MEASURING DEVICE FOR DETERMINING AT LEAST ONE PARAMETER OF FLUID MEDIUM FLOWING THROUGH CHANNEL Russian patent published in 2019 - IPC G01F15/14 

FIELD: measurement.

SUBSTANCE: claimed solution relates to a device for determining at least one property of fluid streams, namely, liquids and / or gases. Measuring device (10) for determining at least one parameter of a fluid flow passing through channel (30), primarily mass flow of air sucked into an internal combustion engine, having housing (12), which is in form of an inserted probe placed in a flow tube and in which said channel (30) is formed, and at least one crystal (36) located in said channel (30) with a sensor for determining the parameter of the fluid, wherein housing (12) has body (16) and cover (18), and channel (30) has inlet (20), which when the inserted probe is inserted into the flow tube, faces main flow direction (22) of the fluid flow in the flow tube, and at least one outlet (32). Channel (30) is made in cover (18), which is connected to housing body (16) with a power closure and has installation recess (60), housing body (16) has protrusion (48), which protrudes from housing body (16) in first direction (54) of length and which, to form a connection with a power closure, enters said installation recess (60), and housing (12) has a space intended for electronics (46), wherein crystal (36) with the sensor is located on holder (34), which projects into channel (30) from the space intended for electronics (46) in second direction (58) of length, and protrusion (48) is located opposite the space intended for electronics (46) with separation from it by channel (30) located therebetween in second direction (58) of length and runs perpendicular to said second direction (58) of length.

EFFECT: technical result is to provide unambiguous determination of the position of the cover and the housing relative to each other.
