Count of turbine flow sensor six key points of maintenance

So-called turbine turbine flow sensor is used to for the flow measurement of its working principle is a special sensor Ms. Sheng when liquid flows through the sensor shell, the impeller blade and flow direction to form a certain Angle, fluid impact blade torque production. After overcoming friction torque and the flow resistance of rotating blades. After a moment is balanced, speed is stable. Below in some cases, the speed is proportional to the speed. Because the blade is permeable, so it is a magnetic field. Rotor blades to cut off the magnetic field lines, periodically change the magnetic current coil. Electrical pulses at the ends of the coil so through it. After the amplifier to form a certain amplitude of continuous rectangular pulse wave, from it can remote transmission, display the current flow value and a cumulative measure of the liquid. 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, the media should slowly into the sensor, and then open the exhaust valve if if the sensor is in a state without medium, is strictly prohibited by the influence of the liquid. The maintenance period of 3, sensors, general control in the six months or so. In the process of maintenance and cleaning, please note that don't damage measurement indoor parts, especially the impeller. Assembly, please pay attention to the orientation and the position of the impeller. 4, when the sensor is dry in a dry place, should protect sensor is not affected by the internal. 5, filter clean on a regular basis. In the internal medium cleaning should be performed at the same time. 6, before the installation of sensors, let its fast with air nozzle or manually pull the wheel rotation, to see whether there is any display, display and then choose to install the sensor. There is no evidence, check the corresponding parts and correct mistakes. Flow sensor factory engineer said: he's products are widely used in oil, organic liquid and inorganic liquid, liquefied petroleum gas, natural gas and cryogenic liquid of actual measurement has been used. According to the above points, should pay special attention to the maintenance work.
