Metal Tube Rotameter – Description

A Metal Tube Rotameter is a variable-area flow meter used to measure the flow rate of liquids, gases, and steam in industrial processes. It consists of a metal tapered tube containing a float that moves vertically according to the flow rate.

Working Principle:

• Fluid enters the bottom of the meter and flows upward through the tapered tube.
• The flow lifts the float until the upward force of the fluid equals the downward force of gravity.
• The float position corresponds to the flow rate and is indicated mechanically or electronically.

Advantages:

• Suitable for harsh industrial environments
• Handles high pressure and temperature conditions
• Low maintenance and long service life
• Can measure both liquid and gas flow accurately.
