The BGF meter operates using the principle of variable area flow measurement, which is explained as follows:

• Flow Interaction: As the fluid enters the meter, it passes through a tube that contains a conical float and a compression spring. The flow rate determines the float’s movement along the tube, which can be positioned either vertically or horizontally.
• Float Movement: The float moves in response to the force exerted by the fluid. As the flow rate increases, the float shifts further along the tube. If the flow rate decreases, the float returns to its original position due to the spring mechanism. The float stabilizes at a point where its weight is balanced by the flow force.
• Flow Rate Indication: The float’s balanced position corresponds to a specific flow rate, which is transmitted via a magnetic coupling to a display. The display, with a calibrated 90° scale, provides an accurate, easy-to-read measurement.
