MassRateTM 5700
DESCRIPTION
The Brooks® MassRate 5700 is a gas flow meter specially
designed to satisfy the needs of purge gas, process
analysis and analytical flow measurement applications.
The MassRate 5700 utilizes a proven thermal mass flow
sensor which provides excellent repeatability, wide
turndown and an electrical output signal. It has a rugged
all stainless steel construction and no moving parts
providing superior corrosion resistance and long- term
reliability. The MassRate 5700 is an economical meter
with an electrical output signal making it ideal for replacing
turbine meters, variable area meters and other volumetric
devices.
