What are the Common Methods of Gas Flow Measurement?
Several techniques are employed to measure gas flow rates, each with its own advantages and limitations. The most common methods include:
- Thermal Mass Flow Meters: These devices measure the heat transfer from a heated element to the gas flow. They are highly accurate and suitable for low flow rates. - Coriolis Flow Meters: These meters measure the mass flow rate based on the Coriolis effect. They are known for their high precision and ability to measure a wide range of flow rates. - Rotameters: These are simple and cost-effective devices that measure flow rate based on the float's position in a tapered tube. They are ideal for visual monitoring. - Ultrasonic Flow Meters: These meters use ultrasonic waves to measure the flow rate. They are non-intrusive and suitable for various gas types.
