Metal Tube Rotameter
Product Overview
Section titled “Product Overview”The Metal Tube Rotameter is a variable-area flowmeter for liquid and gas flow measurement. It consists of a measuring tube, float, indicator and process connections. As the medium flows upward through the measuring tube, it lifts the float. The balanced float position corresponds to flow rate and is transmitted to the indicator by magnetic coupling or mechanical structure.
This type of flowmeter is robust and suitable for small and medium flow measurement, higher temperature or pressure conditions, local indication and remote transmission. According to the catalogue, optional configurations include magnetic filter, damping device, electrical signal output, intrinsic safety system and upper/lower limit alarm switches.
Applications
Section titled “Applications”- Local flow indication and process monitoring for liquids and gases.
- Chemical, petroleum, metallurgy, power, pharmaceutical and environmental protection applications.
- Measuring points requiring mechanical indication, transmitter output or alarm switches.
- Industrial sites where glass tube rotameters are not suitable due to pressure, temperature or environment.
