Inventory of turbine flow sensor six key points of maintenance

The so-called turbine turbine flow sensor is used to measure flow special 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 formed by the amplifier amplification with a certain amplitude of continuous rectangular pulse, remote transmission to display instrument, display instantaneous flow and cumulative measurements of the fluid. Turbine flow sensor manufacturer engineer to tell you, in the maintenance of products should pay attention to the following 6 points: 1, the operation, need to 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 medium, it is forbidden to make the impact of high velocity. The maintenance period of 3, sensors, general control in the six months or so. 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. Flow sensor factory engineer said: its products are widely used in oil, organic liquid and inorganic liquid, liquefied petroleum gas, natural gas and low temperature in actual measurement of the fluid. According to the above points, and its maintenance should also pay special attention to.
