Alicat MCW Whisper Series Mass Flow Controller

  • Ultra-Low pressure drop mass flow controller
  • Flows from 0.5 SCCM up to 500 SLPM
  • 98 Preloaded Gases and Gas Mixtures
  • 50 – 100 ms control response

Alicat MCW & MCRW Whisper Series mass flow controllers allow you control your gas with minimal pressure drop in your process. Pressure drops are as low as 4 mbar at full scale flow rates, meaning they can control and near atmospheric pressures or on just a whisper!

The whisper series mass flow controller is repeatable and accurate with calibrations up to +/- 0.4% of reading accuracy and every whisper device has a 200:1 turndown ratio with flow rates starting from 2.5 microliters per minute up to 500 SLPM.

The mass flow controller can be used as a standalone controller with the use of local display and push button keypad. The local display allows the user to see all flow data visible on one screen (mass flow, volumetric flow, absolute pressure, temperature) as well as control the flow or pressure of the gas.
RS-232 communications are standard as well as an analogue output signal such as 0 – 5 VDC.

Every Alicat device is backed by the manufactures limited life time warranty and ships with a NIST traceable calibration certificate.

MCW & MCRW whisper series mass flow controllers have a maximum operating pressure of 45 PSIG. There is fully adjustable PID control valve tuning for best speed and stability whilst the MCW & MCRW can control mass flow, volumetric flow or absolute pressure with one device.
