All-Metal Variable Area Flow Meter
Type: BGN
The BGN meter is suitable for flow measurement of liquid or gaseous products and steam in pipes.
Indication of momentary volume- or mass flow per time unit.
Due to its rugged design it is suitable for processes under difficult and harsh conditions.
For process monitoring and regulation, the units are available with additional electrical equipment.

Applications
Flow measurement of liquid or gaseous products and steam in pipes. Indication of momentary volume- or mass flow per time unit. The areas of application include a variety of:
- In the chemical and petrochemical industry: Using an all-metal construction is advantageous in environments where corrosion is a concern. Chemical processes in the industry may involve corrosive substances that could degrade non-metallic materials. In the petrochemical industry, processes often involve high temperatures. Metal flow meters can withstand elevated temperatures better than some non-metallic alternatives.
- The oil and gas industry involves harsh environments with varying temperatures, pressures, and often corrosive substances. An all-metal construction enhances the durability and resilience of the flow meter, allowing it to withstand these challenging conditions. Oil and gas processes may involve corrosive substances. The corrosion-resistant properties of metal flow meters make them suitable for use in environments where corrosion is a concern.
- In food processing, hygiene is of utmost importance. An all-metal construction can be advantageous as it is often easier to clean and sterilize than meters with non-metal components. Metal flow meters generally exhibit good stability at a wide range of temperatures. This is important in food processing where temperature variations can occur during different stages of production.
- Pharmaceuticals may include corrosive substances, and the use of an all-metal flow meter ensures corrosion resistance, maintaining the integrity of the meter over time. Variable area flow meters provide visual flow rate indications and, when constructed with metal components, can offer high accuracy and precision in measuring fluid flows.
