According to the difference of detection volume, flow measurement methods can be divided into volume flow detection and mass flow detection. According to different detection principles, flow measurement methods can be divided into speed method, volume method and mass method.
1. Velocity method: The velocity method is to measure the average flow rate of the fluid in the pipeline by the flow rate, and then multiply it by the cross-sectional area of the pipeline to obtain the volume flow rate of the fluid. Flow detection instruments based on this detection method include differential pressure flowmeters, rotameters, electromagnetic flowmeters, and ultrasonic flowmeters.
2. Volumetric method: The volumetric method is to continuously measure the flowing medium with a standard fixed volume per unit time, and calculate the flow rate with a fixed volume of the discharged fluid. Flow detection instruments based on this detection method include oval gear flow meters, piston flow meters, and scraper flow meters.
3. Quality method: There are two types: direct method and indirect method. Direct mass flow meters directly measure mass flow, such as angular momentum, calorimetry, and Coriolis force. The indirect mass flowmeter measures the volume flow rate and the density of the fluid at the same time and automatically calculates the mass flow rate. The measurement accuracy of mass flowmeter is not affected by the temperature, pressure and density of the fluid, and it is a new type of instrument that is under development.

Flow measurement: a complete buying guide:
The measurement and adjustment of fluid flow is an important part of industrial production. Flow measurement needs to use flow meters. How much do you know about this content? This guide will give you a detailed introduction to the relevant content of flow measurement, and then read on.
1. What is flow measurement
The amount of fluid passing through a certain cross-sectional area of the pipeline per unit time is called flow rate. To measure them, flow measuring instruments are needed. Flow measuring instruments are industrial automation instruments used to measure the flow of fluids such as liquid, gas or steam in pipes or open channels, also known as flow meters.
With the development of science and technology, measuring instruments have begun to develop in the direction of precision and miniaturization. Flow can be measured indirectly by various physical phenomena, so there are many types of flow measuring instruments. According to the measurement method, the flowmeter has differential pressure type, variable area type, volume type, velocity type and electromagnetic type.
2. Benefits of Flow Measurement
(1) It is suitable for a variety of measurement conditions, and can output measurement data of flow, water level, and flow.
(2) It is suitable for various cross-sections such as trapezoid, circular, U-shaped, etc., and the parameter setting of the cross-section is simple and convenient.
(3) Convenient configuration software, which can conveniently configure parameters according to actual needs and adapt to different conditions of use.
(4) Expandable array type multi-point flow measurement, equipped with a set of flow meters and multiple sets of flow meters, through the flow meter internal algorithm fitting, to achieve large cross-section flow measurement.
(5) Non-contact measurement, combined with cross-section parameters to calculate the flow rate, is not affected by wind, temperature, haze, sediment, and floating objects, and has a rain-proof mode.
3. How Flow Measurement Works
There are many types of flow measuring instruments, and different types have different working principles. The common ones are impeller flowmeters, turbine flowmeters, electromagnetic flowmeters, and ultrasonic flowmeters. The principles of these four flowmeters are introduced below.
(1) Impeller flowmeter
The sensor is divided into a transmitter and a turbine. The turbine is in direct contact with the fluid, and the transmitter is isolated from the fluid. The liquid flow drives the flexible rotating turbine to rotate. There are four uniformly distributed blades on the turbine, and each blade is solidified with a strong magnetic sheet. The rotating magnetic sheet will make the transmitter Hall switch produce a frequency signal proportional to the flow rate, and the transmitter will convert the frequency signal into a 4-20mA current signal.
(2) Turbine flowmeter
A turbine is installed in the center of the pipeline, and both ends are supported by bearings. When the fluid passes through the pipeline, it impacts the turbine blades and causes the turbine to rotate. The angular velocity of the turbine rotation is proportional to the flow rate of the fluid. The liquid flow drives the turbine to rotate, cutting the magnetic lines of force generated by the magnetic steel in the housing, and generating magnetic flux changes. The sensing coil sends the detected magnetic flux periodic change signal to the preamplifier for amplification, and generates a pulse signal proportional to the flow rate, and the flow value is obtained through circuit calculation.
(3) Electromagnetic flowmeter
The electromagnetic flowmeter is designed according to Faraday's law of electromagnetic induction. A pair of detection electrodes are installed on the tube wall where the axis of the measuring tube and the magnetic field lines are perpendicular to each other. When the conductive liquid moves in an alternating magnetic field along the measuring tube and the magnetic field lines move in a vertical direction, the conductive liquid cuts the magnetic field lines to generate an induced electric potential, which is detected by the two detection electrodes on the measuring tube.
(4) Ultrasonic flowmeter
The principle of ultrasonic measurement of flow velocity is that the propagation velocity of ultrasonic waves in the fluid will vary with the flow velocity of the fluid being measured. Set up one probe at each upstream and downstream of the pipeline, use fluid to propagate ultrasonic waves, and use time-frequency method to measure flow velocity. After transformation, the instantaneous flow can be displayed.
4. Industries using Flow Measurement
Impeller flow meters can be widely used in water treatment and regeneration, cooling water monitoring, filtering systems, process treatment and manufacturing industries, swimming pools, chemicals, heat exchangers, water pump protection, liquid supply systems and other use scenarios. But it cannot be used in an environment where the water quality is too bad, because the impurities in the water will wrap the turbine and make it unable to rotate freely, resulting in measurement errors.
Turbine flowmeter has the characteristics of simple structure, high accuracy, easy installation, maintenance and use. Used in petroleum, chemical, metallurgy, water supply, papermaking, environmental protection, food and other fields. It can measure the volume flow of liquids such as water, pure water, tap water, sewage without impurities, diesel, gasoline, and low-viscosity crude oil.
Electromagnetic flowmeters are suitable for measuring the volume flow of conductive liquids and slurries in closed pipelines, such as clean water, sewage, various acid-base salt solutions, mud, paper pulp, and food liquids. It is widely used in metallurgy, papermaking, water treatment, chemical industry, electric power and other industries.
Ultrasonic flowmeter is a new type of flow measurement instrument developed in modern times. It has been widely used in medical, ocean observation, river and other aspects of measurement. As long as the fluid that can propagate ultrasonic waves can be measured with an ultrasonic flowmeter. The flowmeter can also measure the flow of high-viscosity liquids, non-conductive or gas.
5. Flow Measurement Maintenance Process
The flow meter must be used properly and daily maintenance and management must be strengthened to achieve satisfactory results. Poor installation, improper use, and poor maintenance and management often lead to loss of accuracy or early damage to the instrument, causing losses to production, which are not uncommon in actual work.
(1) When it must be installed vertically, the liquid should flow from bottom to top to ensure that the flowmeter body is full of liquid.
(2) In order to ensure high measurement accuracy, the flowmeter should be installed horizontally on a horizontal pipeline, and the arrow mark on the flowmeter indicating the flow direction should be consistent with the liquid flow direction.
(3) In order to eliminate the influence of uneven flow velocity distribution in the pipeline on the measurement accuracy. A certain straight section should be installed upstream and downstream of the flowmeter, or a rectifier should be installed to replace some straight sections.
6. Future of Flow Measurement
There are many types of flow meters and a wide range of applications. Due to the measurement medium, such as liquid, gas, steam, etc., and the different working conditions, there are different requirements for the instrument. Therefore, it is necessary to understand the working principle, structural performance, characteristics of the measured medium, flow status, pipeline conditions and the requirements of the production process for the instrument, and correctly select the appropriate instrument.
With the development of industrial production and the need to save energy, more and more people pay attention to flow measurement. Flow meters have been widely used, and flow measurement technology has achieved rapid development, which will play an important role in realizing the automation of a production process, ensuring safe production, and improving economic benefits.
In order to meet the special requirements of flow measurement, with the development of new technologies, some new flow measurement instruments have appeared. For example, a Doppler laser flow meter can measure the velocity of airflow changes in the jet element, supersonic airflow and turbulence, and combustion flames. Especially it can measure the velocity distribution. The development of flow measurement instruments will become more and more perfect.
