Alicat Scientific MCDW | Whisper Bidirectional Low Pressure Drop Controller | 0.5 SCCM-500 SLPM, ±0.4% of span
The MCDW pairs the Whisper low pressure drop flow body with bidirectional control, covering 0.5 SCCM to 500 SLPM full scale at up to 60 PSIA. Accuracy is quoted as ±0.4% of total span from positive to negative full scale, with 100 ms control response. Alicat positions it for controlling pressure in a closed volume while reading flow, which makes it a practical leak-check tool.
