Application of Turbine Flow Meter and Secondary Instrument

Abstract: The application information of turbine flow meter and secondary instrument is provided by excellent flow meter and flow meter manufacturers. The working principle of the turbine flow sensor is that when the fluid flows through the sensor housing, since the impeller blades have a certain angle with the flow direction, the impeller of the fluid has a rotating torque, and the blades rotate after overcoming the friction torque and fluid resistance, and the torque is balanced. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the application article details of turbine flowmeters and secondary instruments. The working principle of the turbine flow sensor is that when the fluid flows through the sensor housing, because the impeller blades have a certain angle with the flow direction, the impeller of the fluid causes the blades to have a rotating torque, and the blades rotate after overcoming the friction torque and fluid resistance, and after the torque balances The rotating speed is stable. Under certain conditions, the rotating speed is proportional to the flow rate. Because the blade is magnetically permeable, it is in the magnetic field of the signal detector. The rotating blade cuts the magnetic field line and periodically changes the magnetic flux of the coil, so that the two ends of the coil are The electric pulse signal is induced, and the signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument to display the instantaneous flow and accumulated volume of the fluid. Turbine flow sensors are widely used in the measurement of petroleum, organic liquids, inorganic liquids, liquefied gas, natural gas and cryogenic fluids. The connection between the turbine flow sensor and the single-chip microcomputer 1. The turbine flow sensor is a precision flow measuring instrument, which can be used to measure the flow and total amount of liquid together with the corresponding flow accumulating instrument. It is widely used in metering and control systems in petroleum, chemical, metallurgy, scientific research and other fields. Turbine flow sensors with sanitary fittings can be used in the pharmaceutical industry. 2. The structure of the integrated turbine flowmeter is an explosion-proof design, which can display the total flow, instantaneous flow and flow full percentage. The battery adopts long-term lithium battery, the battery life of the single-function accumulator can reach more than 5 years, and the battery life of the multi-function display watch can also reach more than 12 months. 3. The integrated meter can display many flow units, including cubic meters, gallons, liters, standard cubic meters, and standard liters. The fixed pressure and temperature parameters can be set to compensate for the gas, and the instrument can be used for fixed compensation accumulation when the pressure and temperature parameters do not change much. 4. The output of the turbine flowmeter sensor is a sine wave signal, which needs to be shaped into a square wave by an integer circuit, and then connected to the IO port of the microcontroller to count pulses, and the flow rate is proportional to the number of pulses. The maintenance of the turbine flow sensor should pay attention to the following points: 1. Keep the measured medium clean and free from impurities such as fibers and particles during use. 2The maintenance period of the turbine flow sensor is generally half a year. When overhauling and cleaning, please be careful not to damage the parts in the measuring chamber, especially the impeller. When assembling, please pay attention to the positional relationship between the guide and the impeller. 3. When the turbine flow sensor is not in use, the internal medium should be cleaned and dried, and protective sleeves should be placed on both ends of the sensor to prevent dirt from entering, and then stored in a dry place. 4. The filter used should be cleaned regularly. When not in use, the internal medium should be cleaned like the sensor, and the dust jacket should be added and stored in a dry place. 5Before the sensor is installed, use the mouth to blow the impeller or turn the impeller by hand to make it rotate quickly to observe whether there is a display. When there is a display, install the sensor. If there is no display, check the relevant parts to troubleshoot.
