FIELD: measurement engineering.
SUBSTANCE: device can be used for measurement of mass discharge of air coming to internal combustion engine. Device has measurement part with case, which is inserted into mounting hole in pipeline's walls; case is made in form of removable unit. Bypass channel is made in case. Channel has at least one input hole communicating with pipeline. Channel also has at least one output hole ending in pipeline and measurement channel, where measurement member is disposed. Measurement channel changes to declining channel; both members have C-shape together. Flow divides completely to two separate flows at entrance part of bypass channel disposed behind entrance hole along flow. First flow completely flows in measurement channel and the other one moves completely through at least one separation hole.
EFFECT: optimal protection of measurement member from drops of fluid and/or solid particles.
