Mass flow meter installation details

Mass flowmeter installation details The mass flowmeter is an instrument with accurate medium flow detection and low installation requirements in the existing industrial production. Because it can directly detect the quality, density and temperature of the medium flowing through the internal measuring tube of the instrument, it is very important for the flow of the medium. The state does not have strict laminar flow requirements, so there is no straight pipe section requirement for the pipeline before and after the flowmeter during the installation process, and it can be installed arbitrarily like a regulating valve, which greatly facilitates the construction and installation on site. Mass flowmeters have various shapes: mass flowmeters have various shapes, but their internal structures are almost the same. Basically, they are composed of two U-shaped measuring tubes. Three coils are installed on the bottom between the two measuring tubes and on the left and right sides. The coil is the excitation coil, and the left and right coils measure the mass and the density. In addition, a thermal resistance is buried inside the measuring tube to detect the temperature of the medium. Details of the installation process Since the mass flowmeter can detect the density of the medium in real time without artificially setting a constant density of the medium, the detection value of the mass flowmeter is accurate and reliable, and the construction and installation are simple and convenient. Although the mass flowmeter has no requirements for the front and rear pipelines of the flowmeter during construction and installation, some details should also be paid attention to during the installation process: it is necessary to ensure that the front and rear process flanges of the flowmeter are welded concentrically, which can eliminate the difference between the flanges during the installation process. The additional torque caused by the center can reduce the use error of the mass flowmeter; also pay attention to some supporting construction processes, especially the influence of the eccentric torque and additional stress on the operation of the flowmeter during the heating line laying process; although the mass flowmeter measures The tube is inside the shell, but the external stress can still produce unmeasurable additional errors in the detection, such as the fixed iron wire of the heating line in the figure, which is deformed due to the influence of temperature during operation and causes a randomly changing stress superposition; The laying should also have a certain distance from the mass flowmeter to prevent the asymmetric stress generated by the thermal expansion of the heating line and the influence of excessive heat conduction on the temperature detection of the mass flowmeter medium.
