The flow measurement of the metal rotameter is performed by the transmitter in the indicator by coupling the porcelain steel to feel the change of the float position to complete the flow indication and the remote transmission of the signal. When the measured medium flows through the measuring tube from bottom to top, when the float is balanced by gravity, buoyancy and the vertical upward driving force of the fluid velocity on the float, the float is relatively stationary at a certain position, and this position varies with the distance between the float and the vertebral canal. The ring area and fluid velocity vary, and the position of the float corresponds to the flow rate of the measured medium.

rotameters measure flow rate of a liquid or gas by relating linear displacement of an internal ¡°float¡± or sharp-edged orifice tube to a corresponding flow rate. Variable Area meters either allow flow through a peripheral orifice formed between a tapered wall and a float as in the traditional rotameter, or an annular orifice and an internal tapered metering pin in the Device Head. The attributes of the Variable Area flow meter are a linear relationship between flow rate, pressure differential and piston displacement. Flow rate is read on the Variable Area meters in both Analog or Digital Display by aligning the position of the piston/float to an adjacent calibrated scale.
