All-Metal Variable Area Flow Meter
Type: BGF

The BGF 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.

Especially suitable for its robust design for processes under difficult and harsh conditions. Any flow direction offers extended application opportunities.

For process monitoring and regulation, the units are available with additional electrical equipment.
