What are the commonly used flow meters for measuring liquids?

Abstract: What are the commonly used flow meters for measuring liquids? The information is provided to you by the excellent manufacturers of flowmeters and flowmeters. What are the commonly used flowmeters for measuring liquids? The details are as follows: *. Volumetric flowmeter Volumetric flowmeter (also known as fixed displacement flowmeter) is a total measurement instrument with the highest accuracy. According to its measuring element, it can be divided into spiral rotor (double rotor) flow. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. What are the flowmeters that are commonly used to measure liquids? Article details. What are the commonly used flowmeters for measuring liquids? The details are as follows: First, the volumetric flowmeter The volumetric flowmeter (also known as the fixed displacement flowmeter) is a total measurement instrument with the highest accuracy. According to its measuring elements, it can be divided into spiral rotor (dual rotor) flowmeter, scraper flowmeter, oval gear flowmeter, disc flowmeter, rotary piston flowmeter, liquid-sealed rotary drum flowmeter, etc. The main features are as follows . (1) Advantages: high measurement accuracy; can be used for the measurement of high-viscosity liquids, suitable for clean single-phase fluids; direct-reading instruments can directly obtain the cumulative total flow without external energy; easy installation, no special requirements for front and rear straight pipe sections . (2) Disadvantages: not suitable for high and low temperature occasions; the type and caliber of the measured medium are limited; the pressure loss is large; regular calibration is required. (3) Application: Due to its high-accuracy measurement characteristics, positive displacement flowmeters are widely used in energy, petroleum, medicine, food, chemical and other fields, especially when measuring liquid media such as crude oil, which requires storage, transportation, handover and Distribution, etc. are measured and used as the basis for financial accounting or as the legal measurement of the contract between the buyer and the seller of the tax. Second, the differential pressure flowmeter Differential pressure flowmeter is one of the most used types of flow meters, and can be divided into orifice flowmeters, Venturi flowmeters, and uniform velocity tube flowrates according to the detection parts (primary meters). The main features are as follows. (1) Advantages: It has a wide range of applications and can measure all single-phase fluids and some miscible-phase fluids; the structure is simple and firm, the maintenance is convenient, and the service life is long; the detection parts, transmitters, and display instruments are produced by different manufacturers, which is convenient for scale and economic production. (2) Disadvantages: The measurement accuracy is general; the pressure loss is large (orifice plate, nozzle, etc.); the installation conditions are high, and there must be long enough straight pipes before and after it. (3) Application: As the earliest measurement method, in the flow measurement of closed pipelines, the differential pressure flowmeter can be applied to objects under various conditions. 4~1/3. Third, the Coriolis mass flowmeter The Coriolis mass flowmeter started late in the domestic application, but it can directly measure the mass flow of the fluid in the pipeline, and its main features are as follows. (1) Advantages: high measurement accuracy; wide range of measurement fluids, including liquids containing trace gases; no requirements for upstream and downstream straight pipe sections. (2) Disadvantages: low-density medium and low-pressure gas cannot be measured, and the gas content in the liquid will affect the measurement accuracy if it exceeds a certain limit; it is sensitive to external vibration interference, in order to prevent the influence of pipeline vibration, most of the sensors have higher requirements for installation and fixation; The pipe diameter is limited and cannot be used for larger pipe diameters; scaling in the measurement pipe or wear of the inner wall will affect the measurement accuracy; the pressure loss is large. (3) Application. Coriolis mass flowmeter is especially suitable for medium with high viscosity. Due to its high precision and stability, developed countries have used this kind of flowmeter in large quantities in chemical, pharmaceutical, petroleum, energy, food and other industrial fields. It is often used in the measurement of fluid pipeline transportation in the transportation sector. Fourth, ultrasonic flowmeter Ultrasonic flowmeter can be roughly divided into insertion type, pipe segment type, external clamp type and portable, etc. Its main characteristics are as follows. (1) Advantages: non-contact measurement, suitable for large diameter and large flow measurement; no pressure loss, no interference with fluid; suitable for any liquid; easy installation and maintenance. (2) Disadvantages: When there are bubbles or noise in the measured liquid, it will affect the measurement accuracy; the temperature range of the measurable fluid is limited by the temperature resistance of the ultrasonic transducer and the coupling material between the transducer and the pipeline, high temperature The raw data of the sound velocity of the fluid under test are incomplete. (3) Application. Ultrasonic flowmeters are widely used in petroleum, chemical, metallurgy, electric power and other fields. They are often used for flow measurement of factory discharge liquids, dirty process liquids, etc., as well as measurement on pipelines of west-east gas pipelines in operating areas. Fifth, the electromagnetic flowmeter In the 1970s and 1980s, there was a major breakthrough in electromagnetic flow technology, which made the use of the flowmeter continue to rise. Its main characteristics are as follows. (1) Advantages: suitable for measuring liquid-solid two-phase fluids containing solid particles; no pressure loss; not affected by fluid characteristics. (2) Disadvantages: liquids with low conductivity cannot be measured,Such as petroleum products and organic solvents, etc.; cannot be used for liquid measurement at higher temperatures; cannot measure gas, steam and liquids containing many larger bubbles. (3) Application. The medium and large diameter meters of electromagnetic flowmeters are often used in water supply and drainage projects; the medium and small diameter meters are often used in high-demand or difficult-to-measure occasions, such as strong corrosive liquids in the chemical industry, and paper pulp and black liquor in the paper industry; small and small diameters are commonly used. In the pharmaceutical industry, food industry, biochemical industry and other fields.
