Brooks Instrument manufacturers solutions for flow, pressure, and level measurement solutions

Overview

Like other Brooks Instrument Coriolis devices, Quantim^® sensors and transmittors offer all the benefits of Coriolis for low flow liquid and low flow gas applications.

Quantim sensors provide superb communication flexibility. Combined with Brooks’ newest transmitter, the mass flow sensor lets you access more data in your plant’s process language (Modbus®, HART®, FOUNDATIONTM Fieldbus, PROFIBUS® PA).

In addition, multivariable output for mass flow or volumetric flow and density or temperature adds diagnostic capabilities and reduce the need for additional instrumentation.
