Kobold BGF Counter Variable Area Flow Meter

Kobold BGF Counter Variable Area 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.

Kobold BGF Counter Variable Area Flow Meter 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.

Measuring / switching range:

  • 10 - 100 ... 4000 - 40 000 l/h water
  • 0.3 - 3.0 ...110 -1100 Nm³/h air

Connection: flange DN15 ... DN100, ANSI ¾ ... 4"
Material: stainless steel 1.4404, option PTFE-lining
pmax: PN40 (16) bar, on request max. PN600 bar
Temperature range: -40 ... +200°C (-40 ... +350°C on request)
Accuracy: ±2 % of full scale
Options: contacts, analogue output, totalizer, Hart®, Profibus® PA, ATEX

Flow measurement, 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.
