The float of the metal tube float flowmeter moves the float upward with the change of the flow rate in the measuring tube, and the buoyancy of the float and the gravity of the float reach a balance at a certain position. At this time, the flow annulus area between the float and the orifice plate (or cone tube) remains constant. The area of the annular gap is proportional to the rising height of the float, that is, the float is in the measuring tube, the rising position represents the flow rate, and the changing position of the float is transmitted by the internal magnet to the external indicator, so that the indicator can correctly indicate the flow at this time. value.

vertical installation of the measuring tube. The displacement of the float
is proportional to the size of the flow. Through the magnetic drive system,
the float displacement is transferred to the indicator directly indicating the
size of the flow in a non-contact manner. It can also offer 4-20 mA, HART,
low and high alarm with an extra flow PCB installed.

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.
