Frequently Asked Questions

What are the different types of flow meters?

Flow meters come in various types, including:

• Positive Displacement Flow Meters: Measure the actual flow of liquid by dividing the fluid into fixed, incremental volumes.

• Magnetic Flow Meters: Use a magnetic field to detect the flow of conductive liquids.

• Ultrasonic Flow Meters: Employ ultrasonic waves to measure flow velocity and rate without direct contact with the fluid.

• Turbine Flow Meters: Measure flow by detecting the rotational speed of a turbine placed in the fluid stream.

How do flow meters work?

Flow meters operate based on different principles:

• Positive Displacement: Fluid moves mechanical components that divide the flow into fixed volumes.

• Electromagnetic: Fluid passing through a magnetic field induces a voltage proportional to its velocity.

• Ultrasonic: Sound waves travel at different speeds depending on the flow direction, allowing for flow measurement.

• Turbine: Fluid flow causes a turbine to rotate, with speed proportional to flow rate.
