Correct use of LZB series glass rotor flow meter

Abstract: The information on the correct use of LZB series glass rotor flowmeters is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. LZB series glass rotor flowmeter is a commonly used flow measuring instrument, which is mainly used for inspection in chemical, petroleum, light industry, medicine, environmental protection, food and other industries. Users need to master certain precautions when using LZB series glass rotor flowmeter, as follows. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details of the correct use of LZB series glass rotor flowmeters. LZB series glass rotor flowmeter is a commonly used flow measuring instrument, which is mainly used for inspection in chemical, petroleum, light industry, medicine, environmental protection, food and other industries. Users need to master certain precautions when using LZB series glass rotor flowmeters. The following will introduce the precautions for the use of LZB glass rotor flowmeters, hoping to help everyone. How to use the LZB series glass rotor flowmeter correctly, and what are the factors that affect the measurement accuracy? 1. Before installing the glass rotor flowmeter, it is necessary to take out the top lining of the flowmeter for transportation and maintenance needs. And check whether the cone tube is damaged, whether the float can move up and down freely, and install it only after checking the normal condition. 2. Before using the glass rotor flowmeter, you should check whether the technical parameters such as flow range, accuracy level, working pressure, temperature and other parameters meet the needs of the work site. 3. The glass rotameter must be installed in a vertical position (the angle between the center line of the flowmeter and the vertical line of the lead does not exceed 5°C) and be properly supported to prevent any external force from being introduced. When installing, the smallest tapered end of the inlet tapered pipe, that is, the smallest numerical scale end, is located at the lower part. 4. When installing, it is necessary to prevent the glass rotor flowmeter from being damaged by excessive external force, such as pressure and twist. 5. The newly installed pipeline must be flushed clean. 6. The fluid to be measured cannot be mixed with large particles of dirt, otherwise the float will be stuck or blocked. If necessary, according to the different working conditions in use, install a filter upstream of the glass rotor flowmeter to prevent impurities from contaminating and jamming. Plug rotor flowmeter, affecting normal use. 7. The fluid pressure measured by the flowmeter must be stable. If the fluid is unstable and there is a pulsating flow, it cannot be measured correctly. In order to ensure the excellent measurement of the rotameter, a buffer can be installed to eliminate the pulsating flow. 8. When the rotameter is in use, the control valve on the upstream pipeline of the flowmeter should be slowly unscrewed first, and then the regulating valve should be used to adjust the flow, so as to prevent the sudden opening of the float from causing the rapid rise of the float and damaging the conical pipe. 9. In order to obtain accurate measurement data, it is advocated that the common flow rate of the measured fluid should be more than 60% of the indexed flow rate of the rotameter. 10. It should be avoided that the temperature of the fluid to be measured changes rapidly, and it cannot be hot and cold. There will be a certain deviation in the measurement of different temperatures. 11. When the conical tube and the float are found to be stained during use, they should be cleaned in time. If leakage is found during use, it is generally the failure of the sealing ring, which should be replaced in time. 12. It is important to note that the flowmeter is divided into ordinary and anti-corrosion. Do not use ordinary to measure corrosive fluids. 13. Another point is that the flowmeter must choose products produced by qualified manufacturers. The purchase of flowmeters depends not only on price, but also on qualifications, whether the manufacturer has the qualification to produce flowmeters, and whether it has a complete after-sales service system. , Whether the quality assurance is in place. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'LZB series glass rotor flow meter correct use method'
