  • Page 5: General Information

    PREFACE General Information Description The Chandler Engineering Inline (Flow-Thru) Viscometer is a low pressure couette (cup/bob) viscometer for real time measurement of oilfield fluids during treatments. The instrument is connected in a sample line from the clean fluid delivery line. The viscometer measures viscosity at the standard 511 sec using the API standard R1 rotor, B1 bob, and F1 spring.

    PREFACE Specifications Pressure Range: 100 PSIG 32°F – 160°F Temperature Range: Flowrate: 1-5 gpm Viscosity Range: 0-160 cP Input Voltage: 12VDC Power: 6 A @ 12VDC 13.5” x 17” x 20” Dimensions: Net Weight: 56 lbs. (36 kg) Operating Speed: 300 RPM (511 sec ½”...
  • Page 7: Safety Requirements

    PREFACE Safety Requirements READ BEFORE ATTEMPTING OPERATION OF INSTRUMENT The Chandler Engineering Flow-Thru Viscometer is designed for operator safety. However, the instrument should be handled by personnel that have the appropriate safety training. To ensure safety: • Use appropriate Personal Protective Equipment such as safety glasses, latex gloves, etc. •...

    SECTION 1 – INSTALLATION Section 1 – Installation Unpacking the Instrument Remove the instrument from the packing crate carefully. The unit comes fully equipped with all the necessary components and ordered spare parts. Make sure that no parts are lost when discarding the packing materials.
  • Page 10: Instrument Preparation

    SECTION 1 – INSTALLATION Instrument Preparation 1. The viscometer is configured for portable or permanent installation. 2. The electronics enclosure is provided with 6 feet of instrument cable for remote mounting the operator interface in a more convenient location. 3. The instrument is provided with 2, ½” NPT threads for fluid connections. Connect the fluid delivery line from a clean fluid pressure source (such as the clean side blender centrifugal) to the lower viscometer port (or the filter system if equipped).
  • Page 11: Section 2 - Operating Instructions

    SECTION 2 – OPERATING INSTRUCTIONS Section 2 – Operating Instructions Test Preparation 1. Locate the Instrument on a level surface and make all fluid and power connections. 2. Turn the instrument ON (Green LED will be on). Note: Turning ON the instrument power will automatically zero the encoder. Therefore, the fluid input valve should be closed and no fluid should be flowing through the instrument.
  • Page 12 SECTION 2 – OPERATING INSTRUCTIONS 5. Carefully wipe dry the inside of the viscometer and the bob. 6. Reinstall measurement head onto viscometer.
  • Page 13: Section 3 - Maintenance

    SECTION 3 – MAINTENANCE Section 3 - Maintenance Cleaning 1. Drain all fluid from the viscometer. 2. For good measurement practice, the viscometer should be hand cleaned periodically to remove fluid contamination. First, disconnect the encoder cable and unthread the large coupling nut to remove the measurement head.
  • Page 14 SECTION 3 – MAINTENANCE 5. Unthread the retaining nut and pull bob assembly out of measurement head. The bob assembly is held magnetically. Caution: Do not place the bob assembly near magnetic materials because of the strong magnets. 6. Clean and wipe any residue from the bob assembly. Be careful not to scratch the bob or shaft as this will cause measurement error.
  • Page 15: Calibration

    SECTION 3 – MAINTENANCE 9. After cleaning rotor assembly, reinstall into viscometer using threaded nut. 10. Reinstall measurement head onto viscometer and connect encoder cable. Calibration Checking Calibration 1. Calibration should be checked prior to every use with a known clean calibration fluid, preferably, use a 100cP calibration oil.
  • Page 16 SECTION 3 – MAINTENANCE 9. Loosen the set screws holding the spring mandrel. 10. Turn the mandrel clockwise to decrease viscosity and counterclockwise to increase viscosity. 11. Tighten set screws (Note the spring assembly may need to be turned counterclockwise by hand to position the encoder against the zero stop prior to tightening.
  • Page 17: Torsion Spring Assembly

    SECTION 3 – MAINTENANCE Torsion Spring Assembly The Flow-Thru Viscometer uses a standard F1 spring assembly. Replacement of Spring Assembly 1. Unthread top cap and loosen set screws at the top of the brass spring clamp. 2. Remove screws from spring housing and remove spring housing. 3.
  • Page 18: Encoder Assembly

    SECTION 3 – MAINTENANCE Encoder Assembly Replacement of the Encoder/Bearings 1. Remove screws at the top of the measurement head. Carefully, remove the encoder/spring assembly from the measurement head. The encoder/spring assembly is sealed with an O-ring. 2. With the encoder mechanism exposed, the assembly must be handled carefully to avoid damage to the components.
  • Page 19 SECTION 3 – MAINTENANCE 4. Unthread top cap and loosen set screws at top of spring assembly. 5. Remove screws from spring housing and remove spring housing. 6. Loosen set screws along the bottom of the spring holder and remove from shaft. 7.
  • Page 20 SECTION 3 – MAINTENANCE 9. The encoder can be removed from the mag drive shaft by loosening the 2 screws. 10. Reassemble and recalibrate.
  • Page 21: Rotor Assembly

    SECTION 3 – MAINTENANCE Rotor Assembly Replacement of Rotor Seal/Bearings 1. First unthread the large coupling nut for the motor. 2. Remove two screws which attach the rotor to the shaft. 3. Remove screws holder motor flange to the bearing housing.
  • Page 22 SECTION 3 – MAINTENANCE 3-10 4. Unthread bearing retainer and remove shaft and bearing assembly. Remove shaft seal. 5. Inspect bearings and seal and replace, if required. Reassemble.
  • Page 23: Bob Assembly

    SECTION 3 – MAINTENANCE 3-11 Bob Assembly Replacement of Bob Shaft Bearings 1. The bob shaft runs in two glass journal bearings. One is located at each end of the bob shaft. Carefully remove the measurement head. Note: The measurement head has an O-ring seal and will be tight during removal. 2.
  • Page 24: Maintenance Schedule

    SECTION 3 – MAINTENANCE 3-12 6. Remove screws at the top of the measurement head. Carefully, remove the encoder/spring assembly from the measurement head. The encoder/spring assembly is sealed with an O-ring. 7. Remove the threaded retaining nut in the top of the measurement head housing. 8.
