Wedge flow meter is a new differential pressure flow meter. It not only breakthroughs the measurement problem of the tar, bitumen, oil residues of the high viscosity of the liquid medium flow in the coking, oil refining and chemical industry enterprises, but also is widely used in a highly corrosive chemical enterprises, and with the temperature precipitation changes in the crystallization of a saturated or unsaturated acid, alkali and salt solution in the flow measurement.
