Gas metal tube float flow meter ensures more accurate accuracy during use

Abstract: In the process of using the gas metal tube float flow meter, more accurate information to ensure the accuracy is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. As a high-precision measuring instrument, the wrong operation in use will have a great impact on the results. Therefore, mastering the correct operation method is nothing more than the main way to make the measurement results more accurate, so how to operate Woolen cloth? . More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the article to ensure more accurate accuracy during the use of gas metal tube float flowmeters. As a high-precision measuring instrument, the wrong operation in use will have a great impact on the results. Therefore, mastering the correct operation method is nothing more than the main way to make the measurement results more accurate, so how to operate Woolen cloth? (1) Before installing the metal tube rotameter, check whether the pipeline vibrates. If the pipeline vibrates, it will affect the movement of the float, resulting in inaccurate measurement results. (2) When measuring the flow rate of the gas medium, it is necessary to pay attention to the safety of the discharge at the outlet. If the high-speed air flow does not decelerate, it will cause a huge impact on the outside world. (3) It is necessary to judge the impurities in the medium. During the flow process, the movement of the float of the metal tube float flowmeter will be affected, resulting in the action of external force, and even chemical reactions will occur, which will make the float lose its function. Therefore, a filter with strong magnetic force should be installed at this time to filter out metal ions. If there are solid particulate impurities in the pipeline, these impurities will impact the float during the flow, change its motion curve, and affect the physical properties of the medium, making the measurement inaccurate. (4) After checking that there is no vibration in the pipeline, the metal tube rotameter should be installed vertically on the pipeline, because if it is inclined, the metal tube rotameter cannot correctly display the floating height of the float, so the space area above the float cannot be calculated, and the accuracy cannot be obtained. measurement results. Metal tube float flowmeter is a variable area flow meter based on float position measurement. It has the characteristics of simple structure, intuitive, small pressure loss and convenient maintenance. Gas metal rotameter is one of the most commonly used flowmeters in industry and laboratories. Our company believes that it is necessary to evaluate the measurement error of the gas metal rotameter's indication error separately. The specific steps are as follows: 1. Measurement basis of the metal tube rotameter: According to the verification regulations, the calibration of the indication error of the gas metal tube rotameter shall adopt the standard table method on the standard device of gas flow rate of the sonic nozzle. 2. Environmental conditions of metal tube float flowmeter: temperature requirement: (5～35)℃; humidity requirement: atmospheric relative humidity is (45%～75%)rh; atmospheric pressure requirement: (86～106)kpa. 3. Measurement standard of metal tube float flowmeter: standard device for gas flow rate of sonic nozzle, working range DN (15 ~ 200) mm diameter. Sonic (speed nozzle gas flow standard device mainly consists of annular water vacuum pump, pressure stabilizer tank, calibration table, sonic nozzle, timing counter, upper computer, etc.) 4. Metal tube float flowmeter Measured object: gas metal tube float flow The accuracy level is 2.5. Fifth, the use of the evaluation results of the metal tube float flowmeter: in the case of meeting the above conditions, theφ25mm gas metal rotor flowmeter, measuring range (2.5～25)m3/h, generally can directly use this uncertainty evaluation result; for other flowmeters, this uncertainty can be used according to the type of flowmeter and measuring range The degree of evaluation method gives the corresponding evaluation results. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
