Inside the flow tube, there is a star guided float which works
towards a spring. An annular gap is produced between the
cone-shaped magnet system and the meter ring in case of
flows other than zero. The position of the magnet system
depends on the resulting force of all forces acting upon it.
These forces comprise the flow force, a spring force acting
opposite to the flow force, and the buoyancy and weight
force significant for the measurements in case of vertical
installation. Each position of the magnet holder corresponds to
a flow value measured during calibration, which is transferred
to a scale. The BGF flow meter consists of a meter tube with
connections, a meter ring, and a conical magnet holder. By
means of a magnet, the position of the magnet system is
transferred to an encapsulated follow magnet, which has
been fitted to a pointer axle. The position of a second annular
follow magnet fitted on the pointer axle is transferred to the
scale by means of the pointer.
Application
The BGF meter is suitable for flow measurement of liquid or
gaseous products in pipes. The special advantage is that it
can be used for all directions of flow. It shows the current flow
rate in volume or mass per unit in time.
Applications
Flow measurement, dosing, monitoring, adjusting and control
of liquid and gaseous products. The meter’s design makes it
ideal for processes under difficult and adverse operating
conditions.
The devices are available with additional electrical equipment
for process monitoring and control.
