About how much do you know about the maintenance of turbine flow sensor

by:Kaidi Sensors     2021-03-18
The turbine turbine flow sensor is used to measure flow sensor. Its working principle is when the fluid flows through the sensor shell, because of the impeller blade and flow direction with a certain Angle, fluid impulsive make blades rotating torque generated. To overcome the friction torque and fluid resistance, blade rotation. After moment balance, speed stability. Under certain conditions, the speed is proportional to the velocity. Because the blade with magnetic conductivity, so it in the magnetic field signal detector. In the magnetic field, rotating blades to cut off the magnetic field lines, periodically change coil magnetic flux, creates an electrical signal on both ends of the coil. Signal by the amplifier amplification plastic forming has certain amplitude of continuous rectangular pulse wave, transmission and display instrument, display instantaneous flow and cumulative measurements of the fluid. What problem should be paid attention to the maintenance of turbine flow sensor? Following quickly hear flow sensor manufacturer engineers how to say: a, when using, should be kept clean measured medium, no fiber, particles and other impurities. Second, before open the outlet valve, turbine flow sensor should be slowly toward injection medium in the sensor. When the sensor is in a state of no medium, is strictly prohibited by the high velocity impact. Three, the maintenance period of turbine flow sensor for half a year. Repair and clean, please take care not to damage measurement indoor parts, especially in the impeller. When assembling, please pay attention to the position of the guide vane and the impeller. Four, when not using a turbine flow sensor, the internal medium of the sensor at the ends of the cleaning, drying and protection, prevent dirt to enter, and then stored in a dry place. Fifth, regular cleaning filter. When cleaning, should be simultaneous interpretation of the internal medium. Six, before the installation of sensor and blow or hand make it rapidly rotating impeller, observe whether there is a show that has shown when installing sensors. If there is no display, check the related parts and troubleshooting. Turbine flow sensor manufacturer engineers finally mentioned, their products are widely used in oil, organic liquid and inorganic liquid, liquefied petroleum gas, natural gas and low temperature measurement. When maintenance will need to pay special attention to the above points.
