The MT3809 armored variable area (VA) flowmeter from Brooks Instrument provides unprecedented flexibility regardless of application, process configuration or flowrate. It works accurately across a vast range of operating temperatures -- from -196 C to 420 C (-320 F to 780 F) -- and at pressures to 1380 bar (20K psi). Even in demanding applications measuring gases, liquids and steam, the MT3809 delivers 2% full-scale/1.6 VDI accuracy. The explosion-proof housing meets the most stringent hazardous-area classifications worldwide, and a flameproof option is available for IIC/Class 1 Division 1 locations. Rugged stainless steel construction and weldneck flanges provide long-term durability in all configurations. No back pressure is needed for gas applications, and ASME sealing specifications are met with a standard gasket, eliminating the cost of custom gaskets.
