Process Monitoring

Made easy with SmartTrak and Compod

With a SmartTrak mass flow controller upgraded with Compod, process monitoring is made easy.  A SmartTrak MFC controls the flow rate, while the Compod facilitates monitoring the pressure and temperature of the process. This makes the information available from one node on an RS485 network.

In this example, temperature and pressure transducers are installed near the MFC. The 4-20mA signals from both are fed to the analog inputs of the Compod. The Compod communicates via its RS485 MODBUS output to the network. When the master control system needs to know information on this process, it sends a request to the Compod, which then reports the flow, temperature and pressure.

The control system can also regulate the flow by sending setpoint commands to the MFC via the Compod.
