noun
- a flow meter that measures the flow rate of liquid or gas in a closed tube by the position of a float that rises with increased flow
Usage: technical; engineering
Examples
- The technician calibrated the rotameter to ensure accurate gas flow measurements.
- A rotameter uses a tapered tube and a float to indicate flow rate.
- The laboratory equipment included several rotameters for monitoring different chemical processes.
- Engineers installed rotameters throughout the pipeline system to track fluid flow.
- The rotameter’s float position directly corresponds to the volumetric flow rate.
- Quality control requires regular inspection of each rotameter in the facility.
