How to install Huaian Runtai rotameter meter

Abstract: The information on how to install Huaian Runtai rotameter meter is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. The main measurement object of the rotameter is a single-phase liquid or gas, and the liquid containing particulate solids or the gas containing droplets is usually not applicable. Because the float adheres to particles or tiny air bubbles in the liquid flow, it will affect the measurement value. If you need to transmit the signal far away for the total amount. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the article details on how to install Huaian Runtai rotor flowmeters. The main measurement object of the rotameter is a single-phase liquid or gas, and the liquid containing particulate solids or the gas containing droplets is usually not applicable. 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 an air source for the control instrument on site, the remote metal rotameter is given priority. If the electric remote transmission instrument is selected, it must be an explosion-proof type. When measuring high-viscosity liquids with a temperature higher than the ambient temperature and liquids that are easy to crystallize or solidify when cooled, a metal tube rotor flowmeter 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 angle between the center line of the rotor flowmeter and the vertical line is generally not more than 5 degrees, and the high-precision (above 1.5) instrumentθ≤20°. ifθ=12°An additional error of 1% will occur. 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, which is actually not necessary. 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 pulsation of the pulsating flow of the rotor flowmeter itself, if there is a reciprocating pump or regulating valve upstream of the location where the instrument is to be installed, or there is a large load change downstream, etc., the measurement location should be changed or the pipeline system should be remedied and improved, such as adding Install a buffer tank; if the instrument itself oscillates, such as the gas pressure is too low during measurement, the upstream valve of the instrument is not fully opened, the regulating valve is not installed downstream of the instrument, etc., it should be improved and overcome, or an instrument with a damping device should be used instead. 4. 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 above is the whole content of this article.
