The structure of the metal rotor flowmeter determines the installation direction

Most of the metal rotor flowmeters we see are installed vertically on vibration-free pipes, and the flow direction is from bottom to top. So is this determined by the structural diagram of the metal rotor flowmeter? Are there horizontally installed metal rotor flowmeters?

Generally speaking, the metal rotameter needs to be installed vertically upward because it has a tapered tube inside and a float that can move up and down in it. When the fluid passes through the tapered tube from top to bottom, the float is affected by the force of the fluid and moves upward along the tapered tube. The greater the flow, the greater the displacement of the float, which determines the size of the annular area between the float and the tapered tube. The instantaneous flow rate through the annular area at this time can be calculated through the formula.

So to a certain extent it can be said that the structural diagram of the metal rotor flowmeter determines the installation direction. However, with the development of technology, there are now horizontally installed metal rotameters, such as the DQR series metal rotameter of Supmea Flow, which can not only measure the medium flow of horizontal flow, but also realize bottom inlet and side outlet, side inlet and top outlet. Flow measurement in equal flow directions.
