Alicat Scientific has expanded its communications protocol offerings, adding EtherNet/IP and DeviceNet as options on its line of mass flow, pressure, and liquid instrumentation. The new industrial automation protocols enable integration of Alicat instruments with PLCs running EtherNet/IP or DeviceNet. Real time data-including mass flow, volumetric flow, pressure, temperature, selected gas calibration, setpoint, and totalised flow of gases-can be read centrally by the PLC and used to manage Alicat controllers and meters. Users may change setpoint or gas selection, and issue other commands to Alicat instruments using a DeviceNet or EtherNet/IP enabled PLC or computer. With response times as low as 100 ms, Alicat controllers rapidly and precisely monitor and control critical process parameters in chemical, medical, manufacturing and power industries.
