Short-term storage
For short-term periods (less than one week), keep the sensors in the flow chamber. Make sure that
purge gas is constantly supplied to the TC sensor. Keep the indicating instrument energized or use a
purge gas backup unit.
Long-term storage
For long-term storage (more than one week), remove the sensor from the flow chamber. Refer to the
documentation supplied with the sensor for instructions on how to remove, clean and store the
sensors.
Clean the LDO sensor with water and put the protection cap on the collar to keep the membrane
away from light. Do not use chemicals to clean the LDO sensor or damage to the membrane can
occur.
Troubleshooting
Problem Possible cause Solution
There is beverage
sample suction
through the gas
supply. The gas supply is
disconnected with the
system still under pressure. Flush the gas tubing through with water. Dry the tubing with
a jet of gas.
No beverage flows
in the tubing. There are defective fittings
or tubing connections. Examine all Swagelok fittings and tubing connections for
leaks.
Use two wrenches to adjust the fittings. Examine the fitting
on the flow chamber, which can split if there is too much
pressure.
No beverage flows
in the tubing. There is a blockage in the
inlet or outlet ports of the
flow chamber. Make sure that the inlet and outlet ports of the flow chamber
are not clogged.
1. Carefully remove the nuts that attach the tubing in the
Swagelok inlet or outlet fittings of the flow chamber.
2. Clean and flush the flow chamber with hot water.
3. Let the flow chamber dry.
4. Assemble the flow chamber.
Note: Refer to the sensor documentation for additional information.
