Whisper™ MCW Series Controllers
Low Pressure Drop Mass Flow Controllers with Laminar Differential Pressure Technology
Low pressure drop mass flow controllers are ideal for systems with limited source pressure. Instruments create minimal pressure drop (as low as 0.07 PSID).
- 98 pre-loaded gas calibrations — switch without losing accuracy
- Measures mass flow, volumetric flow, temperature, and pressure
- Instant warm-up
- 0.01 – 100% measurement range (10,000:1 turndown)
- Laminar differential pressure (DP) mass flow measurement technology
- Configurations available for bidirectional control of flow
- As a low pressure drop mass flow controller, you can control flow and measure invisibly. Won’t consume a low pressure differential.
- Limited Lifetime Warranty
