OMEGA®FMA-7000E Mass Flow
Controllers accurately measure gases
on the basis of mass flow. The flow
sensor produces an electrical output
signal linear with the flow rate used for
indicating, recording, and/or control
purposes. It eliminates the need for
continuous monitoring and readjustment
of gas pressures to provide a stable gas
flow. This is accomplished automatically
by an electromagnetically actuated
flow rate control valve.
OPERATING PRINCIPLE
The operating principle of the controller
is thermodynamic. A precision power
supply directs heat to the midpoint of
the sensor tube carrying the flow. On
the same tube, equidistant upstream
and downstream of the heat input, are
resistance temperature measuring
elements.
With no flow, the heat reaching each
temperature element is equal. With
increasing flow, the flow stream carries
heat away from the upstream element,
and carries it towards the downstream
element. An increasing temperature
difference develops between the two
elements and this difference is
proportional to the mass flow rate of
the gas. A bridge circuit interprets the
temperature difference and an amplifier
provides the output to the control
circuitry as well as a 0 to 5 Vdc
output signal.
Mating connector
included.
