Testing
Refrigerator Cooling Coils
A manufacturer of refrigerator appliances was
testing the 12-foot-long refrigeration coils of
their systems using labor intensive techniques.
TME offered a customized MDT-50/100 Leak and Flow
Tester that utilized the simpler parts of the
customer procedure and provided quantified leak
and flow value that consistently identified acceptable
and unacceptable parts. Because of the size of
the test item, a test operator was stationed at
each end. The tester was connected to one end
of the test item and a flow test was performed
with the distant end open. An easily visible light
indicated the test result: if an occlusion was
present and the item failed the flow test, a "red"
light indicated the failure and the test was terminated.
A "yellow" light indicated a Flow Test
Pass, and the secondary test operator plugged
the open end to enable a Leak Test. A "red"
light again indicated a failure, and a "green"
light signified a good part. Working as a partner
to the customer in the improvement of process
efficiency, TME offered not only simple, reliable
and fast instrumentation, but customized fixture
handling, operator control and visibility interfaces.

Flow
Testing Vacuum Cleaner Accessories
 An
appliance manufacturer of vacuum cleaner products
was introducing a new accessory to its line. The
device provided a spray of liquid for cleaning
and required precise flows of the cleaning agent
for proper operation. TME designed a customized
holding fixture for the complex geometry of the
device and, using the TME Solution™ Leak
and Flow Tester, provided a dry air mass flow
test to quantify the flow rate equivalent of the
flow of cleaning agent through the device. TME
and the customer worked together to determine
the range of operation and the required repeatability
of the tested part using the quantitative results
of the mass flow tester.

Leak Testing Hydraulic Motors for
Labor Savings
A leading manufacturer of industrial hydraulic motors
was introducing new production assembly techniques
in its manufacturing plant. Previous procedures
identified leaks in completely assembled motors
using hydraulic oil. Rework of failed units was
time consuming and costly. Working with TME, the
manufacturer determined that a dry air, pressure
decay leak test with high sensitivity would find
misassembled or defective parts in the sub-assembly
process. Failed parts at the subassembly level could
be more easily repaired at much lower labor cost.
The TME Solution™ Leak Tester was programmed
to quantitatively identify and test leak rates for
these subassemblies with a known standard reference.
