The advantage of Variable Area Flow Meter
- Variable area flowmeters requires no external power or fuel, it uses only the inherent properties of the fluid, along with gravity, to measure flow rate.
- Since the area of the flow passage increases as the float moves up the tube, the scale is approximately linear.
- Clear glass is used which is highly resistant to thermal shock and chemical action.
