In practice, some empirical modification is required; this helps to compen-
sate for the non-ideal performance of the meter. For example, the actual
factor for argon is 1.395, rather than the 1.401 estimated in the example.
Please consult AMETEK Process Instruments for assistance, before run-
ning gases that are not listed in the menu on the 3050-RM analyzer.
If a custom gas is entered, the conversion to units of dew point will be
based on an ideal gas model, without any enhancement factor.
Gas Saver
In the default configuration the Model 3050-RM analyzer runs with the
internal bypass valve open, so that the total flow through the analyzer
is greater than 1 SLPM. This high sample flow rate helps to improve the
response speed of the system. The gas-saver feature allows the user to
control the state of the bypass valve so that the analyzer runs on a sample
flow rate of 150 SCCM. The operation of the valve can be controlled
by checking the Gas Saver box (to close the bypass valve) or leaving it
unchecked(to leave the bypass valve open).
Sensor Saver
In the default configuration the Model 3050-RM analyzer operates with
a rapid cycle time to minimize system response time. The sensor-saver
feature allows the analyzer to operate with a slow cycle time, maximizing
the cell life but minimizing system response time. The operation of the
valve can be controlled by checking the Sensor Saver box (to operate with
a slow cycle time) or leaving it unchecked (to operate with a rapid cycle
time).
