The BM Series Flow Meter operates on the positive displacement principle, where the product enters the meter and causes the rotor to revolve through pressure on the vanes. The proximity of the rotor to the body forms an efficient seal, guiding the vanes through the measuring crescent, where the volume of the product is accurately measured. An extension shaft transmits the rotor revolutions to a pulse transmitter or a mechanical register, facilitating precise measurement and monitoring.
