The Brooks Instrument 5851i Analog Thermal Mass Flow Controller accurately measures and controls gas flows of 10 - 100 slpm (Nitrogen). Brooks’ extremely stable flow sensor provides reliable, repeatable and accurate flow measurement even under varying process conditions. It eliminates the need for continuous monitoring and readjustment of gas pressures to provide a stable gas flow.

The operating principle of the Brooks Mass Flow Controller is thermodynamic. A precision power supply directs heat to the midpoint of the sensor tube carrying a constant percentage of flow. On the same tube equidistant upstream and downstream of the heat input are resistance temperature measuring elements.

With no flow, the heat reaching each temperature element is equal. With increasing flow, the flow stream carries heat away from the upstream element, T1, and an increasing amount towards the downstream element, T2. An increasing temperature difference develops between the two elements, and this difference is proportional to the mass flow rate. A bridge circuit interprets the temperature differential and an amplifier provides the output to the control circuitry as well as 0-5 Vdc output signal.

The Brooks Instrument 5851i Oxygen Analog Thermal Mass Flow Controller may still be available for purchase and support from Artisan Technology Group beyond End-Of-Life (EOL) by the manufacturer (OEM).
