Comparison of the differences in the use of four commonly used flow meters

Abstract: The information on the difference and comparison of the use of four commonly used flowmeters is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Turbine Flowmeter When fluid flows through a turbine flowmeter, the fluid rotates the rotor. The rotational speed of the rotor is related to the velocity of the fluid. The flow or total is derived from the average flow rate of the fluid felt by the rotor. Turbine flow meters accurately measure clean liquids. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is a detailed comparison of the differences between the use of four commonly used flowmeters. Turbine Flowmeter When fluid flows through a turbine flowmeter, the fluid rotates the rotor. The rotational speed of the rotor is related to the velocity of the fluid. The flow or total is derived from the average flow rate of the fluid felt by the rotor. Turbine flow meters accurately measure clean liquids and gases. Like PD flowmeters, turbine flowmeters also produce unrecoverable pressure errors and also require moving parts. Electromagnetic flowmeter When a conductive fluid flows through an electromagnetic field, the velocity of the fluid can be obtained by measuring the voltage. Magnetic flow meters have no moving parts and are not affected by fluids. Conductive liquids are measured with high accuracy when the tube is full. The electromagnetic flowmeter of Shanghai Automation Instrument No. 9 Factory can be used to measure the flow rate of slurry fluid. The ultrasonic flowmeter propagation time method and the Doppler effect method are commonly used methods for ultrasonic flowmeters to measure the average velocity of the fluid. Like other velocity meters, it is a meter that measures volumetric flow. It is an unobstructed flowmeter, and if the ultrasonic transmitter is installed outside the pipeline, it does not need to be inserted. It is suitable for almost all liquids, including slurries, with high precision. But the contamination of the pipes can affect the accuracy. Vortex flowmeter The vortex flowmeter is to place a bluff vortex generator in the fluid, and the speed of the vortex is proportional to the speed of the fluid, so as to calculate the volume flow. Vortex flowmeters are suitable for measuring liquids, gases or steam. It has no moving parts and no dirt issues. Vortex flowmeters are noisy and require high fluid velocity to create vortices. Thermal mass flow meters measure fluid velocity by measuring an increase in the temperature of the fluid or a decrease in thermal sensor. Thermal mass flow meters have no moving parts or holes and can accurately measure the flow of gas. Thermal mass flow meters are one of the few technologies that can measure mass flow, and are also one of the few technologies used to measure large-bore gas flow. Coriolis flowmeter This flowmeter uses a vibrating fluid tube to create a deflection corresponding to mass flow to measure. Coriolis flowmeters can be used to measure the mass flow of liquids, slurries, gases or steam. High accuracy. However, regular maintenance of the pipe wall is required to prevent corrosion. Measurement principle: Faraday's law of electromagnetic induction states that a conductor moving in a magnetic field will induce an electric potential. Using the principle of electromagnetic measurement, the fluid is a conductor in motion. The induced potential is proportional to the flow rate and is detected by two measuring electrodes, which are then amplified by the transmitter to calculate the flow rate based on the cross-sectional area of ​​the pipe. A constant magnetic field is produced by switching DC currents with alternating polarity. The measurement system consists of a transmitter and a sensor. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
