Sierra Instruments manufacturers high performance mass flow meters and mass flow controllers for nearly any gas, liquid, or steam application. Thermal Mass, Transit-Time Ultrasonic, Vortex Shedding and Multivariable flow meters are available in both standard and customized versions for applications in laboratory, industrial, and hazardous environments. Sierra's flow measurement technologies precisely measure or control very low flows down to less than 1 sccm full scale as well as extremely high flows of gas, liquid, and steam. |

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:
|
|
|
Compod can be utilized in many common gas process control applications. In simple systems, it replaces expensive PLCs or computers and controls the process directly. In others, it is a key link between a master computer or process controller and the gas control instruments. |
