A fuel flow meter measures the volume or mass of fuel passing through a system over time.
Understanding Turbine Fuel Flow Meters
One common type of fuel flow meter is the turbine fuel flow meter. This device operates based on the principle of converting the movement of a rotating element into a measurable signal representing the fuel's flow rate.
The core mechanism involves a turbine rotor positioned within the path of the fuel flow.
How a Turbine Fuel Flow Meter Operates
Based on the provided information, the operation of a turbine fuel flow meter can be described in simple steps:
- As the fuel (fluid) flows through the meter, it impacts upon the turbine blades.
- This impact causes the rotor to be set in motion, spinning around an axis.
- The rotor's speed increases until a steady rotation speed is reached.
- Crucially, when steady, this rotation speed is proportional to the fluid's velocity. The faster the fuel flows, the faster the turbine spins.
- The meter then converts the mechanical action of the turbine rotating... into a flow rate. This conversion typically involves sensing the rotor's speed (e.g., using a magnetic pickup that counts blade passes) and translating that into a volume or mass per unit time measurement.
In essence, a turbine fuel flow meter converts the mechanical action of the turbine rotating in the fluid around an axis into a flow rate. The faster the turbine spins, the higher the calculated flow rate of the fuel.
