  2. Level sensor - Wikipedia

    en.wikipedia.org/wiki/Level_sensor

    The technique is inherently self-cleaning. It is highly recommended for liquid level measurement applications where ultrasonic, float or microwave techniques have proved undependable. The system will require constant supply of air during measurement. The end of the tube should be above certain height to avoid sludge from clogging the tube.

  3. DP cell - Wikipedia

    en.wikipedia.org/wiki/Dp_cell

    The DP-cell will indicate the relative difference between the pressure of the vessel (container) and the atmospheric pressure. This signal is often wired to an indicator that reads out locally, or remotely in a control room, and/or as a control (or feedback) signal to a valve, pump, or other control element to maintain a set pressure, or limit ...

  4. List of abbreviations in oil and gas exploration and production

    en.wikipedia.org/wiki/List_of_abbreviations_in...

    MDSS – measured depth referenced to mean sea level zero datum – "subsea" level MDT – modular formation dynamic tester, a tool used to get formation pressure in the hole (not borehole pressure which the PWD does).

  5. Robot calibration - Wikipedia

    en.wikipedia.org/wiki/Robot_calibration

    Often Level-1 and Level-2 calibration are sufficient for most practical needs. [1] [2] Parametric robot calibration is the process of determining the actual values of kinematic and dynamic parameters of an industrial robot (IR). Kinematic parameters describe the relative position and orientation of links and joints in the robot while the ...

  6. Calibration - Wikipedia

    en.wikipedia.org/wiki/Calibration

    This is called a limited calibration. But if the final measurement requires 10% accuracy, then the 3% gauge never can be better than 3.3:1. Then perhaps adjusting the calibration tolerance for the gauge would be a better solution. If the calibration is performed at 100 units, the 1% standard would actually be anywhere between 99 and 101 units.

  7. Precision measurement equipment laboratory - Wikipedia

    en.wikipedia.org/wiki/Precision_Measurement...

    A Precision Measurement Equipment Laboratory (PMEL) is a United States Air Force (USAF) facility in which the calibration and repair of test equipment takes place. This practice is also known as metrology: the science of measurement. Metrology is defined as the science of weights & measures, while a PMEL is the place where technicians perform ...

  8. Flow measurement - Wikipedia

    en.wikipedia.org/wiki/Flow_measurement

    Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters with industrial applications are listed below: Obstruction type (differential pressure or variable area) Inferential (turbine type) Electromagnetic

  9. Dynamic carrier control - Wikipedia

    en.wikipedia.org/wiki/Dynamic_carrier_control

    Dynamic carrier control (DCC) is a method of reducing power consumption in radio transmitters during periods of low audio activity or silence. It is a type of Modulation-Dependent Carrier Level control, or MDCL. All modern high-power (>50 kW) shortwave radio transmitters incorporate DCC of some kind, as well as some mediumwave (MW) transmitters.
