Overview
The Burger & Brown Engineering Smartflow 0.5-2.5 GPM flow indicator is a mechanical flowmeter with integrated gauge designed for monitoring and controlling liquid flow in injection molding, cooling, hydraulic, and plumbing systems. Burger & Brown Engineering is internationally known for its SMARTFLOW® proprietary products, which comprise a line of multi-port manifolds and flowmeters for monitoring flow, temperature, and pressure. The 0.5-2.5 GPM range makes it suitable for moderate flow applications where precise visual indication is required.
