A metallic tube variable area flowmeter is a simple device that measures the volumetric flow rate of gases or liquids. It consists of a tapered metal tube with a float attached at the end. The information about flow rate is transmitted to a scale by a magnetic coupling system. This flowmeter is widely used in the chemical plant, power station, and petroleum industries. Its flexibility, reliability, and economical design make it the ideal choice for a wide range of applications.

A metallic tube variable area flowmeter can be used in harsh environments and aggressive media. It can be ATEX-certified and is suitable for applications in potentially explosive atmospheres. Its high precision and easy reading make it suitable for a wide range of applications. These meters are also widely used in the chemical, food, and petrol industries.

Another type of variable area flowmeter is the tapered plug type. The core of this device remains stationary while the piston moves, thereby adjusting the external flow rate indicator. There are two types of metallic tube variable area flowmeters: the one with a metallic body and the other with a tapered plug.

A metallic tube variable area flowmeter is often referred to as a rotameter. These flowmeters are made of glass or stainless steel and are capable of measuring very low flows. Some models are capable of measuring as low as 0.05 cc/min for liquids and 0.5 cc/min for gases. The most common glass tube rotameters are equipped with a 1/4-in (6-mm) connection and can handle 0.5-0.5 gpm of water or 0.2-2.0 scfm of air. Their accuracy is up to 5% over the 10:1 range.

A metallic tube variable area flowmeter is suitable for many applications. Its low-flux density reduces the accumulation of magnetic particles that can cause indicator errors. Its scrubbing system also prevents the need for extensions of the float, a common cause of damage when removing meters.
