Compod Programmable Control Module

Multi-Drop RS-485/MODBUS RTU Communications

Simplify basic flow control installations with Compod!

With its advanced mass air flow sensor capabilities, the Compod™, coupled with Sierra’s Smart-Trak® 2 Model 100 mass flow meters (MFM’s) or controllers (MFC’s) greatly simplifies flow control systems and permits networking of multiple instruments using open-source MODBUS RTU protocol. Compod™ also monitors the functionality of the mass flow meter or controller and includes diagnostics, notifying users of valve faults or system upsets.  By adding the Compod™ flow control module to a new or existing Smart-Trak® MFM or MFC, end users can take complete control. Two digital outputs and one analog input can be configured by the user for a wide variety of process controls including:

Plug our innovative new Compod into the face of any Smart-Trak 2 and streamline, simplify and save.  

With a Compod, Smart-Trak 2 becomes a fully network-enabled multi-drop RS-485 / Modbus RTU device, allowing you to perform the same functions as much more complex systems at a fraction of the cost.

Daisy-chain multiple MFC’s on a single network, then send and receive data, alarms and commands  or perform remote diagnostics and data logging

More Features:

•    Controls simple processes without the need for external PLCs or computers
•    Acts as a vital link in a complex process control network
•    Monitors the operation of instruments and provides potential problem alerts
•    Is available with a local LCD Display for local monitoring
•    Can be used with new instruments or added to existing models


With all of the above features, Compod™ can perform the same functions as much more complex control systems at a fraction of the cost, so using Compod™ is smart in more ways than one.

An internal Compod can also be added inside the industrial enclosure of the Max-Trak® Model 180 to obtain most functions.

Users can utilize Sierra’s included software or write proprietary software using open-source MODBUS protocol to configure standard functions for the Smart-Trak®.  Compod’s two digital output channels and the analog input channel and a configurable pulse output channel can automate gas processes without the need for an external PLC or computer.
