C. Additional Notes for Liquid Applications
In addition to the topics already discussed, the following general
application notes pertain to the use of GE Panametrics moisture
probes in liquid applications:
1. All M Series Aluminum Oxide Moisture Sensors can be used
in either the gas phase or the liquid phase. However, for the
detection of trace amounts of water in conductive liquids (for
which an empirical calibration is required), the M2 Sensor is
recommended. Since a background signal is caused by the
conductivity of the liquid between the sensor lead wires, use
of the M2 Sensor (which has the shortest lead wires) will
result in the best sensitivity.
2. The calibration data supplied with GE Panametrics Moisture
Probes is applicable to both liquid phase (for those liquids in
which a Henry's Law analysis is applicable) and gas phase
applications.
3. As indicated in Table A-3, the flow rate of the liquid is limited
to a maximum of 10 cm/sec.
4. Possible probe malfunctions and their remedies are discussed
in the Troubleshooting chapter of this manual.
