How to install the rotameter

Abstract: The information on the installation method of the rotor flowmeter is provided by the excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Rotameters are generally divided into glass rotameters and metal tube rotameters. Generally, they can operate normally for a long time without maintenance after installation. Therefore, the installation of rotameters also needs to be paid attention to. Measure cooling. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the installation method of the rotor flowmeter. Rotameters are generally divided into glass rotameters and metal tube rotameters. Generally, they can operate normally for a long time without maintenance after installation. Therefore, the installation of rotameters also needs to be paid attention to. To measure liquids that are easy to precipitate crystallization or solidify when cooled, a metal tube rotameter with a jacket should be used. Precautions for installation and use of rotameter: 1. In the installation direction of the instrument, most rotameters must be installed vertically on a pipeline without vibration, and there should be no obvious inclination, and the fluid flows through the instrument from bottom to top. The instrument does not have strict requirements on the length of the upstream straight pipe section, but there are also manufacturers that require (2-5)D length. 2. For the installation of dirty fluid, a filter should be installed upstream of the instrument. When the metal tube rotameter with magnetic coupling is used for fluids that may contain magnetic impurities, a magnetic filter should be installed in front of the meter. To keep the float and conical tube clean, especially for small-diameter instruments, the cleanliness of the float obviously affects the measured value. 3. The flow value of the rotameter should be converted as necessary. If it is not an instrument specially ordered by the rotameter manufacturer according to the medium parameters such as density and viscosity, the flow rate of the liquid meter is usually calibrated with water, and the gas meter is calibrated with air. Engineering Standard Status. When the fluid density, gas pressure and temperature of the operating conditions are inconsistent with the calibration, necessary conversions must be made. Conversion formulas and methods are detailed in the manufacturer's instruction manual for the rotameter. The main measurement object of the rotameter is single-phase liquid or gas, which is usually not applicable if the liquid contains particulate solids or the gas contains droplets. Because the float adheres to particles or tiny air bubbles in the liquid flow, it will affect the measurement value. If it is necessary to transmit a signal far away for total accumulation or flow control, a metal tube rotameter (ie, a metal tube rotameter) with electrical signal output is generally used. If the ambient atmosphere has explosion-proof requirements and there is a gas source for the control instrument on site, the remote metal tube rotameter is given priority. In short, the selection of different types of flowmeters is particularly important for different use environments and use requirements. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Installation method of rotor flow meter'
