in the conditioning cycle will resume at the point where the
test was paused.

OFITE, 11302 Steeplecrest Dr., Houston, TX 77065 USA / Tel: [phone] / Fax: [phone] / www.ote.com 13

For example, assume a test has a conditioning time of 10 minutes and the

test is paused at the 5 minute mark for 1 minute. If the test is unpaused

using the “Continue” option, the time remaining in the conditioning cycle will
be 4 minutes. However, if the test is unpaused using the “Override” option,

the time remaining in the conditioning cycle will be ve minutes, making the

effective total conditioning time 11 minutes.

“Raw File Save Period” - This eld determines how often data is recorded

during a test.

“Experiment Name” - This eld will be used to identify the experiment later.
This eld is required before starting a test in Auto Mode or starting logging in

Manual Mode.

“Bob” - Select the type of bob currently being used in the unit. An incorrect

value in this eld will adversely affect your test results.

“Key” - The checkboxes next to the graph key enable and disable graphing

of the indicated values. For example, to exclude RPM from the graph,

uncheck the “RPM” box. You can also customize the appearance of the lines
on the graph by clicking on the line example on the right side of the key.

“Manual Mode Controls” - The manual mode controls, in the bottom left­hand corner of the screen, adjust the rotor speed and the temperature while
the unit is operating in manual mode.
