Kobold BGN All Metal Flowmeter
The Kobold BGN meter is suitable for flow measurement of Liquid and Gaseous products in pipes. It shows the current flow rate in volume or mass per unit in time.
The fluid flows from bottom to top through the meter tube of the flowmeter. The float is lifted until an annular gap between the meter ring and the cone-shaped float is produced, which corresponds to the flow. The forces acting on the float are in equilibrium. The forces that are mainly acting on the float comprise buoyancy according to the principle of Archimedes, the flow force of the medium and the weight force. Each position of the float corresponds to a flow value measured during calibration, which is transferred to a scale. The BGN variable area flowmeter consists of a meter tube with connections, a meter ring, and a conical float. By means of a magnet, the position of the float is transferred by means of 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.
The materials and construction of the BGN flowmeter enable it to operate in highly demanding environments of high pressure up to 600 Bar and high temperatures up to 350°C. ATEX approved versions also allow operation in hazardous areas.
