Rotameter
A rotameter is a device that measures the volumetric flow rate of fluid in a closed tube. It
belongs to a class of meters called variable-area flowmeters, which measure flow rate by
allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect.
Features
- Rangeability is better.
- It is easily equipped with alarms and switches or any transmitting devices.
- It also measures the flow rate of corrosive fluids.
- There is an availability of viscosity-immune floats.
