Gear type flow meters VCA / VCG I Construction 1 Housing 2 Cover 3 Gear 4 Plug 5 Sensor 6 Bearing Consisting of two high-precision gears, the measuring unit is driven by the liquid flow based on the displacement principle. The gears run in an almost contactless manner in the measuring chamber. The bearing consists of ball and plain bearings. The measuring principle does not cause any pressure or volume flow pulsation. Because there is no need for settling sections on the inlet and outlet side, machines/ plants can be designed to be more compact. All moving parts are lubricated by the measuring...
