When the fluid to be measured flows through the turbine flowmeter sensor, under the action of the fluid, the impeller is forced to rotate, and its rotation speed is equal to the average flow velocity of the pipeline. In proportion, at the same time, the blade periodically cuts the magnetic lines generated by the electromagnet and changes the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating potential signal, that is, an electric pulse signal, is detected in the coil, and the frequency of the electric pulsating signal is measured. The flow rate of the fluid is proportional.Colour:Random ColorMaterial:plasticSize:10 x 7.4 x 5.5cmPackage Contents:2 x turbine flow meter (with battery)Random colors are not optionalOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
