THE BROOKS SMART MASS FLOW PRODUCTS
The Brooks Smart Mass Flow Meters, models 5860/MF60, 5861/MF61, 5863/
MF63 and 5864/MF64 measure gas flow accurately. The heart of the system, is
the thermal mass flow sensor which produces an electrical output signal as a
function of flow rate. In addition the Brooks Smart Mass Flow Controllers,
models 5850/MF50, 5851/MF51 and 5853/MF53 are equipped with an electro-
mechanical valve, allowing them to control gas flows. The flow ranges per model
are listed in Table 2-1 below.
