With its advanced capabilities, the Compod™, coupled with Sierra’s Smart-Trak® 2 Model 100 mass flow meters or controllers greatly simplifies basic flow control installations and permits networking of multiple instruments using open-source MODBUS RTU protocol.

Two digital outputs and one analog input can be configured by the user for a wide variety of process controls including:

• Gas mixing and blending
• Batch control
• Leak Testing
• Process monitoring
• Pressure monitoring and control
• Gas ratio control
• Triggering alarms
• Starting or stopping gas flows automatically under user-defined conditions
• Gas flow totalization with adjustable pulse output

• RX485 MODBUS RTU, optically isolated
• 2 Analogue inputs, user configurable
• 24Vdc; Compod requires 100mA above power required by 100
