FIELD: instrument making.
SUBSTANCE: primary converter of flowmeter, which includes housing (4) of magnetic induction converter, sleeve (12) with rotation chamber (5) in which ball (13), straightening vane (10) and screw (14) is located, is arranged so that supply pipeline connected to housing (11) of sensor and straightening vane (10) are located below rotation chamber (5) of ball, and outlet pipeline of measured medium and screw (14) are located above rotation chamber (5).
EFFECT: invention allows improving reliability and durability of primary converter of ball-type flowmeter owing to improving ball cooling conditions during operation of flowmeter owing to removing gas phase from rotation chamber.
