FIELD: engines and pumps.
SUBSTANCE: proposed device is arranged inside radial-flow fan compression chamber 7 and comprises housing 11 accommodating through tube 12 arranged along lengthwise axis and exposed at both faces 12a, 12b. Said housing comprises first part 13 to rest on fan housing and second part 15 to dip in flow generated by fan compression chamber by setting tube end face inside said flow to measure pressure signal. Note here that second part 15 features cross section located across lengthwise direction and has aerodynamic profile shape with low drag.
EFFECT: higher efficiency of ventilation.
