FIELD: measuring engineering.
SUBSTANCE: testing device comprises two identical reference mass flow meters that operate on the basis of the Coriolis effect and are interconnected in series, control unit, and supplying and return pipelines that are provided with valves and connect the device with pipeline for fluid that receives the flow meter to be tested. The control unit is made of a processor and simultaneously receives and process signal from tree flow meters. One of the reference flow meters can be used as a testing measuring device for the other reference flow meter.
EFFECT: reduced sizes and simplified servicing.
