DATA SHEET Mass Flow Controllers & Meters Models 5850EM & 5851EM Metal Sealed, Thermal Mass Flow Meters & Controllers for High-pressure Gas Flows The Brooks® Model 5850EM Metal Sealed Mass Flow Controller has all the features of the standard Model 5850E plus all metal seals for outstanding leak integrity and cleanliness. The Model 5850EM eliminates the need for continuous monitoring and readjustment of gas pressures to provide a stable mass flow. The Brooks® Model 5851EM Metal Sealed Mass Flow Controller offers state-of-the-art performance in high flow gas measurement and control. It combines the outstanding leak integrity of metal seals with a variety of options which allow maximum flexibility. The heart of the system is the highly stable sensor which produces an electrical output signal linear with flow rate. This signal is used for indicating, recording and/or control purposes without the need for an auxiliary auto-zero circuit.
