What do you know about the three commonly used flow meters and their working principles?

The three commonly used flow meters are electromagnetic flow meters, turbine flow meters, and vortex flow meters. Their working principles and characteristics are as follows: The working principle of electromagnetic flow meters is based on Faradays law of electromagnetic induction.. The conductive medium inside the measuring tube is equivalent to a conductive metal rod in Faradays test, with two electromagnetic coils at the upper and lower ends generating a constant magnetic field. When a conductive medium flows through, an induced voltage is generated, which is measured by two electrodes inside the pipeline. The Qihe measurement pipeline achieves electromagnetic isolation from the fluid and measurement electrodes through non-conductive lining (such as rubber, Teflon, etc.). Job characteristics: Equipped with a bidirectional measurement system. The straight pipe section required for the sensor is relatively short, with a length of 5 times the diameter of the pipeline. Low pressure loss. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. Mainly used in sewage treatment. Working principle of turbine flowmeter: Within a certain flow range, the speed of the turbine is proportional to the flow velocity of the fluid. The fluid flow drives the turbine to rotate, and the speed of the turbine is converted into electrical pulses, which are displayed on a secondary meter to reflect the fluid flow rate. Job characteristics: Strong ability to resist impurities. Strong resistance to electromagnetic interference and vibration. The structure and principle of tremor disper

sion are simple and easy to maintain. Almost no pressure loss, saving power consumption. The working principle of vortex flowmeter is to measure the flow rate based on the principle of fluid oscillation. When the fluid passes through the vortex flow shed transmitter in the pipeline, two columns of vortices proportional to the flow velocity are alternately generated up and down behind the vortex generator in the triangular column. The release frequency of vortices is related to the average velocity of the fluid flowing through the vortex generator and the characteristic width of the vortex generator. Based on this relationship, the average velocity of the fluid flowing through the vortex generator can be calculated by the vortex frequency, and then multiplied by the cross-sectional area to obtain the flow rate. Job characteristics: The structure is simple and sturdy, with no movable parts, high reliability, and very reliable for long-term operation. Easy to install and very convenient to maintain. The detection sensor does not directly contact the measured medium, with stable performance and long lifespan. The output is a pulse signal proportional to the flow rate, with no zero drift and high accuracy. The measurement range is wide, and the range ratio can reach 1:10. Less pressure loss, lower operating costs, and more energy-saving significance.
