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.

Metal tube rotameters consist of a measuring tube and a local indicator. The local indicator can also optionally be fitted with additional electrical components, suitable for the measurement of liquids and gases. Using the principle of variable area measurement, the measuring part is composed of a conical measuring tube and a float. The float can move up and down freely in the conical measuring tube to change the flow area in the pipeline. The vertical position in the pipe also changes accordingly, and the position of the float is transmitted to the dial of the indicator through the magnetic transmission system through the steel pipe, indicating the size of the flow value.

The float of the metal rotameter is in the measuring tube. With the change of flow, the float moves up, 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 rising position of the float in the measuring tube represents the flow rate, and the position of the changing float is transmitted by the internal magnet to the external indicator, so that the indicator can correctly indicate the flow value at this time. . This makes the indicator housing not in direct contact with the measuring tube, so even if a limit switch or transmitter is installed, the instrument can be used under high temperature and high pressure working conditions. It is a variable area flow measuring instrument commonly used in industrial automation process control. It has the characteristics of small size, large detection range and convenient use. It can be used to measure the flow of liquid, gas and steam, especially suitable for medium flow measurement with low flow rate and small flow.

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.

troleum, chemical, power generation, pharma-
ceutical, food, water treatment, etc. Complex,
