Frequently Asked Questions (FAQs)

What is a metal tube rotameter and how does it work?

?

A metal tube rotameter is a type of variable area flow meter that measures the flow rate of liquids, gases, or steam. It consists of a tapered metal tube and a float that rises as fluid flows through the tube, indicating the flow rate on a calibrated scale. The float’s position is determined by the balance between the upward force from the fluid flow and the downward gravitational force, making it a simple yet effective tool for flow measurement.

What are the key applications of metal tube rotameters in various industries?

?

Metal tube rotameters are widely used in several industries due to their versatility and reliability. You can find them in petrochemical engineering, iron and steel production, electric power plants, metallurgy, food processing, pharmaceuticals, water treatment, and more. They are particularly useful for measuring low flow speeds and small flow rates, making them essential in complex and harsh environments.

How do I ensure the correct installation of a metal tube rotameter?

?

To ensure the correct installation of a metal tube rotameter, you need to follow a few key steps. First, the rotameter must be installed vertically, with the fluid flowing from the bottom to the top. The inlet and outlet connections should be secure, and the device should be level to avoid any inaccuracies in measurement. Proper installation is crucial for accurate readings and the longevity of the device.

What are the technical specifications and accuracy of metal tube rotameters?

?

Metal tube rotameters come with various technical specifications depending on the model. Generally, they offer an accuracy of ±2.5% for normal types and ±1.5% for high-accuracy types. They can operate in a wide range of temperatures (-25°C to +300°C) and pressures (up to 4.0 MPa). The flow range ratio is typically 10:1, and they can be powered by DC or battery power. These specifications make them suitable for a broad range of industrial applications.

How do metal tube rotameters handle high temperatures, corrosive media, and explosive environments?

?

Metal tube rotameters are designed to handle challenging conditions. They can be made from high-temperature and corrosion-resistant materials such as stainless steel or PTFE, ensuring long-term stable operation in harsh environments. Additionally, many models are explosion-proof and intrinsically safe, marked with certifications like Exia II CT1~T6, making them suitable for use in inflammable and explosive settings. This robust design ensures reliability and safety in demanding industrial scenarios.
