Alicat Scientific MCW–Series Whisper Low Pressure Drop Gas Mass Flow Controllers

Description

Alicat Scientific MCW–Series Whisper Low Pressure Drop Gas Mass Flow Controllers. Condition is "Used".
MCW–Series (Whisper™): Low Pressure Drop Gas Mass Flow Controllers
Responsive gas flow control with minimal system impact.
Alicat Whisper™ mass flow controllers with low pressure drop
are ideal for controlling mass and volumetric flow rates when there is little available system pressure. Low pressure drop minimizes system impact, enabling flow control at near-atmospheric pressures and shortening system response times. We’ll use your application parameters to customize your valve and PID tuning to ensure that it delivers fast and stable control while maintaining low pressure drop.
Versatile.
Control pressure while monitoring flow rates, select another gas calibration on the fly or define your own gas composition with COMPOSER™.
Connected.
Easy integration into your digital industrial network with EtherNet/IP, EtherCAT, DeviceNet, Profibus, Modbus (RTU and TCP/IP) or serial communications options.
Durable.
Backed by annual recalibrations and our limited lifetime warranty, an Alicat instrument will keep your process running smoothly, even in challenging environments, for years to come.
