Gas metal pipe flow meter scale in use process to ensure more accurate precision

Abstract: the gas tube flow meter scale in use process to ensure accuracy is more accurate information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Metal tube flow meter as a high precision measuring instruments, in the use of the wrong operation can produce great influence on the result, therefore, the right operation method is the main way to make more accurate measurement results, so how to operate? 。 More flow meter manufacturers choose model price quote you are welcome to inquire, here is the gas tube flow meter scale in use process to ensure more accurate precision article details. Metal tube flow meter as a high precision measuring instruments, in the use of the wrong operation can produce great influence on the result, therefore, the right operation method is the main way to make more accurate measurement results, so how to operate? （ 1) Before the installation of metal tube float flowmeter should check whether the pipeline vibration, if the pipe vibration will affect the movement of the float, leading to inaccurate measurements. （ 2) When measuring the flow of gas medium, discharge of security problems, need to pay attention to export high-speed airflow if without slowing down can cause huge impact to the outside world, 3) To determine the impurity elements in the medium, if are some metal impurity, in the process of flow will affect the movement of the float tube float flowmeter, the role of external force, more what happen chemical reaction, make float loss function, so at this time to install the strong magnetic filter, filter out metal ions. If the pipe has a solid particle impurity, these impurities in the process of flow will cause impact to float, change its motion curve, and affect the physical properties of medium, the measurement is not allowed. （ 4) After check the pipeline no vibration, will tube flow meter installed in vertical pipe runs, because of metal tube float flowmeter can't correct the tilt indicates the rise height of the float, and therefore cannot be computed float above the space area, can't get accurate measurement result. Metal pipe flow meter is based on the float position measuring a variable area flow meter, it has the structure is simple, intuitive, small pressure loss, easy maintenance, etc. Gas metal flow meter is a kind of commonly used industrial and laboratory zui flowmeter, my company consider it necessary to separate the metal gas float flowmeter measurement error of error evaluation. Specific steps are as follows: first, metal tube flow meter measurement basis: according to provisions of verification regulation of gas metal flow meter calibration of error in the sonic nozzle gas flow standard device with a standard table method. Second, the metal flow meter environmental conditions: temperature requirements: ( 5 ~ 35) ℃; Relative humidity of atmosphere humidity requirements: ( 45% ~ 75%) rh; (atmospheric pressure requirements 86 ~ 106) kpa。 3 and metal pipe float flowmeter measurement standards: sonic nozzle gas flow standard device, scope of work DN ( 15-200) Mm. The sound ( Speed nozzle gas flow standard device mainly include water ring vacuum pump, buffer tank, calibration, sonic nozzle, timing counter, upper machine and so on. ） Four, metal tube flow meter measured object: gas tube flow meter, accuracy degree of 2. Level 5. Five, the use of metal tube float flowmeter evaluation results: under the condition of the accords with afore-mentioned conditions, for & phi; 25 mm gas metal rotameter, measurement range, 2. 5 ~ 25) M3 / h, general can directly use the uncertainty of evaluation results; For other flow meter, according to the type of flow meter and measuring range, can adopt the evaluation methods of uncertainty present the corresponding evaluation results. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
