digital metal tube rotameter

The metal tube rotameter adopts the principle of variable area measurement. The measuring component is composed of a conical measuring tube and a float. The float can move up and down freely in the conical measuring tube, changing the flow area in the pipeline, and with the change of the flow rate , the vertical position of the float in the measuring tube also changes accordingly, and the position of the float is transmitted to the dial of the indicator through the magnetic transmission system, so as to indicate the size of the flow value.

The metal tube float flow meter adopts the variable area measurement principle and is suitable for measuring the flow of various liquids and gases. The flowmeter adopts an all-metal structure, and includes on-site indication type, data remote transmission type, corrosion-resistant type, high temperature and high pressure type, jacket type, and explosion-proof type. It has 0-10mA, 4-20mA standard analog signal output and on-site indication, cumulative digital communication, on-site modification of measurement parameters, different power supply methods, and can be equipped with magnetic filters and special specifications. It is widely used in the measurement and control of various media in complex and harsh environments such as petroleum, chemical, power generation, pharmaceuticals, food, and water treatment.

The metal rotor flowmeter has the characteristics of simple structure, reliable operation, wide application range, accurate measurement and convenient installation. Install a magnetic filter at the entrance. Its material should be the same as the corresponding flowmeter. Metal tube rotameter has been widely used in petrochemical, steel, electric power, metallurgy, light industry, food, pharmaceutical, water treatment and other industries due to its excellent performance and reliability, as well as good performance-price ratio.

The intelligent metal tube float flow meter is a variable area flow meter based on the float position measurement. It adopts all-metal structure, has the characteristics of small size, small pressure loss, large range ratio (10~20:1), optional transmitter with HART communication function, convenient installation and maintenance, etc. It is widely used in complex and harsh environments in various industries. It is suitable for flow measurement and process control of small flow, low flow rate, and various harsh media 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.

Variable area flow meter Series are used for measure instantaneous and accumulated flow rate of liquid, gas and steam in closed pipelines. It is suitable for metering flow value on site or electronic remote. The measuring principle is based on the hydrodynamic effects,This makes float moving from bottom to top in vertical Pipe. As the displacement of float is in related to flow rate, which can be read from the indicator by means of the magnetic drive system in non-contact form . Also, flowmeters output electrical signal (4-20)mA / hart communication protocol with high / low limit Warning switches/integrating flow PCB broad can be configured.

metal tube rotameter is suitable for small flow ranges with high accuracy. Its display can be a mechanical pointer or LCD digital
display. If digital metal tube rotameter, it can send 4-20ma output and have RS 485. It can also be equipped with a limit switch and alarm.
BCST metal tube rotameter consists of a tapered tube, inner float, and display part. Each part is made by ourselves, from electric board to
float, so the delivery time is fast, there is enough raw material in stock. Usually, it is 3-4 working days for standard products.

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.

The Metal Tube Rotameter uses the variable area measurement principle. The intelligent metal tube float flowmeter has a local display type and an intelligent remote transmission type, with the transmitter. Metal Tube Rotameter can be used to measure the flow of liquid, gas, and steam. It is especially suitable for medium flow measurement with a low flow rate and small flow.

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.
