Application occasions
Turbine flowmeter [1] is a speed meter, it has high accuracy, good repeatability, simple structure, high pressure resistance, wide measurement range, small size, light weight, small pressure loss, long life, simple operation, convenient maintenance And other advantages, used to measure the volume flow and accumulation of low-viscosity, non-corrosive, clean liquids in closed pipelines. It can be widely used in petroleum, chemical, metallurgy, organic liquid, inorganic liquid, liquefied gas, urban gas pipeline network, pharmaceutical, food, papermaking and other industries.
Working Principle
Turbine flowmeter is the main type of velocity flowmeter. When the measured fluid flows through the turbine flowmeter sensor, under the action of the fluid, the impeller is rotated by force, and its speed is proportional to the average flow velocity of the pipeline. At the same time, the blades are periodic Ground cutting of the magnetic field lines generated by the electromagnet changes the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating electric potential signal, that is, an electric pulse signal, is induced in the coil. The frequency of the electric pulse signal is proportional to the flow rate of the fluid to be measured.
Turbine flowmeter has the advantages of high accuracy, good repeatability, no zero drift, high turndown ratio and so on. Turbine flowmeter has high-quality bearings and specially designed guide vanes, so it greatly reduces wear and is not sensitive to peaks. It can also give reliable measurement variables under harsh conditions. The output signal of the turbine flowmeter is pulse, which is easy to digitize. The pressure loss of the turbine flowmeter is small, the blade can be anticorrosive, and it can measure viscous and corrosive media.
