Design of cryogenic venturi flow display instrument based on embedded
To meet the need for real-time flow monitoring in a cryogenic refrigeration system,a design of cryogenic venturi flow display instrument was presented based on the embedded system,targeting the cryogenic venturi flow meter.This instrument integrated functions such as pressure and differential pressure signal collection,cryogenic monitoring,and mass flow calculation,which can make it suitable for flow measurement of fluids in various states under different pressures,differential pressures,and temperature conditions.The flow display instrument has several advantages,including ease of use and high integration.The re-sults show that this cryogenic venturi flow display instrument has a maximum test error of 0.557％,which can meet the require-ments for flow monitoring in a cryogenic environment.
