BULK Fuel Flow Meters BM

BM meters are positive displacement meters for liquids. They are designed for measuring liquids in both transfer and process control applications. Their design makes them easy to use and suitable for a wide range of applications. The meter consists of a housing in which two displacer rotors and a central single blocking rotor rotate in synchronized relationship within three cylindrical bores with no metal-to-metal contact in the chamber. Each rotor is supported on either end by a bearing plate through which the rotor shafts protrude. The displacement rotors move alternately through the two half cylinder bores of the meter element, while the single blocking rotor rotates within its bore such that a continuous capillary seal is created between the undosed, upstream product and the metered, downstream product. A distribution gear is located at one end of each rotor shaft. The blocking rotor gear, which has twice as many teeth as each of the displacing rotor gears, rotates at half the speed of the displacing rotors.
