Principles of Measuring Accuracy of Metal Tube Rotameter Meters

Abstract: The principle information for the verification of measurement accuracy of metal tube rotor flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The third-generation metal tube rotameter is professionally developed by Changzhou Chengfeng. Compared with the traditional metal tube rotameter, it has the advantages of high precision, good repeatability and small service volume. It consists of a measuring tube and a local indicator. 5 items. Choose a metal tube. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the principle article for the verification of measurement accuracy of metal tube rotor flowmeters. The third-generation metal tube rotameter is professionally researched and developed. Compared with the traditional metal tube rotameter, it has the advantages of high precision, good repeatability and small service volume. It consists of a measuring tube and a local indicator, and has 5 items. When choosing a metal tube rotameter, the first thing to understand is the product standards implemented by the metal tube rotameter manufacturer, especially the regulations on accuracy and the regulations on display scale, and the second thing to understand is the manufacturing and technical level of the product. At the same time, it is necessary to combine the process requirements in flow measurement, especially when the measurement or control requires high precision, intuitive scale display, and high viscosity of the medium, it is necessary to choose to display the medium flow very directly, with density and viscosity compensation performance. metal tube rotameter. Because the conversion and calibration of the scale are completed according to the media conditions. Select the appropriate measuring part material. Generally, the measurement material with good anti-corrosion performance should be selected. Only by ensuring that the float and measuring components are not corroded by the medium for a long time, can the product work for a long time to the accuracy requirements at the factory. When the normal working flow is lower than 50% of the range, the absolute error on the measuring point increases, which is not conducive to the control accuracy. This is especially important for manufacturers with density and viscosity correction capabilities. Because the difference in density or viscosity will directly affect the calibration of the flow scale. For a flowmeter that directly displays the water or air flow scale under calibration conditions, the manufacturer may be required to provide calibration data and a flowmeter certificate. Correction. For metal tube rotameters that require control functions, try to choose products with communication functions. When the medium conditions change, the communication function of the product can be used to adjust the signal on the spot to ensure the maximum product accuracy. Conditional users can re-inspect the meter according to the flow calculation book and calibration record provided by the flowmeter manufacturer. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Principles for Verification of Measurement Accuracy of Metal Tube Rotameters'
