    HERMetic UTI Otex Visc Type:

     HERMetic UTImeter Otex The HERMetic UTImeter Otex is a portable liquid level
    gauge designed to be operated under open conditions on petroleum and
    chemical tanks where open gauging is permitted. The characteristics of the RTD
    are stored inside the sensor. The sensor is sending true temperature values to the
    electronic box. Therefore changing a sensor or a tape does not require a new
    calibration. The unit is used for custody transfer, inventory control measurement
    and free water detection on storage tanks. The HERMetic UTImeter Otex is set on
    the open gauging hatch. The unit enables 3, optionally 4 measurements in one
    single operation: • Ullage • Temperature • Oil-Water interface level • Innage,
    Reference height (Visc version).

    2. UTI D2401-2 ENCLOSED:-

     The triple function temperature, interface, and ullage sensor is powered by a


    single 9 volt battery contained within the hub assembly. Battery drain is
    extremely low, (Approximately 1-1/4 Mili-amperes in either the ullage, interface
    or the temperature mode), insuring very long operation, without battery
    replacement. Low battery warning is provided at the upper left corner of the
    temperature display LCD, when the battery voltage has dropped to a level that
    would, with further operation, cause excessive errors in temperature reading.

    TEMPERATURE MEASUREMENT PROCEDURE:


    1. If power is off, turn unit on by depressing “Off/On” push-button switch. Unit
    comes on Ullage/Interface mode. Depress “Mode” push-button switch to select
    temperature.

    2. If unit was on and in Ullage/Interface mode, simply press the “Mode” push-button to
    select temperature.

    3. Make sure “LO BAT” does not show at left upper corner of display. If “LO BAT” appears,
    replace battery even though the digital display turns on. The display may continue to operate even
    though the battery voltage is below normal. Temperature reading however, may be in error.

    4. Ground the assembly, release the turn handle reel lock. Lower the sensing sensor to the
    deepest reading desired. Make sure to exert restraining force while lowering.

    5. When the desired temperature ullage level is reached, allow the sensor to at this point for at
    least two (2) minutes. Then joggle the sensing sensor up and down, approximately 6” above and
    below the desired measurement level until the displayed temperature reading settles. Record this
    reading. For heavy crude oil products, the joggling procedure is a necessity to insure accurate
    readings. The viscous nature and low thermal conductivity properties of these petroleum products,
    makes the joggling procedure a necessity to insure accurate temperature in a minimum amount of
    time.

    6. Raise the sensor to the next ullage level to be measured. Repeat step 6.3.5. Continue
    raising sensor to all levels at which readings are desired.

    7. When the measurements are complete, push “Off/On” button to turn off and
    conserve battery power. Rewind the tape into the carriage reel assembly. Wipe the tape as
    it is rewound by placing the spring loaded wiper in the “On” position.

    8. Close the vapor valve, disconnect the valve securing cap, remove the gauging unit,
    disconnect the grounding cable. Replace the vapor valve cap.

    9. Lock the reel by rotation reel lock crank down, position. Follow the same final
    procedure as described in step above.
    3. HERMetic ENRAF UTI :-
