FIELD: flow-measuring equipment.
SUBSTANCE: Coriolis flow-measuring apparatus has at least one flow tube molded of plastic by die casting and placed in plastic case. Plastic flanges are connected with ends of plastic beans of at least one flow tube. For different versions of flow-measuring apparatus, balancer, fitting plates, spools of detectors and drive are also made of plastic. During die casting process, rod of channel for matter's flow is formed of metal having low temperature of melting. Molded rod is inserted into envelope mold, which has cavity forming outer surface of plastic structure of Coriolis flow-measuring apparatus. Cavity is filled with plastic. Ready plastic flow tube is removed of envelope mold and then rod of channel to let flow through is also removed from tube.
EFFECT: simplified process of manufacture; reduced cost.
