Description
Turbine Flow Meters
Turbine flow meters are accurate, cost-effective instruments that measure flow by detecting the rotational speed of a turbine rotor placed directly in the fluid stream.
How They Work
Fluid flow spins a multi-bladed turbine rotor. The rotational speed is directly proportional to the flow velocity. Sensors (usually magnetic) detect the spinning blades and convert the movement into an electrical pulse signal, which is then processed to calculate the flow rate.
Advantages
- High accuracy and excellent repeatability
- Wide flow range with good turndown ratio
- Low pressure drop
- Compact, lightweight, and easy to install
- Cost-effective for clean fluids
- Ideal for custody transfer when properly calibrated
Limitations
- Best suited for clean, low-viscosity fluids
- Not recommended for dirty or abrasive fluids
- Bearings can wear over time
- Requires straight pipe runs for best accuracy
- Performance drops at very low flow rates
Typical Applications
Turbine flow meters are widely used for measuring hydrocarbons, water, chemicals, cryogenic liquids, air, and industrial gases in water distribution, petroleum custody transfer, HVAC systems, and general process control.
If a turbine flow meter doesn’t perfectly fit your needs, we also offer Ultrasonic, Coriolis, Vortex, and Electromagnetic flow meters.
