The principle of metal tube rotameter scale calibration precision

by:Sincerity     2020-10-29
Abstract: metal tube rotameter scale verification accuracy of measurement on the principle of information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. The third generation of metal tube float flowmeter by changzhou into abundant professional research and development, than the traditional metal tube rotameter with high precision, good repeatability, and the advantages of small services, by a measurement of tube and a local indicator, with the five. Choose metal tube. More flow meter manufacturers choose model price quote you are welcome to inquire, here is a metal tube rotameter scale calibration principle of measuring precision of the article details. By professional research and development, the third generation of metal tube float flowmeter than traditional metal tube rotameter with high precision, good repeatability, and the advantages of small services, by a measurement of tube and a local indicator, with the five. Choose metal tube rotor flow time, must first understand the metal tube rotameter manufacturing enterprises have adopted product standards, especially about the precision of the regulations and the provisions of the display scale, secondly to know is the product of manufacturing and technology level. At the same time, need based on technological requirements in the flow measurement, especially in the measurement and control requirements of high precision, scale display intuitive, medium high viscosity of various circumstances, to choose can be directly display medium flow rate, density and viscosity of the compensation performance of metal tube rotameter. Because of the scale conversion and validation is done according to the medium conditions. Choose the appropriate measurement component materials. General should choose good anti-corrosion performance measurement of material. Only guarantee the float and measuring the corrosion of parts for a long time from the medium, to ensure the accuracy of product long-term work in the factory. Work flow is lower than the 50% range, the absolute error in the measurement point on the increase, is not conducive to control precision. For manufacturing enterprise with density and viscosity correction ability, it is particularly important. Because, density and viscosity differences, will directly affect the calibration of flow calibration. To directly show the water or air flow calibration of flowmeter calibration conditions, may require manufacturing enterprises to provide calibration certificate data and flowmeter, in actual use instrument, according to the density correction calibration data and calculations by hand. For which has the function of control tube rotameter, try choosing products with communication function. When the medium conditions change, can take advantage of the communication function of products, the scene to adjust signal, zui big limit to ensure product accuracy. Conditional user, can according to the flow meter manufacturers provide flow calculation and calibration records for inspection instrument. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
