FIELD: flow rate metering systems.
SUBSTANCE: Coriolis flow rate meter includes flow rate metering tube passing through hollow balancer whose ends are joined with tube by means of rings soldered by hard solder. Outer surface of rings and joined to it inner surface of end portions of balancer are conical. Coefficient of temperature expansion of balancer exceeds that of flow rate metering tube and that of connection rings. In variant of invention in order to compensate difference of temperature expansion of balancer and connection rings, additional ring is used. Additional ring has cone-narrowed outer surface soldered by hard solder to cone inner surface of each ring and it has inner surface soldered by hard solder to flow rate metering tube.
EFFECT: reliable joint of members of oscillating construction, increased useful life period of flow rate meter.
