Description
Originally built to test impulse lines on
gas cooled reactors, ILITS-3 is designed
to detect minor changes in impulse line
conductance caused by clogging or
corrosion. Safety life cycle testing is now
a requirement in many industries to
prevent plant failure and potentially
hazardous releases to atmosphere.
Testing is done by injecting a constant
known gas flow though a line and measuring
the pressure head required to
maintain this flow. The test set has an
adjustable regulator on the rear panel to
set the input pressure to the internal
mass flow controller, the flow command
to the mass flow controller is user
selectable from the front panel. Output of
the mass flow controller is injected into
the line to be tested and the output port
pressure is monitored by an internal
capacitance manometer.
Both pressure head and mass flow are
clearly displayed on the LED front panel
displays, and analogue or digital outputs are
available for data logging.
As the test set is designed for field applications,
it is housed in a portable instrument
case fitted with an adjustable carry handle /
desk stand. Use with a clean dry inert test
gas is ideal, but the unit is fitted with an inlet
filter and pressure regulator to allow it to be
used from a compressed air supply.
Test gas flow accuracy is assured by the use
of a mass flow controller, which is not affected
by line pressure or temperature
changes. Similarly a capacitance manometer
with accuracy of 0.3% of reading and resolution
of 0.01% of full scale is used to provide
the pressure measurement sensitivity required.
UKAS (ISO17025) calibration certificates
are included, and Chell Instruments are
able to perform the recommended annual
recalibration.
