Cost-effective, widely favored by petrochemical, steel, metallurgical light industry, food, pharmaceutical, water treatment and other industries.

The tube rotameter is a variable area flow measuring instrument, which consists of a measuring tube, a float, an indicator, and a process connection. For continuous measurement of volumetric flow of liquids and gases in closed pipes. The metal tube rotameter has the characteristics of firm and reliable structure, wide temperature range, high precision, low price, and can be used for flow measurement in various occasions. This series is an on-site intelligent indication type, and a remote signal transmission type is optional. There are three installation forms: bottom in, top out, left in and right out, and bottom in and side out. It is widely used in liquid and gas flow measurement in chemical, petroleum, metallurgy, electric power, environmental protection, medicine and light industry sectors

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 metal tube rotameter is a variable area flow meter based on the float position measurement, which is especially suitable for the measurement of gas and liquid flow with low flow rate and small flow. The metal tube float adopts an all-metal structure and a Modular concept design. It has the characteristics of small volume, small pressure loss, large range ratio, and convenient installation and maintenance. Therefore, it is widely used in complex and harsh environments in various industries. Flow measurement and process control for harsh media conditions.

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 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.

The remote type metal tube rotameter can be used in flow measurement and process control in complex, harsh environments and various medium conditions, and is suitable for measuring liquids and gases. Especially suitable for small diameter and low flow rate medium flow measurement; widely used in: chemical industry, power generation, food, water treatment, etc. In the process of flow measurement in complex, harsh environmental conditions, and various medium conditions.

The metal rotor flowmeter gives full play to its advantages in the measurement of medium flow with small diameter and low flow rate. Its simple structure, reliable operation, wide application range, accurate measurement and convenient installation are its outstanding features. Widely used in chemical and food and pharmaceutical industries.
Metal rotameter has common type and anti-corrosion type. The above two types are divided into on-site indication type and electric remote transmission type. The instrument material is (1Cr18Ni9Ti), and the anti-corrosion type is (1Cr18Ni9Ti) lined with PTEF. If the measured medium is easy to crystallize or freeze, the metal tube rotor flowmeter with steam trace heating can also be used. If the measured medium contains magnetic objects, a magnetic filter can be installed at the inlet of the flowmeter. The corresponding flow meters are the same.

It can be used to detect the flow of various liquids and gases, especially for the measurement of medium flow with low flow rate and small flow. Scope of application: Metal tube rotameter is suitable for small diameter and low flow rate Medium flow measurement; reliable work, low maintenance, long life, low requirements for straight pipe sections; widely used in petrochemical, steel, electric power, metallurgy, light industry and other industries

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.

Metal Tube Rotameter is a flow meter measuring the instantaneous and
cumulative flow of fluid (liquid, gas and steam) through a closed pipe.
It uses the dynamic action of the fluid to make the float move up in the
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.

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.

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 rotameter has local indication type and smart remote type with a pointer LCD displaying instantaneous/ accumulated flow rate, upper-limit, and lower-limit alarm output, accumulative pulse output, batch control, standard two-wire 4-20mA current output, etc.
Additionally, this instrument employs advanced microprocessing central chip and high-quality
industrialized components of Motorola corporation to ensure the good performances of flowmeters in all applicational fields.
For many years metal tube rotameter are well received by many industries such as
petrochemical, steel, and iron, electric power, metallurgy, light industry, food, pharmacy, and
