Flow measurement is the process of measuring the quantity or rate of a fluid (liquid or gas) that moves through a pipe or a channel. Flow measurement is important for many reasons, such as:



  • Monitoring and controlling processes in various industries, such as oil and gas, water, power, chemical, pharmaceutical, food and beverage, etc.



  • Ensuring product quality, safety, efficiency, performance, compliance, etc.



  • Billing customers or suppliers based on the amount or volume of fluid delivered or consumed.



  • Optimizing energy consumption or conservation.



  • Detecting leaks or anomalies in pipelines or networks.



  • Conducting research and development in fluid dynamics, thermodynamics, hydrology, etc.



Flow measurement is done by using devices called flow meters, which are instruments that measure the flow of a fluid. There are many types and classifications of flow meters, depending on various criteria, such as:



  • The principle or technique that they use to measure flow, such as differential pressure, positive displacement, turbine, vortex, electromagnetic, ultrasonic, Coriolis, thermal, etc.



  • The design or configuration of the flow meter, such as orifice plate, venturi tube, nozzle, rotameter, oval gear, turbine wheel, propeller, vortex shedding, magnetic coil, ultrasonic transducer, Coriolis tube, thermal sensor, etc.



  • The fluid properties that they measure or rely on, such as density, viscosity, conductivity, temperature, pressure, etc.



  • The installation or mounting method of the flow meter, such as inline, insertion, clamp-on, etc.



  • The output or signal that they produce or transmit, such as analog or digital, pulse or frequency, voltage or current, etc.



Flow measurement accuracy and reliability depend on many factors, such as:



  • The selection and sizing of the flow meter for a given application and fluid.



  • The installation and calibration of the flow meter according to the manufacturer's specifications and recommendations.



  • The maintenance and verification of the flow meter's performance and condition over time.



  • The correction and compensation of the flow meter's readings for any errors or uncertainties caused by environmental or operational conditions.



  • The validation and analysis of the flow meter's data for any anomalies or outliers.



Flow Measurement Applications




Flow measurement is used in a wide range of industries and sectors that deal with fluids in various forms and states. Some of the most common ones are:



  • Oil and gas: Flow measurement is essential for the exploration, production, transportation, refining, distribution, and consumption of oil and gas products. Flow measurement is used to monitor and control the flow of crude oil, natural gas, liquefied petroleum gas (LPG), liquefied natural gas (LNG), refined products (such as gasoline, diesel, jet fuel), etc. Flow measurement is also used to measure the volume and composition of oil and gas reserves and resources.



  • Water: Flow measurement is vital for the management and conservation of water resources. Flow measurement is used to measure the flow of water in rivers, lakes, reservoirs, aquifers, wells, canals, irrigation systems, etc. Flow measurement is also used to measure the supply and demand of water for domestic, industrial, agricultural, and environmental purposes. Flow measurement is also used to detect and prevent water losses, leaks, or thefts.



  • Power: Flow measurement is crucial for the generation, transmission, distribution, and consumption of electricity. Flow measurement is used to measure the flow of steam, water, air, gas, or other fluids that are used to drive turbines, generators, boilers, cooling towers, heat exchangers, etc. Flow measurement is also used to measure the flow of fuels (such as coal, oil, gas, biomass, etc.) that are used to produce electricity. Flow measurement is also used to measure the flow of electricity itself through wires, cables, transformers, switches, meters, etc.



  • Chemical: Flow measurement is important for the synthesis, processing, transportation, storage, and utilization of chemical substances. Flow measurement is used to measure the flow of raw materials (such as oil, gas, water, air, etc.) that are used to produce chemical products (such as plastics, rubber, fertilizers, pharmaceuticals, cosmetics, etc.). Flow measurement is also used to measure the flow of intermediate and final products that are sold or consumed by customers or end-users. Flow measurement is also used to measure the flow of waste or by-products that are generated or disposed of by chemical processes.



  • Food and beverage: Flow measurement is important for the preparation, processing, packaging, transportation, storage, and consumption of food and beverage products. Flow measurement is used to measure the flow of ingredients (such as water, milk, juice, oil, sugar, flour, etc.) that are used to make food and beverage products (such as bread, cheese, yogurt, beer, wine, soda, etc.). Flow measurement is also used to measure the flow of finished products that are sold or consumed by customers or end-users. Flow measurement is also used to measure the flow of waste or by-products that are generated or disposed of by food and beverage processes.



Flow Measurement Techniques and Methods




As we mentioned earlier, there are many techniques and methods for measuring flow, each with its own advantages and disadvantages. In this section, we will give you an overview of some of the most common and widely used techniques and methods for measuring flow, and their pros and cons. We will also provide some criteria and guidelines for selecting the best technique and method for a given situation.


The main techniques and methods for measuring flow can be broadly classified into two categories: direct and indirect. Direct techniques and methods measure the flow directly by counting or capturing the fluid particles or units that pass through a given cross-section or volume. Indirect techniques and methods measure the flow indirectly by measuring a property or phenomenon that is proportional or related to the flow, such as pressure, velocity, force, frequency, etc.


Some examples of direct techniques and methods are:



  • Positive displacement: This technique uses a device that divides the fluid into discrete units or volumes and counts them as they pass through. The flow rate is calculated by multiplying the number of units or volumes by their size. Some examples of positive displacement devices are oval gear, piston, diaphragm, nutating disc, rotary vane, etc.



  • Mass flow: This technique uses a device that measures the mass of the fluid that passes through per unit time. The flow rate is calculated by dividing the mass by the density of the fluid. Some examples of mass flow devices are Coriolis, thermal, etc.



Some examples of indirect techniques and methods are:



  • Differential pressure: This technique uses a device that creates a constriction or obstruction in the flow path, such as an orifice plate, a venturi tube, a nozzle, etc. The device causes a pressure drop across the constriction or obstruction, which is proportional to the square of the flow rate. The flow rate is calculated by applying Bernoulli's equation or other empirical formulas.



  • Turbine: This technique uses a device that has a rotating element, such as a wheel, a propeller, a fan, etc. The device is placed in the flow path and rotates at a speed that is proportional to the flow velocity. The flow rate is calculated by multiplying the rotational speed by a calibration factor.



  • Vortex: This technique uses a device that has a bluff body, such as a cylinder, a wedge, a diamond, etc. The device is placed in the flow path and creates vortices or swirls behind it. The vortices alternate from one side to another at a frequency that is proportional to the flow velocity. The flow rate is calculated by multiplying the frequency by a calibration factor.



  • Electromagnetic: This technique uses a device that has a magnetic coil and electrodes. The device creates a magnetic field across the flow path and measures the voltage induced by the fluid as it passes through. The voltage is proportional to the product of the flow velocity and the fluid conductivity. The flow rate is calculated by dividing the voltage by the product of the magnetic field strength and the fluid conductivity.



  • Ultrasonic: This technique uses a device that has ultrasonic transducers. The device emits and receives ultrasonic pulses or waves along or across the flow path. The pulses or waves are affected by the fluid as they travel through it. The effect can be measured in terms of time difference, frequency shift, phase shift, etc., which are proportional to the flow velocity. The flow rate is calculated by multiplying the effect by a calibration factor.



The advantages and disadvantages of each technique and method depend on various factors, such as:



  • The accuracy, repeatability, and resolution of the measurement.



  • The range, linearity, and turndown ratio of the measurement.



  • The sensitivity, stability, and robustness of the measurement.



  • The installation, calibration, and maintenance costs and requirements of the measurement.



  • The compatibility, interference, and influence of the fluid properties and conditions on the measurement.



The selection criteria and guidelines for choosing the best technique and method for a given situation depend on various factors, such as:



  • The purpose, objective, and specification of the measurement.



  • The type, state, and characteristics of the fluid to be measured.



  • The size, shape, and configuration of the flow path or pipe.



  • The environmental, operational, and regulatory conditions and constraints of the measurement.



  • The availability, accessibility, and affordability of the measurement.



The R W Miller Flow Measurement Engineering Handbook provides detailed information and guidance on the advantages and disadvantages, the selection criteria and guidelines, and the installation and calibration procedures and best practices for each technique and method for measuring flow.
