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.

A rotameter is an industrial flowmeter used to measure the flowrate of liquids and gases. The rotameter consists of a tube and float. The float response to flowrate changes is linear, and a 10-to-1 flow range or turndown is standard. In the case of OMEGA? laboratory rotameters, far greater flexability is possible through the use of correlation equations. The rotameter is popular because it has a linear scale, a relatively long measurement range, and low pressure drop. It is simple to install and maintain.

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. 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

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.

It operates on the principle of variable area; the fluid in the metal tube raised a float in the taper tube increasing the area of passage of fluid. The float moves up in proportion to the rate of flow of fluid and get stabilized when the weight of the float is balanced by the upward hydraulic force. By a magnetic coupling the inner float movement through a series of linkages and counter weight. The tube and the float combination determine the flow rate. The inner float magnetic field is detected by the high sensitive magnetic field detection sensor, enable us to show the digital readout.As such this flow meter does not require any electrical connection, since it operates on battery. It has an inbuilt two wire transmitter provide 24 VDC and take 4 – 20 mA signal.

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.
