Flow Measurement in Pipes and Ducts

Flow Measurement in Pipes and Ducts
Note: This PDH course is a recorded video presentation.
Course Highlights

This online engineering PDH video presentation focuses on the measurement of the flow rate of a fluid flowing under pressure in a closed conduit. It discusses the several categories of pipe flow measurement devices along with some associated example calculations for differential pressure flow meters and pitot tubes. It addresses the general principles of operation for each type of flow meter and general advantages and disadvantages of each.


Measurement of the flow rate of a fluid flowing under pressure (closed conduit) is carried out for a variety of purposes, such as billing for water supply to homes or businesses, or for monitoring or process control of a wide variety of industrial processes that involve flowing fluids. The closed conduit is often circular, but also may be square or rectangular (such as a heating duct) or any other shape.


This 3 PDH online video presentation is intended primarily for mechanical, civil, environmental, chemical, mechanical, and industrial engineers, who are interested in learning more about flow measurement in a closed conduit.

Learning Objectives

This PE continuing education video presentation is intended to provide you with the following specific knowledge and skills:

  • Calculating the flow rate from measured pressure difference, fluid properties, and meter parameters, using the equations for venturi, orifice and flow nozzle meters
  • Determining which type of ISO standard pressure tap locations are being used for a given orifice meter
  • Calculating the orifice coefficient, Co, for specified orifice and pipe diameters, pressure tap locations and fluid properties
  • Estimating the density of a specified gas at specified temperature and pressure using the Ideal Gas Equation
  • Calculating the velocity of a fluid for given pitot tube reading and fluid density.
  • Knowing the general configuration and principle of operation of rotameters and positive displacement, electromagnetic, target, turbine, vortex and ultrasonic meters
  • Knowing the recommended applications for each of the types of flow meters
  • Familiarizing with the general characteristics of the types of flow meters
