The Brooks GT1600 Glass-Tube Variable Area Flow Meter are a family of meters with a rugged design for long-lasting performance with low and high-flow gas and liquid applications where viewing the process is important. These meters are for general use in applications with moderate metering accuracy requirements. Typical accuracy ranges are 1% to 10% full scale, depending on the model selected. They are ideal for purge type service, seal oil systems, bearing lubrication and cooling water indication.

The Brooks GT1600 Glass-Tube Variable Area Flow Meter are configurable to retro-fit existing Brooks Instrument GT1000, GT1300 and Full-View® 1100 Series meters (models 1110, 1114, 1140, 1144).
