BGN Full Metal Rotameter

Full metal variable area flow meter-BGN with Datasheet

Kobold BGN is suitable for flow measurement of liquid or gaseous products in pipes. It shows current flow rate in volume or mass per unit in time. The fluids will flow through from bottom to top through the BGN flow meter tube.

The meter’s design makes it ideal for processes under difficult and rough operating conditions. Flow measuring, dosing, monitoring, adjusting and control of liquid and gaseous products. The devices are available with additional electrical equipment for process monitoring and control.
