The selection of the metal tube rotameter, we must first understand the standard metal tube rotameter product manufacturers performed, a predetermined moment of particular provisions also display accuracy, and secondly to be understood that the manufacturing technology and products. At the same time, it is necessary to combine the process requirements in flow measurement, especially when the measurement or control requires high accuracy, the scale display is intuitive, and the viscosity of the medium is high, the media flow can be directly displayed with density and viscosity compensation performance. Metal tube rotor flowmeter . Master accurate process conditions and provide very accurate media parameters. Because the scale conversion and verification is done according to the media condition. Select the appropriate measuring part material.
Generally choose the material with good corrosion resistance. Only by ensuring that the float and the measuring components are not corroded by the medium for a long time, can they ensure the long-term precision of the product when shipped from the factory. Use a range of full scale that allows the normal operating flow to be in the range of 50% to 80%. The normal working flow is less than 50% of the range, so that the absolute error at the measuring point increases, which is not conducive to control accuracy.
This is especially important for manufacturing companies that have density and viscosity correction capabilities. Because the difference in density or viscosity will directly affect the calibration of the flow calibration. For flowmeters that directly display the scale of water or air flow under the calibration conditions, manufacturers may be required to provide calibration data and flowmeter certificates. When the instruments are actually used, the density must be manually calculated based on these calibration data and calculations. Corrected. The correction method may be a chart method, a table method, or a coefficient correction method on a flow computer or a DCS. Ensure the correct installation of the instrument. The verticality is mainly a point that is often overlooked when installing a metal tube rotor flowmeter . Under normal circumstances, the verticality must be within 2 degrees. For metal tube rotameters that require control functions, products with communication capabilities should be used as far as possible. When the media condition changes, the communication function of the product can be utilized to adjust the signal on site to ensure the product accuracy to the maximum extent. Conditional users may re-inspect the instrument according to the flow calculations and calibration records provided by the flow meter manufacturing enterprise.
Periodic verification ensures the accuracy of accuracy. To ensure the long-term measurement accuracy of metal tube rotor flowmeters , the cycle is an indispensable means of verifying the product. Under normal conditions, the verification of metal tube rotameters is usually performed using direct water or air. There are two aspects to note: if the media condition on the meter scale is the same as the media condition at the time of verification, the flow rate comparison can be used to calculate the accuracy; if the media conditions of the two are different, it is necessary to understand the Does the product have density and viscosity correction? If there is no function to be corrected, it is also necessary to understand the condition of the scale change or the calculation formula. According to the corresponding formula, the coefficient calculation can be performed. If you have a density and viscosity correction function, you should ask the manufacturer to provide a calculation method or calculation result. Use the correct calculation results to verify the product.
