Flow calibratormax. 150 psig

The Gas Flow Calibrator is a piston-prover-based test stand utilizing sonic nozzles to provide metrology for all gas metering technologies. This system:
calibrates flow meters at pressures ranging from atmospheric to 150 psig
tests flow meters both at atmospheric and elevated pressures
supports a wide variety of meter types (listed below)
does not require tight environmental temperature control
supports common calibration gasses

Key Features
Scaleable expansion in mass flow and accuracy
No constraints on test-section diameter or length
Scaleable range and accuracy utilizing a single system controller
No oils or hazardous materials (Mercury) required
Total automation with closed loop control
