For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the application characteristics of turbine flowmeters and the details of their daily maintenance precautions. Turbine flowmeter product application characteristics and daily maintenance precautions Turbine flowmeter is a new type of speed instrument, it has high precision, good repeatability, simple structure, high pressure resistance, wide measurement range, small size, light weight, small pressure loss, It has the advantages of long life, simple operation and convenient maintenance. The temperature and pressure compensation instrument can integrate the detection functions of flow, temperature and pressure, and can perform automatic compensation of temperature, pressure and compression factor. , The ideal gas flow detection instrument for the volume flow and total amount of low-viscosity gas in the closed pipeline of the gas pressure regulating station and the gas heat measurement. Its working principle is that when the fluid flows through the sensor housing, because the impeller blades have a certain angle with the flow direction, the impetus of the fluid makes the blades have rotational torque, and the blades rotate after overcoming the friction torque and fluid resistance, and the rotational speed is stable after the torque is balanced. Under certain conditions, the rotational 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 lines, periodically changing the magnetic flux of the coil, so that electricity is induced at both ends of the coil. Pulse signal, which 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 cumulative volume of the fluid. In order to ensure the long-term normal operation of the gas turbine flowmeter, it is necessary to check the operation status of the flowmeter frequently, do maintenance work, and eliminate problems in time. Turbine flowmeter product application features 1. 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 totalizer. 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. Before the turbine flowmeter is put into operation, the instrument coefficient must be set, and the meter must be checked carefully to ensure that the flowmeter is correctly wired and well grounded before powering on. 2. Keep the measured medium clean and free from impurities such as fibers and particles during use. Keep the filter clear. If the filter is blocked by impurities, it can be judged from the increase in the difference between the pressure gauge readings at its inlet and outlet, and the blockage should be removed in time, otherwise, the flow will be seriously reduced. 3. The maintenance cycle of the turbine flow sensor is generally half a year. Periodically clean, inspect and recalibrate the flowmeter. For flowmeters equipped with lubricating oil or cleaning fluid injection ports, lubricating oil or cleaning fluid should be injected regularly according to the requirements of the manual to maintain the good operation of the impeller. 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. 4. When the turbine flow sensor is not in use, the internal medium should be cleaned and dried, and protective sleeves should be added at both ends of the sensor to prevent dirt from entering, and then stored in a dry place. 5. Monitor the status of the display meter, evaluate the display meter reading, and check in time if there is any abnormality. 6. The equipped filter 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. 7. Before the sensor is installed, blow the impeller by mouth 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. 8. For large-flow trade settlement measurement, in order to ensure the accuracy of the flow meter,The flowmeter must be calibrated frequently. The site should be equipped with on-line calibration equipment, or equipped with a mobile calibration device. Although the one-time investment is large, it is worthwhile considering the long-term economic benefits.
