EP SMF®​-SonicMasterFlow®​

Calibration stand with Laval nozzles for representing the volumetric flow or mass flow

  • Calibration with air

  • Use of critical/sonic nozzles

  • Approved by the PTB as a calibration standard

  • Highest accuracy – up to 0.15% MV

  • High long-term stability – recalibration period up to 10 years for Laval nozzles

System Overview

The series of SMF® nozzle test stands is specially designed for air calibration. As measuring elements critical/sonic nozzles are used. Depending on customer requirements, up to 18 critical/sonic nozzles can be combined. For the register, EP offers different designs: Drum Design, Block Design & Register Design. Another variant is a mobile system: the EP SMF® - Mobile Flow Calibrator, a compact measuring system for flow calibration.
