Introduction to the turbine flow sensor of a few key points of maintenance

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 at an Angle, fluid force to rotate the blade to produce torque. To overcome the friction torque and fluid resistance, blade rotation. Torque, speed and stability. Under certain conditions, the speed is proportional to the flow. Because the blade has a magnetic permeability, its signal in magnetic field 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 continuous rectangular pulse amplitude, remote transmission to display instrument, display instantaneous flow and cumulative measurements of the fluid. Turbine flow sensor manufacturers engineer to tell you that the following points should be paid attention to in the maintenance of products: 1, when using, should maintain the cleanliness of measured medium, no fiber, the presence of the impurities such as particles. 2, the use of turbine flow sensor, should slow added medium to the sensors, and then open the outlet valve. Sensors in the state of the medium, is strictly prohibited by the high velocity impact. 3, the maintenance period of turbine flow sensor is usually half a year. In the process of maintenance and cleaning, please be careful not to damage measurement indoor parts, impeller, in particular, parts assembly, please pay attention to the orientation and the position of the impeller. 4, when the turbine flow sensor when not in use, the response to the internal medium cleaning, drying, and on both ends of the sensor, combined with cases, prevent dirt to enter, and then stored in a dry place. 5, regular cleaning filter. When cleaning, should be simultaneous interpretation of the internal medium. Before 6, installation of sensors, with a mouthpiece or hand make it rapidly rotating impeller, observe whether there is a display, a display and sensor installation. If there are no instructions, check the related parts and troubleshooting. Turbine flow sensor is widely used in oil, organic liquid and inorganic liquid, liquefied petroleum gas, natural gas and low temperature measurement of the fluid. According to the above points, and its maintenance should also pay special attention to.
