Principle structure

As the fluid upward in the tube, the float moves upward to a certain positon where the lifting force and the gravitational force Are balanced, at the moment, the circulation area between the float and the orifice is kept fixed.The circulation area is Proportinal to the height of the float, it means the height of the float represent the volumetric flowrate. When the float

Moves up and down, it transmits its positional to the indicator outside in form of magnetic-coupling, so make the needle of the Indicator follows the movement of the float, and by using the cam board to show the value of flowrate linearly on the indicator

Main components

Tapered Tube

The metal tube is tapered, meaning it gradually widens from bottom to top.This shape allows the float to stabilize at different levels based on the flow rate, as the increased area at the top fits higher flow rates.

Float

The float is often made of a corrosion-resistant material like stainless steel. It's carefully designed to offer stable equilibrium within the tube, moving up and down freely in response to changes in flow rate.

Magnetic Coupling

Many metal tube rotameters use a magnetic coupling to transmit the float position to an external indicator, eliminating the need for a transparent tube.

Indicator Mechanism

The external scale or indicator provides the flow reading. It can be analog or digital, depending on the specific rotameter model.

Applications

Oil & gas industry

In oil and gas refineries, metallic tube variable-area flowmeters monitor the flow of crude oil, natural gas, and other hydrocarbons.their power to handle high pressures makes them suitable for pipelines and wellheads.

Chemical processing

Metallic tube variable-area flowmeters, resistant to corrosion and capable of withstanding challenging conditions, are frequently used to monitor the flow of chemicals and process liquids.

Waste water treatment

Metallic tube variable-area flowmeters are used in wastewater treatment facilities to measure the flow of water and chemicals for disinfection and ph adjustment processes.

Pharmaceutical industry

In controlled environments, metallic tube variable-area flowmeters help monitor the flow of solvents, water, and other process fluids essential to pharmaceutical production.

FAQ

Q: Are you a manufacturer or a trading company?

A: We are a leading manufacturer of all pneumatic products. Welcome to visit our factory at any time.

Q: What's the payment term?

A: T/T, MasterCard, VISA, E-Checking, Boleto, Pay Later.

Q: How about the delivery time ?

A: 1-3 days for normal models. For big orders, it takes about 10-15 days.

Q: What is the standard of package?

A: Export standard package or special package according to customers' requirement.

Q: What kind of product quality does your factory offer?

A: We are top 3 supplier in Chinese market. We offer top quality to our clients.

Q: What is the principle of metal tube flow meter?

A: Metal tube rotameters work based on the principle of variable area. It consists of a tapered tube, typically made of steel with a float. The fluid in the metal tube raises the float in the tapered tube increasing the area of passage of fluid.

Q: What is the difference between metal tube and glass tube rotameter?

A: Unlike glass tube rotameters, which are more common for lower pressures and clear visibility, metal tube rotameters are typically used in environments where the fluid is turbid, high-pressure, or chemically reactive.

Q: What is the rule of thumb for flow meter installation?

A: Note the intended direction of the flow as indicated by an arrow on top of the Flow Meter. There must be free, unrestricted pipe of the same size as the Flow Meter, with a length of at least 10 times the flow meter size upstream, and 5 times the flow meter size downstream of the Flow Meter tee.

Q: What is the minimum flow rate for a magnetic flow meter?

A: The electromagnetic flow meter can be used for continuous measurement or for batching and dosing applications. The MAG-VIEW™ series operates on the magnetic inductive principle and is therefore suitable for electrically water and conductive liquids with a minimum conductivity of 20 or 50 μS/cm.
