Turbine flow meters operate by using a rotor that spins as fluid flows through it. The speed of the rotor correlates to the flow rate. They are commonly used in industrial machinery and lubrication systems due to their high accuracy and ability to handle a wide range of flow rates. Brands like Badger Meter offer reliable turbine flow meters that excel in performance.
2. Gear Flow Meters
Gear flow meters consist of two or more rotating gears that trap fluid in their teeth and measure the flow rate based on the number of rotations. They are compact and are often used in oil and fuel applications. Their high precision makes them a popular choice for applications requiring accurate flow measurement.
3. Electromagnetic Flow Meters
Electromagnetic flow meters use Faraday’s law of electromagnetic induction to measure fluid flow. They are particularly beneficial for applications involving corrosive fluids, as they have no moving parts. This technology is widely used in water and wastewater treatment facilities, making them a reliable choice for such environments.
4. Ultrasonic Flow Meters
Ultrasonic flow meters measure flow by sending ultrasonic waves through the fluid. They can be non-intrusive, making them suitable for applications in HVAC systems and irrigation. Their ability to measure flow in large pipes without any physical connection to the fluid makes them a versatile option.
5. Mechanical Flow Meters
Mechanical flow meters are traditional devices that rely on mechanical components to measure flow. They are commonly found in mobile machinery and agricultural equipment. Their simple design and ease of maintenance make them a favored choice for various applications.
