Abstract

A air meter calibration testing device for testing temperature compensators, comprises a vortex cooling tube, a cold air chamber, a hot air chamber, a bleed valve, a motorized drive system and a compressed air regulator. The vortex tube converts compressed air from the regulator into distinct cold and hot waste air streams. The cold stream is provided to the cold air chamber and the hot stream is provided to the hot air chamber. The regulator is used to adjust the pressure of the compressed air supplied to the vortex tube and accordingly to adjust the temperature in the cold air chamber. The bleed valve is coupled to the hot air outlet of the vortex tube and is used to adjust the air flow of the hot air stream into the hot chamber and accordingly the temperature in the hot air chamber. The motorized drive system is adapted to provide volumetric input to the temperature compensator by actuating the drive shaft of the temperature compensator to simulate connection to a air meter.
