PARTIAL FLOWMETER Russian patent published in 2018 - IPC G01F1/10 

FIELD: machine building.

SUBSTANCE: invention relates to the field of engineering, in particular to the field of measurement of viscous liquids and gases, and can be used to produce articles such as flowmeters. Partial flowmeter includes a housing with an internal flow channel where a flow distributor arranged in the form of a shell is installed in a coaxial manner with a flow converter and a signal pickup unit inside it, at that at least one outer edge of the shell is chamfered, longitudinal ribs are radially fixed on the outer side of the shell. At that at least one distribution ring is fixed to at least one end surface of the longitudinal ribs with an axially flow channel. Claimed technical solution allows to obtain a technological and economical partial flow meter with high metrological characteristics and low head losses.

EFFECT: expansion of the measurement range by increasing the sensitivity of the claimed device at low flow rates, as well as reducing head losses due to small shell diameters; increase of manufacturability and economy of manufacture of a partial flowmeter at the expense of use of the same unified flow converter in a wide range of flowmeters dimension-types.
