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.
