FIELD: systems monitoring pneumatic transport of loose materials in agriculture, in flour-grinding and mixed feed production. SUBSTANCE: L-shaped tube with holes of total and static pressures connected to recording unit is fitted with tip in the form of cone mated with hollow cylindrical part. Through holes are made in cylindrical part in point of its mating with cone. Internal space communicates with hole of total pressure of tube. Cylindrical part has holes matched with holes of static pressure of tube and in plane of through holes communicating through internal space with holes of total pressure of tube. It carries protrusion. Through holes displaced with reference to holes of total pressure of tube are made in conical part in parallel to symmetry axis of tube. EFFECT: increased measurement accuracy, reduced energy consumption for transport of impurities in air flow. 2 dwg
