SmartTrak 140 low pressure drop flow meters offers precision gas mass flow control of expensive process gases, where minimal pressure drop is a key consideration for cost savings and efficiency, the SmartTrak® 140 low pressure drop flow meter controls up to 500 slpm with an ultra-low ΔP of 4.5 psid (310 mBard) much better than typical ΔP values of 25 psid (1700 mBard) for equivalent mass flow controllers on the market.","Our digital communications solutions offer engineers and systems integrators, full system integration and networking capability with Sierra's mass flow control systems. Digital communications solutions include: Foundation Fieldbus, Modbus RTU, and Profibus DP. For enhanced networking capability, including two digital relays, totalization, inputs, and display, add the Compod Control Module™ to easily program a wide variety of common flow systems and process controls ranging from gas mixing and dilution to leak testing.
