Liquid Level Measurement, Part 2

SKU: ICLL200CEN
Duration: 1.00 Hr

This course will familiarize you with various devices and systems that use pressure to measure liquid level. Indirect level measurement instruments measure quantities, such as liquid pressure, that vary due to liquid level changes. Indirect level measurement instruments are a practical way to measure liquid levels, and the converted signals are used for indication and control functions throughout the plant.

Learning Objectives

Topic I: Pressure and Level Measurement

  • Define head pressure and use head pressure to compute the level of water in a tank.
  • Calculate the levels of liquids other than water.

Topic II: Level Measurement in Open Tanks

  • Describe how the following open tank systems measure liquid level: air trap, diaphragm box, bubbler system Describe how a bubbler system is typically maintained.

Topic III: Principles of Differential Pressure Elements

  • Define differential pressure.
  • Describe how the following differential pressure elements operate to reflect changes in liquid levels:
  • Simple diaphragm.
  • Diaphragm capsule.
  • Well-type manometer and float.
  • Bell-type manometer.

Topic IV: Using Differential Pressure for Level Measurement

  • Describe how differential pressure is used to measure level in the following situations:
  • Open tank.
  • Closed-tank, dry-leg.
  • Closed-tank, wet-leg.

Topic V: Temperature Compensation

  • Explain how changes in the temperature of a liquid in a tank affect its head pressure. Describe how a typical closed-tank, wet-leg system compensates for changes in the temperature of the liquid in the tank. Topic VI: Maintenance of Wet-leg Systems
  • Describe the following typical procedures involved in maintaining a DP device in a closed-tank, wet-leg system:
  • Isolating the device.
  • Blowdown. Venting.
  • Returning the device to service.
