Rotor flowmeters are generally divided into glass rotor flowmeters and metal tube float flowmeters. Generally, they can operate normally for a long period of time without maintenance after installation. Therefore, the installation of the rotor flowmeter needs to be paid attention to.

For measuring liquids that are easy to precipitate crystals or are easy to solidify, a jacketed metal tube rotor flowmeter should be used. Rotor flowmeter installation and use precautions:
1. Instrument installation direction Most rotor flowmeters must be installed vertically on a non-vibrating pipe. There should be no obvious inclination, and the fluid flows through the instrument from bottom to top. The meter does not have strict upstream pipe length requirements, but there are also manufacturers required (2-5) D length.
2. For the installation of dirty fluids, the filter should be installed upstream of the instrument. A metal tube rotameter with magnetic coupling for magnetic fluids that may contain magnetic impurities should be fitted with a magnetic filter in front of the instrument. To keep the float and the cone clean, especially for small-diameter instruments, the cleanliness of the float significantly affects the measured value.
3. The flow value of the rotameter should be converted. If it is not according to the medium parameters such as density and viscosity, the instrument for liquid flow meter is usually calibrated with water. The gas meter is calibrated with air. Engineering standard status. When the fluid density and gas pressure temperature of the use conditions are inconsistent with the calibration, the necessary conversion is required. Conversion formulas and methods Rotor flowmeters are detailed in the manufacturer's instructions.
Rotor flowmeters mainly measure single-phase liquids or gases, and liquids containing particulate solids or gas containing droplets are generally not suitable. Because the float attaches particles or tiny bubbles in the flow, it will affect the measured value. If it is necessary to transmit signals for total accumulation or flow control, a metal tube rotor flow meter (ie, a metal tube float flow meter) for electrical signal output is generally selected. If the ambient atmosphere has explosion-proof requirements and the site has a gas source for controlling the instrument, the remote metal tube rotor flowmeter is given priority. In short, the selection of different types of flowmeters for different use environments and usage requirements is particularly important.
